Soups On Weight Loss

FitSugar — Thu, 03 May 2007 14:30:00 -0700

Good news for soup lovers...

A new study out of Penn State has found that when served a low calorie soup (made of chicken broth, broccoli, potato, cauliflower, carrots and butter) and entree, diners consumed 20 percent fewer calories compared to when they did not have soup.

If you're thinking, "I've got to get my hands on that soup recipe." Don't worry because the researchers say that you just need to stick to broth-based soups that are about 100 to 150 calories per serving. This way you get an extra course at your meal, while eating fewer total calories. Good news too, because my favorite lentil tomato soup is broth based.

Rubella

FitSugar — Wed, 08 Oct 2008 17:35:25 -0700

HEALTH GUIDE REFERENCE FROM A.D.A.M

Rubella, also known as German measles or three-day measles, is a contagious viral infection. Before a rubella vaccine became available in 1969, outbreaks of the disease occured every 6 - 9 years. Now rubella is rare in locations where vaccination is standard practice. In the United States, the measles-mumps-rubella vaccine, given to children twice before they reach school age, has led to the eradication of the disease. However, it is important for parents to make sure their children are vaccinated. If a pregnant woman contracts rubella, the virus can cause serious birth defects or even be fatal to the fetus.

What Causes It?

Rubella is caused by a virus. It can be spread in airborne droplets, such as from a cough or sneeze, from an infected person. Individuals can be contagious for as long as 1 week before a rash appears and up to 1 week after it disappears. Infants with congenital rubella syndrome (see section entitled Special Considerations for explanation) may spread rubella virus in respiratory secretions and urine for up to 2 years.

Who's Most At Risk?

These factors increase the risk for rubella:

Not being vaccinated
A person who has not been vaccinated coming in close contact with infants who have congenital rubella syndrome (such as in a hospital or day-care setting)
A person who has not been vaccinated coming in close contact with large numbers of people from countries that don't routinely vaccinate against rubella

Signs and Symptoms

Symptoms are usually mild. In up to half of all cases, the disease is so mild that symptoms are hard to identify. The most distinctive sign of rubella is swollen lymph nodes behind the ear, in the neck, and at the back of the head. A pink rash is usually the first sign in younger children. In older children and adults, it is more common to have a low-grade fever, malaise (feeling unwell), loss of appetite, swollen glands, and upper respiratory infection for 1 - 5 days before the onset of full-blown disease.

Other signs and symptoms include:

Joint pain. This is more common in older girls and women and may persist up to weeks or, rarely, months.
Conjunctivitis (inflammation of the membrane around the eye)
Pain and inflammation of the testes
Mild itching

What to Expect at Your Provider's Office

Your health care provider will perform an exam to look for common signs and symptoms, and may perform blood tests or culture a sample of fluid from the nose or throat to check for the rubella virus.

Treatment Options

Prevention

The rubella vaccine causes immunity in 90 - 95% of those who receive it. Children should receive two doses [usually as part of the combination measles-mumps-rubella (MMR) vaccine] at least 4 weeks apart. Anyone born in or after 1957 should have at least one dose of MMR. Persons born before 1957 are considered immune. Women of childbearing age should still be vaccinated prior to becoming pregnant, or take a lab test to see if they are immune to the virus, even if they were born before 1957. (Having had rubella makes a person immune for life.)

In the past, some news reports have raised concerns about whether the MMR vaccine was linked to autism. However, a population-based study investigating a potential association between the incidence of autism and the introduction of the MMR vaccine in the United States and Britain found no link between the two, and reports from the Centers for Disease Control and Prevention and the American Academy of Pediatrics have found the vaccine to be safe. It is more likely that, since autism is usually diagnosed between the ages of 18 months and 3 years -- the same time children receive the MMR vaccine -- timing caused questions about whether the events were related.

Rubella vaccine should not be given to anyone who:

Has a history of severe allergic reaction to a previous rubella or other vaccine
Is pregnant or planning to become pregnant
Has a deficient or suppressed immune system
Has a moderate to severe illness
Has received antibody-containing blood products within the previous 3 months

Treatment Plan

There is no specific therapy to fight the rubella virus. Treatment is supportive, and the infection generally resolves on its own. Complications are rare. Individual symptoms, such as fever, arthritis, and joint pain, may be treated.

Drug Therapies

Acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) can be taken to reduce fever.
A nonsteroidal anti-inflammatory drug, such as ibuprofen, can be used for arthritis or joint pain.
Aspirin or other medicines that contain salicylates should never be given to children because they increases the risk for developing Reye's syndrome -- a serious illness characterized by changes in the liver, vomiting, and seizures.

Complementary and Alternative Therapies

The MMR vaccine is the only effective prevention against rubella. No CAM method offers any immunity, but some alternative therapies may help alleviate symptoms of rubella.

Nutrition

No clinical trials have investigated the use of specific foods or nutrients to treat rubella. However, the following nutrients may be used to support the immune system in general. Check with your doctor to determine the proper dose for a child, and do not treat your child without medical supervision.

Vitamin A
Vitamin C
Vitamin E
Selenium
Zinc
Quercetin, a bioflavonoid that has antiviral effects

Herbs

No scientific studies have examined the use of herbal therapies to treat rubella. However, to treat viruses in general, remedies that stimulate the immune system and that have fever-reducing and anti-infectious properties may be used, along with herbs that reduce symptoms of rubella. These may include:

Willow bark (Salix alba, S. purpurea, S. fragilis) to reduce fever. Make a tea by boiling 1 - 2 g of bark in a cup of water, strain, and cool; or use 2 - 3 tsps. powder in 1 cup of hot water. Drink three times a day. Do not use if you are allergic to aspirin or take blood-thinning medication. Although white willow bark has not been linked to Reye's syndrome, it is similar enough to aspirin to cause concern in children under 16. Consult your doctor before giving white willow bark to a child.
Elderberry (Sambucus nigra) has shown antiviral properties in several scientific studies. Doses vary depending on the formulation, so consult a qualified herbal prescriber to determine the right dose.
Calendula flower (Calendula officinalis) for rash. Make a tea by steeping 1 - 2 g dried flowers in one cup boiling water, strain, and cool. Drink three cups per day.
Hay flower (Poa spp.) used externally for joint pain, in a preparation standardized to contain 3 - 5 mg per g coumarin
Witch hazel (Hamamelis virginiana) used externally to reduce itching
For inflammation of the eyes: eyebright (Euphrasia officinalis) and bilberry (Vaccinium myrtillus) used as a compress. Use five drops of tincture in ¼ cup boiling water, or steep 1 tsp. herb in 1 cup boiling water for 5 - 10 minutes, strain, and cool. Soak cloth or gauze in solution and apply over the closed eyes for 10 minutes, three to four times a day.

Homeopathy

Few studies have examined the effectiveness of specific homeopathic remedies. Professional homeopaths, however, may recommend one or more of the following treatments for rubella based on their knowledge and clinical experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type -- your physical, emotional, and intellectual makeup. An experienced homeopath assesses all of these factors when determining the most appropriate remedy for a particular individual.

Aconitum -- for individuals who experience a sudden fever, rash, and thirst
Belladonna -- for rubella that appears suddenly, is associated with high fever, flushed face and red lips, and heat that radiates from the skin. This remedy is most appropriate for individuals who perspire minimally and may experience strange dreams.
Ferrum phosphoricum -- this remedy is used early in the illness when symptoms are not specific and mild-to-moderate fever is present. Children for whom this remedy is appropriate tend to be tired with a mildly flushed face.
Pulsatilla -- for individuals with fever and chills that are worse in warm rooms and better in fresh air. Symptoms tend to be less intense than for the other remedies listed.

Acupuncture

Electroacupuncture (in which acupuncture points are stimulated with electrodes) successfully treated two cases of visual and hearing impairments linked to congenital rubella syndrome (see section titled Special Considerations for explanation about this condition). Acupuncture may also help relieve joint pain.

Massage

Therapeutic massage may help relieve joint pain.

Prognosis/Possible Complications

Most people who have rubella recover completely without permanent side effects and are immune to rubella afterward. This is not the case for a fetus infected in the womb. Fetal infection can cause serious long-term effects (see section titled Special Considerations).

Complications are more common in adults than children and may include:

Arthritis or joint pain -- Occurs almost exclusively in women. Fingers, wrists, and knees tend to be affected. This develops along with rash and may take several weeks to resolve.
Encephalitis (inflammation of the brain) -- More common in adults (especially in women) than in children. The severity can vary greatly. Up to 50% of people affected by this complication may die from it.
Internal bleeding, including in the skin, gastrointestinal tract, brain, or kidneys -- More common in children than in adults. This may last for days or, rarely, months.
Inflammation of the testicles, nerves, and brain
Pregnancy complications -- Rubella infection during pregnancy can lead to miscarriage or stillbirth, as well as to congenital rubella syndrome in the child (see section titled Special Considerations).

Special Considerations

If a fetus is infected with rubella in the womb, this can cause severe defects known as congenital rubella syndrome. The younger the fetus is at the time of infection, the more likely the syndrome is to occur and the more severe the effects are likely to be. Temporary effects of congenital rubella syndrome may include:

Slow growth in the womb
Low birth weight
Bleeding disorder
Overgrowth of the liver and spleen
Anemia
Jaundice (yellowish coloration of the skin, tissues, and body fluids)
Pneumonia

Permanent effects of congenital rubella syndrome may include:

Deafness
Heart defects
Glaucoma and other vision problems
Mental retardation
Behavior disorder
Diabetes mellitus
Thyroid disease
Growth hormone deficiency

Drug Approval

In 2007, duloxetine (Cymbalta) was approved for treatment of generalized anxiety disorder. Duloxetine is a dual inhibitor antidepressant.

Anxiety Disorders Under-Recognized and Under-Treated

About 41% of patients with an anxiety disorder do not receive any treatment, indicates a 2007 study in the Annals of Internal Medicine. Anxiety disorders can interfere with daily functioning, and problems worsen when people have more than one type of anxiety disorder. The study’s researchers recommend that screening for anxiety become a regular part of office visits in the same way that primary care doctors screen patients for depression.

Antidepressants and Children

The benefits of antidepressants for treating pediatric anxiety disorders appear to outweigh the risks for suicide, according to a 2007 review in the Journal of the American Medical Association. Researchers also found that antidepressants did not work as well for treating obsessive compulsive disorder compared to other types of anxiety disorders. This review was the largest to date of antidepressant use in children and adolescents. Most doctors recommend cognitive behavioral therapy as the first treatment approach for childhood anxiety disorders.

Psychological Therapies for Post-Traumatic Stress Disorder

Specially designed psychotherapies -- such as trauma-focused cognitive behavioral therapy, eye movement desensitization and reprocessing, and stress management -- are the most effective therapies for patients with post-traumatic stress disorder, according to a 2007 review in the Cochrane Database.

Introduction

Fear and stress reactions are essential for human survival. They enable people to pursue important goals and to respond appropriately to danger. In a healthy individual, the stress response (fight, fright, or flight) is provoked by a genuine threat or challenge and is used as a spur for appropriate action.

An anxiety disorder, however, involves an excessive or inappropriate state of arousal characterized by feelings of apprehension, uncertainty, or fear. The word is derived from the Latin, angere, which means to choke or strangle. The anxiety response is often not attributable to a real threat. Nevertheless it can still paralyze the individual into inaction or withdrawal. An anxiety disorder persists, while a healthy response to a threat resolves, once the threat is removed.

Anxiety disorders have been classified according to the severity and duration of their symptoms and specific behavioral characteristics. Categories include:

Generalized anxiety disorder (GAD), which is long lasting and low-grade
Panic disorder, which has more dramatic symptoms
Phobias
Obsessive-compulsive disorder (OCD)
Post-traumatic stress disorder (PTSD)
Separation anxiety disorder (which is almost always seen in children)

GAD and panic disorder are the most common. Anxiety disorders are usually caused by a combination of psychological, physical, and genetic factors, and treatment is, in general, very effective.

Generalized anxiety disorder (GAD) is the most common anxiety disorder. It affects about 5% of Americans over the course of their lifetimes. It is characterized by the following:

A more-or-less constant state of worry and anxiety, which is out of proportion to the level of actual stress or threat in their lives.
This state occurs on most days for more than 6 months despite the lack of an obvious or specific stressor. (It worsens with stress, however.)
It is very difficult to control worry. For a clear diagnosis of GAD, the specific worries should be differentiated from those that would define other anxiety disorders, such as fear of panic attacks or appearing in public. Moreover, they are not obsessive like people with obsessive-compulsive disorder. (It should be noted, however, that over half of those with GAD also have another anxiety disorder or depression.)
Patients with anxiety may experience physical symptoms (such as gastrointestinal complaints) in addition to, or even in place of, mental worries. (This latter case may be more common in people from non-Western cultures such as those with Asian backgrounds.)
People with GAD tend to be unsure of themselves, overly perfectionist, and conforming.

Given these conditions, a diagnosis of GAD is confirmed if three or more of the following symptoms are present (only one for children) on most days for 6 months:

Being on edge or very restless
Feeling tired
Having difficulty with concentration
Being irritable
Having muscle tension
Experiencing disturbed sleep

Symptoms should cause significant distress and impair normal functioning and not be due to a medical condition, another mood disorder, or psychosis. It should be noted that pure GAD is uncommon. It typically occurs with other mood disorders (anxiety or depression) or substance use.

Panic disorder is characterized by periodic attacks of anxiety or terror (panic attacks). They usually last 15 - 30 minutes, although residual effects can persist much longer. The frequency and severity of acute states of anxiety determine the diagnosis. (It should be noted that panic attacks can occur in nearly every anxiety disorder, not just panic disorder. In other anxiety disorders, however, there is always a cue or specific trigger for the attack.) A diagnosis of panic disorder is made under the following conditions:

A person experiences at least two recurrent, unexpected panic attacks.
For at least a month following the attacks, the person fears that another will occur.

Symptoms of a Panic Attack. During a panic attack a person feels intense fear or discomfort with at least four or more of the following symptoms:

Rapid heart beat
Sweating
Shakiness
Shortness of breath
A choking feeling or a feeling of being smothered
Dizziness
Nausea
Feelings of unreality
Numbness
Either hot flashes or chills
Chest pain
A fear of dying
A fear of going insane

Women may be more likely than men to experience shortness of breath, nausea, and feelings of being smothered. More men than women have sweating and abdominal pain. Panic attacks that include only one or two symptoms, such as dizziness and heart pounding, are known as limited-symptom attacks. These may be either residual symptoms after a major panic attack or precursors to full-blown attacks. (It should be noted that panic attacks can also accompany other anxiety disorders, such as phobias and post-traumatic stress disorder. In such cases, however, additional characteristics differentiate these disorders from panic disorder.)

Frequency of Panic Attacks. Frequency of attacks can vary widely. Some people have frequent attacks (for example, every week) that occur for months; others may have clusters of daily attacks followed by weeks or months of remission.

Triggers of Panic Attacks. Panic attacks may occur spontaneously or in response to a particular situation. Recalling or re-experiencing even harmless circumstances surrounding an original attack may trigger subsequent panic attacks.

Phobias, manifested by overwhelming and irrational fears, are common. In most cases, people can avoid or at least endure phobic situations, but in some cases, as with agoraphobia, the anxiety associated with the feared object or situation can be incapacitating.

Agoraphobia. Agoraphobia has been somewhat misleadingly described as fear of open spaces, the term having been derived from the Greek word agora, meaning outdoor marketplace. In its severest form, agoraphobia is characterized by a paralyzing terror of being in places or situations from which the patient feels there is neither escape nor accessible help in case of an attack. (One patient described the terror of going outside as opening a door onto a landscape filled with snakes.) Consequently, people with agoraphobia confine themselves to places in which they feel safe, usually at home. The patient with agoraphobia often makes complicated plans in order to avoid confronting feared situations and places.

Social Phobia. Social phobia, also known as social anxiety disorder, is the fear of being publicly scrutinized and humiliated and is manifested by extreme shyness and discomfort in social settings. This phobia often leads people to avoid social situations and is not due to a physical or mental problem (such as stuttering, acne, or personality disorders). The incidence of social phobia is about 13% and has been termed "the neglected anxiety disorder" because it is often not properly diagnosed.

The associated symptoms vary in intensity, ranging from mild and tolerable anxiety to a full-blown panic attack. (Unlike a panic attack, however, social phobia is always directly related to a social situation.) Symptoms include sweating, shortness of breath, pounding heart, dry mouth, and tremor.

The disorder may be further categorized as generalized or specific social phobia:

Generalized social phobia is the fear of being humiliated in front of other people during nearly all social situations. People with this subtype are the most socially impaired and also the most likely to seek treatment.
Specific social phobia usually involves a phobic response to a specific event. Performance anxiety ("stage fright") is the most common specific social phobia and occurs when a person must perform in public. These patients usually feel comfortable in informal social situations.

Children with social anxiety develop symptoms in settings that include their peers, not just adults, and they may include tantrums, blushing, or not being able to speak to unfamiliar people. These children should be able to have normal social relationships with familiar people, however.

Specific Phobias. Specific phobias (formerly simple phobias) are an irrational fear of specific objects or situations. Specific phobias are among the most common medical disorders. Most cases are mild and not significant enough to require treatment.

The most common phobias are fear of animals (usually spiders, snakes, or mice), flying (pterygophobia), heights (acrophobia), water, injections, public transportation, confined spaces (claustrophobia), dentists (odontiatophobia), storms, tunnels, and bridges.

When confronting the object or situation, the phobic person experiences panicky feelings, sweating, avoidance behavior, difficulty breathing, and a rapid heartbeat. Most phobic adults are aware of the irrationality of their fear, and many endure intense anxiety rather than disclose their disorder.

Obsessive-compulsive disorder (OCD) has been described as hiccups of the mind. OCD is time-consuming, distressing, and can disrupt normal functioning. Much research suggests that a critical feature in this disorder is an overinflated sense of responsibility, in which the patient's thoughts center around possible dangers and an urgent need to do something about it.

Obsessions are recurrent or persistent mental images, thoughts, or ideas. The obsessive thoughts or images can range from mundane worries about whether one has locked a door to bizarre and frightening fantasies of behaving violently toward a loved one.
Compulsive behaviors are repetitive, rigid, and self-directed routines that are intended to prevent the manifestation of an associated obsession. Such compulsive acts might include repetitive checking for locked doors or unlit stove burners or calls to loved ones at frequent intervals to be sure they are safe. Some people are compelled to wash their hands every few minutes or to spend inordinate amounts of time cleaning their surroundings in order to subdue the fear of contagion.

Over half of OCD-sufferers have obsessive thoughts without the ritualistic compulsive behavior. Although individuals recognize that the obsessive thoughts and ritualized behavior patterns are senseless and excessive, they cannot stop them in spite of strenuous efforts to ignore or suppress the thoughts or actions. OCD often accompanies depression or other anxiety disorders. There is some evidence that the symptoms improve over time and that nearly half will eventually recover completely or have only minor symptoms.

Symptoms in children may be mistaken for behavioral problems (taking too long to do homework because of perfectionism, refusing to perform a chore because of fear of germs). Children do not usually recognize that their obsessions or compulsions are excessive.

Associated Obsessive Disorders. Certain other disorders that may be part of, or strongly associated with, the OCD spectrum include the following:

Body dysmorphic disorder (BDD). In BDD, people are obsessed with the belief that they are ugly, or part of their body is abnormally shaped.
Hypochondriasis. People who have hypochondiasis have an excessive fear of having a serious disease.
Anorexia nervosa. OCD frequently accompanies this eating disorder, where the compulsive behavior focuses on food restriction and thinness.
Trichotillomania. People with trichotillomania continually pull their hair, leaving bald patches.
Tourette syndrome. Symptoms of Tourette syndrome include jerky movements, tics, and uncontrollably uttering obscene words.

Obsessive-Compulsive Personality. OCD should not be confused with obsessive-compulsive personality, which defines certain character traits (being a perfectionist, excessively conscientious, morally rigid, or preoccupied with rules and order). These traits do not necessarily occur in people with obsessive-compulsive disorder.

Post-traumatic stress disorder (PTSD) is a severe, persistent emotional reaction to a traumatic event that severely impairs one’s life. It is classified as an anxiety disorder because of its symptoms. Not every traumatic event leads to PTSD, however. There are two criteria that must be present to qualify for a diagnosis of PTSD:

The patient must have directly experienced, witnessed, or learned of a life-threatening or seriously injurious event.
The patients' response is intense fear, helplessness, or horror. Children may behave with agitation or with disorganized behavior.

Triggering Events. PTSD is triggered by violent or traumatic events that are usually outside the normal range of human experience. There is some evidence that events most likely to trigger PTSD are those that involve deliberate and destructive behavior (murder, rape) and those that are prolonged or physically challenging. Such events include, but are not limited to, experiencing or witnessing sexual assaults, accidents, military combat, natural disasters (such as earthquakes), or unexpected deaths of loved ones. PTSD may also occur in people who have serious illness and receive aggressive treatments or who have close family members or friends with such conditions.

Symptoms of PTSD. There are three basic sets of symptoms associated with PTSD. They may begin immediately after the event or can develop up to a year afterward:

Re-experiencing. In such cases, patients persistently re-experience the trauma in at least one of the following ways: in recurrent images, thoughts, flashbacks, dreams, or feelings of distress at situations that remind them of the traumatic event. Children may engage in play, in which traumatic events are enacted repeatedly.
Avoidance. Patients may avoid reminders of the event, such as thoughts, people, or any other factors that trigger recollection. They tend to have an emotional numbness, a sense of being in a daze or of losing contact with their own identity or even external reality. They may be unable to remember important aspects of the event.
Increased Arousal. This includes symptoms of anxiety or heightened awareness of danger (sleeplessness, irritability, being easily startled, or becoming overly vigilant to unknown dangers).

To further qualify for a diagnosis of PTSD, patients must have at least one symptom in the re-experiencing category, three avoidance symptoms, and two arousal symptoms. Symptoms are chronic (3 months or more). Symptoms should also not be associated with alcohol, medications, or drugs and should not be intensifications of a pre-existing psychological disorder.

Acute Stress Disorder. Experts have identified a syndrome called acute stress disorder, in which symptoms of PTSD occur within 2 days to 4 weeks after the traumatic event. Acute stress disorder can accurately identify up to 94% of victims at risk for PTSD. Between 50 - 80% of these patients actually develop the more chronic and serious disorder. In other words, it is very sensitive for identification of those at highest danger for PTSD but less successful in determining specifically who will or will not recover emotionally.

Long-Term Outlook. The long-term impact of a traumatic event is uncertain. In one study of people who survived a mass killing spree in Texas, less than half of those who suffered PTSD (28% of all survivors) had recovered after a year. In another study, PTSD became chronic in 46% of the subjects. In fact, PTSD may cause physical changes in the brain, and in some cases the disorder can last a lifetime.

Separation anxiety disorder almost always occurs in children. It is suspected in children who are excessively anxious about separation from important family members or from home. For a diagnosis of separation anxiety disorder, the child should also exhibit at least three of the following symptoms for at least 4 weeks:

Extreme distress from either anticipating or actually being away from home or being separated from a parent or other loved one
Extreme worry about losing or about possible harm befalling a loved one
Intense worry about getting lost, being kidnapped, or otherwise separated from loved ones
Frequent refusal to go to school or to sleep away from home
Physical symptoms such as headache, stomach ache, or even vomiting, when faced with separation from loved ones

Separation anxiety often disappears as the child grows older, but if not addressed, it may lead to panic disorder, agoraphobia, or combinations of anxiety disorders.

Studies suggest that an imbalance of certain substances called neurotransmitters (chemical messengers in the brain) may contribute to anxiety disorders. The neurotransmitters targeted in anxiety disorders are gamma-aminobutyric acid (GABA), serotonin, dopamine, and epinephrine. Serotonin appears to be specifically important in feelings of well-being, and deficiencies are highly related to anxiety and depression.

Examples of study findings on some neurotransmitters are:

Abnormalities in the neurotransmitters gamma-aminobutyric acid (GABA) and serotonin may have a particular role in susceptibility to generalized anxiety disorder. GABA helps prevent nerve cells from over-firing and serotonin is a brain chemical important in feelings of well-being.
Serotonin is a major player in OCD.
Changes in serotonin and dopamine have been observed in social phobia.
People with post-traumatic stress disorder have abnormalities in stress hormones (cortisol) and neurotransmitters associated with stress (epinephrine and norepinephrine). Such imbalances could account for the higher anxiety levels and a tendency to startle easily after a threat in people with PTSD.
Corticotropin-releasing factor (CRF), which is believed to be a stress hormone and a neurotransmitter, is thought to be involved in depression and anxiety by causing changes in serotonin levels.

The best way to envision the brain's response to a threat is to imagine a primal situation, such as being chased by a bear.

The Brain's Response to Acute Stress. In response to seeing the bear, a part of the brain called the hypothalamic-pituitary-adrenal (HPA) system is activated.

Release of Steroid Hormones and the Stress Hormone Cortisol. The HPA systems trigger the production and release of steroid hormones (glucocorticoids), including the primary stress hormone cortisol. Cortisol is very important in marshaling systems throughout the body (including the heart, lungs, circulation, metabolism, immune systems, and skin) to deal quickly with the bear.

Release of Catecholamines and Activation of the Amygdala. The HPA system also releases certain neurotransmitters (chemical messengers) called catecholamines, particularly those known as dopamine, norepinephrine, and epinephrine (also called adrenaline).

Catecholamines activate the amygdala, a small structure deep in the brain, which regulates control of major emotional activities, including anxiety, depression, aggression, and affection. In fact, the amygdala is sometimes known as the "fear" center.

Effects on Long- and Short-Term Memory. During the stressful event, catecholamines also suppress activity in areas at the front of the brain concerned with short-term memory, concentration, inhibition, and rational thought. This sequence of mental events allows a person to react quickly to the bear, either to fight or to flee from it. (It also hinders the ability to handle complex social or intellectual tasks and behaviors during that time.)

On the other hand, neurotransmitters at the same time signal the hippocampus (a nearby area in the brain) to store the emotionally loaded experience in long-term memory. In primitive times, this brain action would have been essential for survival, since long-lasting memories of dangerous stimuli (the large bear) would be critical for avoiding such threats in the future.

Response by the Heart, Lungs, and Circulation to Acute Stress. The stress response also affects the heart, lungs, and circulation:

As the bear comes closer, the heart rate and blood pressure increase instantaneously.
Breathing becomes rapid and the lungs take in more oxygen.
The spleen discharges red and white blood cells, allowing the blood to transport more oxygen throughout the body. Blood flow may actually increase 300 - 400%, priming the muscles, lungs, and brain for added demands.

The Immune System's Response to Acute Stress. The effect on the immune system from confrontation with the bear is similar to marshaling a defensive line of soldiers to potentially critical areas. The steroid hormones dampen parts of the immune system, so that specific infection fighters (including important white blood cells) or other immune molecules can be redistributed. These immune-boosting troops are sent to the body’s front lines where injury or infection is most likely, such as the skin, the bone marrow, and the lymph nodes.

The Acute Response in the Mouth and Throat. As the bear gets closer, fluids are diverted from nonessential locations, including the mouth. This causes dryness and difficulty in talking. In addition, stress can cause spasms of the throat muscles, making it difficult to swallow.

The Skin's Response to Acute Stress. The stress effect diverts blood flow away from the skin to support the heart and muscle tissues. (This also reduces blood loss in the event that the bear catches up.) The physical effect is a cool, clammy, sweaty skin. The scalp also tightens so that the hair seems to stand up.

Metabolic Response to Acute Stress. Stress shuts down digestive activity, a nonessential body function during short-term periods of physical exertion or crisis.

The Relaxation Response: the Resolution of Acute Stress. Once the threat has passed and the effect has not been harmful (the bear has not eaten or seriously wounded the human), the stress hormones return to normal. This is known as the relaxation response. In turn, the body's systems also normalize.

Causes

A person's genetics, biochemistry, environment, history, and psychological profile all seem to contribute to the development of anxiety disorders. Most people with these disorders seem to have a biological vulnerability to stress, making them more susceptible to environmental stimuli than the rest of the population.

Abnormalities in the Brain. Scientists are using imaging techniques, particularly magnetic resonance imaging (MRI), to identify different areas of the brain associated with anxiety responses.

An MRI (magnetic resonance imaging) of the brain creates a detailed image of the complex structures in the brain. An MRI can give a three-dimensional depiction of the brain, making location of problems such as tumors or aneurysms more precise.

Important research in anxiety disorders is focusing on changes in the amygdala, which is sometimes referred to as the "fear center." This part of the brain regulates fear, memory, and emotion and coordinates these resources with heart rate, blood pressure, and other physical responses to stressful events. Some evidence suggests that the amygdala in people with anxiety disorders is highly sensitive to novel or unfamiliar situations and reacts with a high stress response.

Obsessive-compulsive disorder (OCD) is the anxiety disorder most strongly associated with specific brain dysfunction. For example, abnormalities in a specific pathway of nerves have been linked to OCD, attention deficit disorder, and Tourette syndrome. The symptoms of the three disorders are similar and they often coexist.

A number of imaging studies have reported less volume in the hippocampus in people with post-traumatic stress disorder. This important region is related to emotion and memory storage.

The influence of the family on anxiety is complicated by both genetic and psychological factors.

Panic Disorder and Family Influence. Certain psychodynamic theories suggest, and a few studies support the idea, that some people may develop panic disorder if they cannot resolve the early childhood conflict of dependence vs. independence. In one study, for example, young adults who had experienced childhood anxiety were more likely to live with their parents until their early to mid-twenties. Many people with panic disorder perceive their parents as being extremely controlling and overly protective while showing little actual affection.

Phobias and Family Influence. Several studies show a strong correlation between a parent's fears and those of the offspring. Although an inherited trait may be present, some researchers believe that many children can "learn" fears and phobias, just by observing a parent or loved one's phobic or fearful reaction to an event. People who have social phobias and severe agoraphobia generally report less parental affection and more strictness, overprotection, and encouragement of dependence than those without these disorders.

Obsessive-Compulsive Disorder and Family Influence. One study found that parental influence played no part in obsessive-compulsive disorder if the OCD patient was also not suffering from depression. However, depression coexists in two-thirds of OCD patients, and in the study patients who had both OCD and depression reported lower levels of parental care and overprotectiveness.

Traumatic events generally trigger anxiety disorders in individuals who are susceptible to them because of psychological, genetic, or biochemical factors. The clearest example is post-traumatic stress disorder. Specific traumatic events in childhood, particularly those that threaten family integrity, such as spousal or child abuse, can also lead to other anxiety and emotional disorders. Some individuals may even have a biological propensity for specific phobias, for instance of spiders or snakes, that have been triggered and perpetuated after a single exposure.

The acronym PANDAS (Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus) is a term for an autoimmune condition associated with group A streptococcal infection in children (the cause of "strep throat" and rheumatic fever). Children with PANDAS develop tic-related disorders, including OCD and Tourette syndrome. In such cases, the OCD symptoms develop abruptly soon after the infection. It is unlikely to be an important cause of OCD.

Risk Factors

As many as 25% of all American adults experience intense anxiety sometime in their lives. The prevalence of true anxiety disorders is much lower, although they are still the most common psychiatric conditions in the United States and affect more than 20 million Americans.

Gender. With the exception of obsessive-compulsive disorder (OCD), women have twice the risk for most anxiety disorders as men. A number of factors may increase the reported risk in women, including cultural pressures to meet everyone else's needs except their own, and fewer self-restrictions on reporting anxiety to doctors.

Age. In general, phobias, OCD and separation anxiety show up early in childhood, while social phobia and panic disorder are often diagnosed during the teen years. Studies suggest that 3 - 5% of children and adolescents have some anxiety disorder. Children and adolescents who have an anxiety disorder are at risk of later developing other anxiety disorders, depression, and substance abuse.

Personality Factors. Children's personalities may indicate higher or lower risk for future anxiety disorders. For example, research suggests that extremely shy children and those likely to be the target of bullies are at higher risk for developing anxiety disorders later in life. Children who cannot tolerate uncertainty tend to be worriers, a major predictor of generalized anxiety. In fact, such traits may be biologically based and due to a hypersensitive amygdala -- the "fear center" in the brain.

Family History and Dynamics. Anxiety disorders tend to run in families. Genetic factors may play a role in some cases, but family dynamics and psychological influences are also often at work.

Social Factors. Several studies have reported a significant increase in anxiety levels in children and college students in the past two decades compared to children in the 1950s. In several studies, anxiety was associated with a lack of social connections and a sense of a more threatening environment. It also appears that more socially alienated populations have higher levels of anxiety. For example, a study of Mexican adults living in California reported that native-born Mexican Americans were three times more likely to have anxiety disorders (and even more likely to be depressed) as those who had recently immigrated to the U.S. The longer the immigrants lived in the U.S., the greater their risk for psychiatric problems. Traditional Mexican cultural and social ties seemed to protect recently arrived immigrants from mental illness.

Genetic Factors. Up to 50% of people with panic disorder and 40% of patients with generalized anxiety (GAD) have close relatives with the disorder. (About half of GAD patients also have family members with panic disorder, and about 30% have relatives with simple phobias.)

Obsessive-compulsive disorder (OCD) is also strongly related to a family history of the disorder. Close relatives of people with OCD are up to 9 times more likely to develop OCD themselves. Researchers are making progress in identifying specific genetic factors that might contribute to an inherited risk. Of particular interest are genes that regulate specific neurotransmitters (brain chemical messengers), including serotonin and glutamate. Recent research has suggested that the SLC1A1 gene, which is associated with glutamate regulation, may play an important role in early-onset OCD in boys. Research is also beginning to pinpoint regions on specific chromosomes (1, 3, 7, 6, 9, 15) that may contain genes linked to OCD.

However, there are no genetic tests to date that can identify patients at risk for anxiety disorders.

Medical Conditions. Although no causal relationships have been established, certain medical conditions have been associated with panic disorder. They include migraines, obstructive sleep apnea, mitral valve prolapse, irritable bowel syndrome, chronic fatigue syndrome, and premenstrual syndrome.

GAD affects about 1 - 5% of Americans in the course of their lives and is more common in women than in men. Some experts believe that it is underdiagnosed and more common than any other anxiety disorder. It is certainly the most common anxiety disorder among the elderly. GAD usually begins in childhood and often becomes a chronic ailment, particularly when left untreated. Depression in adolescence may be a strong predictor of GAD in adulthood. Depression commonly accompanies this anxiety disorder in any case.

Age and Panic Disorder. Studies indicate that the prevalence of panic disorder among adults is between 1.6 - 2% and is much higher in adolescence, 3.5 - 9%. Panic disorder usually first occurs either in late adolescence or in the mid-30s.

Gender and Panic Disorder. Women have about twice the risk for panic disorder as men. Panic attacks are very common after menopause. In one study, nearly 18% of older women reported panic attacks within a 6-month period, with over half of these attacks being full-blown. They tended to be associated with stressful life events and poor health. The effects of pregnancy on panic disorder appear to be mixed. It seems to improve the condition in some women and worsen it in others.

Obsessive-compulsive disorder occurs equally in men and women, and it affects about 2 - 3% of people over a lifespan. Most cases of OCD first develop in childhood or adolescence, although the disorder can occur throughout the life span.

Social anxiety disorder is currently estimated to be the third most common psychiatric disorder in the U.S. Studies have reported a prevalence of 7 - 12% in Western nations.

Age and Phobias. The onset of social anxiety disorder is usually during the early teenage years.

Gender and Phobias. Women are more likely to develop social anxiety disorder than men, although equal numbers of men and women seek treatment for it. Most people seeking treatment have had symptoms for at least 10 years.

Studies estimate a lifetime risk for PTSD in the U.S. of up to 8%. People exposed to traumatic events, of course, are at highest risk, but many people can go through such events and not experience PTSD. Studies estimate that 6 - 30% or more of trauma survivors develop PTSD, with children and young people being among those at the high end of the range. Women have the twice the risk of PTSD as men.

Furthermore, PTSD can occur in people not directly involved with a traumatic event. For example, 17% of the U.S. population outside New York City reported some symptoms of post-traumatic stress 2 months after the September 11 attack on the World Trade Towers. (In the city itself, where the attack occurred, an estimated 7.5% of New York's population reported PTSD within the month of the event, which declined to 0.6% at 6 months.)

Researchers are trying to determine factors that might increase vulnerability to catastrophic events and put people at risk for develop PTSD. Some studies report the following may be risk factors:

Pre-existing emotional disorder. People who have a history of an emotional disorder, particularly depression, before the traumatic event are at higher risk for PTSD.
Drug or alcohol abuse
A family history of anxiety
A history of abuse, particularly that which threatens family integrity, such as spousal or child abuse. Studies of individuals who had suffered physical or sexual abuse or neglect as children suggest that up to one-third develop PTSD.
An early separation from parents
Lack of social support and poverty
Sleep disorders. Insomnia and excessive daytime sleepiness even within a month after a traumatic event are important predictors for the development of PTSD. One specific sleep disorder -- sleep apnea -- may even intensify symptoms of PTSD, including sleeplessness and nightmares. Sleep apnea occurs when tissues in the upper throat (or airway) collapse at intervals during sleep, thereby blocking the passage of air. In one study, 91% of crime victims with PTSD had either sleep apnea or a lesser condition that partially blocked the airways during sleep. In fact, in one study treatment of sleep apnea eased PTSD. Sleep apnea has also been associated with a risk for panic disorder. [For more information, see In-Depth Report #65: Sleep apnea.]

Complications

Studies consistently report that all types of anxiety disorders can be very debilitating and seriously affect a person’s quality of life.

Depression. Depression is very common in people with an anxiety disorder, and it is sometimes difficult to distinguish one from the other because either or both can be accompanied by anxious feelings, agitation, insomnia, and problems with concentration.

Depression and nearly every anxiety disorder often go hand in hand, in both the young and old. In fact, the lifetime risk for depression in people with anxiety disorders may be higher than 70%. Furthermore, the combination of depression and anxiety is a major risk factor for both substance abuse and suicide. The following are examples of depression in specific anxiety disorders:

Between 50 - 65% of people with panic disorder also have major depression. Some studies have suggested that treating panic disorder early enough may help prevent major depression later on.
More than two-thirds of OCD patients suffer from depression.
Most patients with GAD will experience at least one episode of significant depression and many develop recurrent episodes. In patients with both disorders, GAD usually precedes the onset of depression.
Social anxiety during adolescence or young adulthood has been associated with a higher risk for depression, and the presence of both increases the chances for severe depression.
People with PTSD are four to seven times as likely to be depressed as are people without PTSD.

Bipolar Disorder. Symptoms of panic disorder are very common in people with bipolar disorder (manic-depression). In fact, people with bipolar have 26 times the rate of panic disorder as in the general population. Furthermore, anxiety worsens bipolar disorder. According to one study, anxiety disorders in teenagers were associated with bipolar disorder in adulthood, while manic behavior in adolescence was linked to later anxiety disorders.

Evidence now strongly supports an association between panic disorder and a risk for suicidal thoughts. Studies report that up to 18% of people with panic disorder attempt suicide and up to 38.5% regularly harbor suicidal thoughts, with the risks being higher in people with both panic disorder and depression. One study reported suicide attempts in about 12% of people with social phobias or OCD. If a person has an anxiety disorder and a mood disorders (such as depression), the risk for suicide is even higher.

Suicide is the third most common cause of death among adolescents, and is one of the most devastating events than can happen to a family. Suicide is most commonly associated with depression in young people, but it is also commonly associated with anxiety, psychosis, substance abuse, or impulsivity. More girls attempt suicide but more boys succeed, most often because they choose guns or violent methods while girls tend to overdose, which is more treatable. Nevertheless, unsuccessful attempts are major risk factors for a later suicide. Any expression of suicidal intent should be treated very seriously.

The following are danger signs in young people:

Withdrawal from friends
Sudden decrease in school performance
Loss of interest in activities that were previously pleasurable
Unusual irritability
Unusual changes in sleep or eating habits

Risk factors for suicide include a history of neglect or abuse, history of deliberate self-harm, a family member who committed suicide (nearly always one who shared a common mood disorder), access to firearms, and living in communities where there have been recent outbreaks of suicide in young people. A romantic break-up is often the trigger for a suicidal attempt in teenagers. Feeling connected with parents and family protected young people with depression in one study, regardless of gender or ethnicity.

In one study, adolescents failed to seek help for suicidal thoughts for the following reasons:

They believed nothing would help.
They were reluctant to tell anyone they had problems.
They thought it was a sign of weakness to seek help.
They did not know where to go.

Parents should not hesitate to seek professional help for their children if they suspect they are thinking about killing themselves. This is a medical emergency and requires immediate treatment.

[For more information on suicide, see In-Depth Report #8: Depression.]

Severely depressed or anxious people are at high risk for alcoholism, smoking, and other forms of addiction. Anxiety disorders are highly prevalent among people with alcoholism. Moreover, long-term alcohol use can itself cause biologic changes that may actually produce anxiety and depression.

Risk for Substance Abuse in Specific Anxiety Disorders. The following are some observations on specific anxiety disorders and substance abuse:

Some people with GAD and panic disorders may use alcohol or drugs to self-medicate.
Social phobia appears to pose a particular risk for alcohol abuse. People with this disorder are likely to drink in order to boost confidence. Alcohol itself has no direct beneficial effect on anxiety, but studies suggest that the belief in its effect appears to relieve anxious feelings. (Alcohol or substance abuse is not associated with specific phobias -- such as a fear of flying or spiders.)
Heavy smoking and substance abuse are common in people with PTSD. In adolescents, the disorder not only increases the risk for drug and alcohol use but also for eating disorders.

Studies consistently report that anxiety disorders have negative effects on work and relationships. Some examples:

In one study, more than 10% of patients with GAD missed at least 6 days of work within the previous month.
In a survey of OCD sufferers, 40% reported that they had to stop working because of the disorder. Only 40% worked full-time, while only half were married.
A 2006 study indicated that children with OCD are more likely to be bullied than other children.
Studies report that people with social phobias are less likely to get married, to leave home, and to finish school than those without this disorder. Their outlook worsens if they have other emotional disorders.

Anxiety disorders are associated with many different physical illnesses. Research suggests that people who have both an anxiety disorder and a physical illness have a worse quality of life and greater risk for disability than those who have only a physical illness. Anxiety disorders often tend to occur before the development of physical disorders.

Heart Disease. Anxiety has been associated with several heart problems, including unhealthy cholesterol levels, thicker blood vessels, and high blood pressure. Both anxiety and depression have been associated with a poorer response to treatment in heart patients, including a worse outcome after heart surgery.

Cholesterol is a soft, waxy substance that is present in all parts of the body including the nervous system, skin, muscle, liver, intestines, and heart. It is made by the body and obtained from animal products in the diet. Cholesterol is manufactured in the liver and is needed for normal body functions including the production of hormones, bile acid, and vitamin D. Excessive cholesterol in the blood contributes to atherosclerosis and subsequent heart disease. The risk of developing heart disease or atherosclerosis increases as the level of blood cholesterol increases.

Some researchers speculate that intense anxiety might trigger abnormal and dangerous heart rhythms in people with existing heart problems. In other studies, panic disorders, post-traumatic stress disorder, and phobias have been associated with a higher rate of sudden death from cardiac events, including heart attack.

Gastrointestinal Disorders. Anxiety frequently accompanies gastrointestinal conditions. Of note, half the cases of irritable bowel syndrome are associated with anxiety.

Headache. Both tension and migraine headaches are associated with anxiety disorders. One study reported that 32% of people with chronic tension headaches met criteria for anxiety. Similarly, another study reported that young girls with anxiety disorders were three times more likely to have chronic headaches than those without the disorder. (Headaches in both studies were also strongly associated with depression.)

Respiratory Problems. Studies report an association between anxiety in patients with obstructive lung conditions (asthma, emphysema, and chronic bronchitis) and more frequent relapses.

Obesity. Anxiety disorders may lead to obesity, and the reverse may also be true. A 2006 study suggested that anxiety disorders and depression in childhood may lead to higher body mass index (BMI) in adult women (but not men). Another 2006 study indicated that obesity is associated with a 25% increased risk of developing anxiety and mood disorders.

Allergic Conditions. Anxiety disorders are associated with numerous allergic conditions including hay fever, eczema, hives, food allergies, and conjunctivitis.

Other Conditions. Other physical conditions associated with anxiety disorders include thyroid problems and arthritis.

People with obsessive-compulsive disorders can experience skin problems from excessive washing, injuries from repetitive physical acts, and hair loss from repeated hair pulling (behavior known as trichotillomania).

Effect of PTSD on the Brain. Studies are reporting that PTSD is associated with shrinkage in the hippocampus, the part of the brain important for memory and learning. Some animal studies indicate that such damage may result from long-term exposure to cortisol, the major stress hormone. In one study, people who had suffered severe trauma scored 40% lower in tests of verbal memory than did the general population. There was no difference in IQ or in scores of other types of memory. Some studies suggest that exposure to chronic stress, common in PTSD patients, may even compromise the function of the brain’s receptors for anti-anxiety medication. On the other hand, a small hippocampal volume may itself increase stress hormone levels, so people with genetically smaller hippocampi may be susceptible to PTSD.

Effects of PTSD on Health. Studies of military veterans who have endured major traumatic events have found a higher risk for health problems. One study of Vietnam veterans reported that PTSD was associated with greater physical limitations, poorer physical health, and a lower quality of life than was found in the general population, regardless of other accompanying emotional or medical disorders. In another study of these veterans, PTSD sufferers had twice the risk for abnormal heart rhythms and four times the risk of a heart attack compared to men without PTSD.

Evidence suggests an association between anxiety in children and recurrent stomach aches. Anxiety has been associated with a higher risk for sleep disorders in children, such as frequent nightmares, restless legs syndrome, and bruxism (grinding and gnashing of the teeth during sleep).

Diagnosis

A physical examination and medical and personal history is essential. Because anxiety accompanies so many medical conditions, some serious, it is extremely important for the doctor to uncover any medical problems or medications that might underlie or be masked by an anxiety attack.

The patient should describe any occurrence of anxiety disorders or depression in the family and mention any other contributing factors, such as excessive caffeine use, recent life changes, or stressful events.

It is very important to be honest with your doctor about all conditions, including excessive drinking, substance abuse, or other psychological or mood states that might contribute to, or result from, the anxiety disorder.

Diagnosing children with an anxiety disorder can be very difficult, since anxiety often results in disruptive behaviors that overlap with attention-deficit hyperactivity or oppositional disorder. Other conditions with symptoms similar to anxiety disorders include pervasive developmental disorders such Asperger syndrome, learning disabilities, bipolar disorder, and depression. Many children have anxiety disorder and a co-occurring condition, which should be treated along with anxiety.

People with anxiety disorders are more likely to see a family doctor before a mental health specialist, since their symptoms are often physical. Symptoms can include muscle tension, trembling, twitching, aching, soreness, cold and clammy hands, dry mouth, sweating, nausea or diarrhea, or urinary frequency. Anxiety attacks can mimic or accompany nearly every acute disorder of the heart or lungs, including heart attacks and angina (chest pain). In fact, nearly all individuals with panic disorders are convinced that their symptoms are physical and possibly life-threatening.

Heart Problems. Studies suggest that up to a third of patients entering the emergency room with chest pain and who are low-to-moderate risk for a heart attack are actually suffering from panic attacks. It is often difficult even for specialists to distinguish between heart conditions and a panic attack:

Women who are having an actual heart attack or acute heart problem are much more likely to be misdiagnosed as having an anxiety attack than are men with similar symptoms.
Mitral valve prolapse, a common and usually mild heart problem, may have symptoms that are nearly identical to those of panic disorder. The two conditions, in fact, frequently occur together.

Mitral valve prolapse is a disorder in which the mitral valve does not close properly when the heart contracts. When the valve does not close properly it allows blood to backflow into the left atrium. Some symptoms can include palpitations, chest pain, difficulty breathing after exertion, fatigue, cough, and shortness of breath while lying down.

People with a heart-rhythm disturbance called paroxysmal supraventricular tachycardia have many of the same symptoms as those with panic attacks.

Asthma. Asthma attacks and panic attacks have similar symptoms and can also coexist.

Hyperthyroidism. Hyperthyroidism can cause many of the same symptoms of generalized anxiety disorder and must be ruled out.

Click the icon to see an image of hyperthyroidism.

Epilepsy. The symptoms of partial seizures and panic attacks often overlap.

Other Medical Conditions. In addition, anxiety-like symptoms are seen in many other medical problems, including hypoglycemia, recurrent pulmonary emboli, and adrenal-gland tumors. Women can also experience intense anxiety attacks with hot flashes during menopause.

Medication Side Effects. Many drugs, including some for high blood pressure, diabetes, and thyroid disorders, can produce symptoms of anxiety. Withdrawal from certain drugs, often those used to treat sleep disorders or anxiety, can also precipitate anxiety reactions.

Substance Abuse. People with anxiety disorders often drink alcohol or abuse drugs in order to conceal or eliminate symptoms, but substance abuse and dependency can also cause anxiety. In addition, withdrawal from alcohol can produce physiologic symptoms similar to panic attacks. Clinicians often have difficulty determining whether alcoholism or anxiety is the primary disorder. Overuse of caffeine or abuse of amphetamines can cause symptoms resembling a panic attack.

Clinicians use various screening tests to determine the causes, type, severity, and frequency of anxiety. Such tests include the Hamilton Anxiety Rating Scale, the Beck Anxiety Inventory, the Penn State Worry Questionnaire, and the Yale-Brown Obsessive Compulsive Scale.

Treatment

Anxiety disorders require treatment. Simply trying to talk oneself out of anxiety is as futile as trying to talk oneself out of a heart or stomach problem. Most anxiety disorders, especially phobias, respond well to treatment. They may, however, require long-term treatment. Many patients have a recurrence and may require additional medications. Nevertheless, most patients do not receive appropriate care for anxiety disorders. Many patients do not receive any treatment at all.

The standard current approach to most anxiety disorders is a combination of cognitive-behavioral therapy (CBT) and an antidepressant medication. A selective serotonin reuptake inhibitor (SSRI) is typically the first choice, with the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine (Effexor) an alternative. If patients do not respond to these drugs, tricyclic antidepressants or monoamine oxidase inhibitors (MAOIs) may be helpful. Benzodiazepines may be recommended for patients who are not helped by antidepressants. A healthy lifestyle that includes exercise, adequate rest, and good nutrition can also help to reduce the impact of anxiety.


Anxiety Disorder	Medications	Cognitive-Behavioral Therapy (CBT) and other Non-Drug Therapies
Generalized Anxiety Disorder	Antidepressants, benzodiazepines, and buspirone are helpful but have varying side effects. Investigational drugs include pregabalin and other anticonvulsants.	Cognitive-behavioral therapy or anxiety management therapy. Anxiety management therapy involves education, relaxation training, and exposure to anxiety-provoking stimuli but does not include cognitive restructuring.
Panic Attacks	SSRIs are treatment of choice. If patients do not respond to SSRIs, short-term treatment with a benzodiazepine may be used, or patients may switch to another type of antidepressant such as venlafaxine or tricyclics.	Cognitive-behavioral therapy, provided in 12 - 16 sessions over 3 - 4 months, focuses on recreating fear symptoms and helping patients change their response to them.
Social Anxiety Disorder	SSRIs or venlafaxine are first-line drug treatments. Benzodiazepines may help patients who do not respond to these antidepressants. In severe cases, an MAOI antidepressant may be prescribed. Anticonvulsants such as gabapentin (Neurontin) and pregabalin (Lyrica) are being investigated.	Cognitive-behavioral therapy can help improve symptoms after 6 - 12 weeks.
Obsessive-Compulsive Disorder	SSRIs are the first choice for adults. Clomipramine (a tricyclic antidepressant) is an alternative for adult patients who do not respond to SSRIs. For children, SSRIs do not seem to work as well for OCD as for other types of anxiety disorders.	Cognitive-behavioral therapy is the first treatment choice for children. For adults, either CBT or drug therapy may be offered as initial treatment. CBT techniques focus on exposure and response prevention (ERP).
Post-Traumatic Stress Disorder	Antidepressants, particularly SSRIs (sertraline and paroxetine approved for PTSD). The atypical antipsychotic olanzapine may be added to an antidepressant for patients who do not respond to a SSRI alone.	Trauma-focused psychological treatments include exposure therapy, trauma-focused cognitive therapy, and eye movement desensitization and reprocessing.
Note: For anxiety disorders in adults, the most effective treatments are usually combinations of drugs and CBT techniques. For children, CBT is usually the first treatment.

Medications

Selective serotonin-reuptake inhibitors (SSRIs), or the serotonin-norepinephrine reuptake inhibitor (SNRI) venlafaxine (Effexor), are the primary first-line treatment for anxiety disorders. For patients who are not helped by these drugs, benzodiazepines, either alone or in combination with an antidepressant, may be prescribed. Other types of antidepressants, including tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs), may also be used to treat patients with severe or chronic forms of anxiety disorders.

Drug therapies for anxiety disorders work best in combination with cognitive behavioral therapy.

Selective Serotonin Reuptake Inhibitors (SSRIs). SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), fluvoxamine (Luvox), citalopram (Celexa), and escitalopram (Lexapro).

SSRIs can cause agitation, nausea, and diarrhea. Sexual function side effects include low sex drive, inability to have an orgasm, and impotence. Over time, many SSRI-treated patients gain weight, although the degree of weight gain varies depending on the drug. Elderly people taking these drugs should take the lowest effective dose possible, and those with heart problems should be monitored closely.

There have been many concerns about SSRIs and increased risk for suicidal behavior. Both adults and children who are treated with SSRIs should be carefully monitored for any worsening of depressive symptoms or changes in behavior. This is especially important during the first few months of antidepressant treatment.

Paroxetine has been linked to heart-related birth defects when women took this drug during the first trimester of pregnancy. Experts are also advising caution in prescribing other types of SSRIs to pregnant women. While certain SSRIs may carry increased risks for some specific type of rare birth defects, research suggests that the overall risks are minimal. Still, women who are pregnant or who are considering becoming pregnant should discuss the potential risks of these drugs with their doctors.

Serotonin-norepinephrine reuptake inhibitors (SNRIs). SNRIs are known as dual inhibitors because they work on two neurotransmitters -- norepinephrine and serotonin. Venlafaxine (Effexor) is an SNRI that is approved for treatment of generalized anxiety disorder, social anxiety disorder, and panic disorder in adults. (It is not approved for children.) As with many SSRIs, venlafaxine impairs sexual function. Venlafaxine can increase blood pressure and heart rate and should be used with caution in patients with high blood pressure or heart disease. Some patients report severe withdrawal symptoms, including dizziness and nausea. This drug has a serious risk for overdose. Venlafaxine should not be taken during the last trimester of pregnancy because the drug can cause complications in newborn infants.

Duloxetine (Cymbalta) also acts on both serotonin and norepinephrine. In 2007, it was approved for treatment of generalized anxiety disorder. Side effects are generally mild and include dry mouth, nausea, and sleepiness. Patients with narrow-angle glaucoma or patients with liver or kidney diseases should not take duloxetine. Because duloxetine can cause liver damage, patients who drink large quantities of alcoholic beverages should not take it.

Mitrazapine (Remeron) is another type of SNRI that is sometimes used for treatment of post-traumatic stress disorder and social anxiety disorder.

Tricyclic Antidepressants. Tricyclics are an older type of antidepressant. Tricyclics used for treatment of anxiety disorder include imipramine (Tofranil, for generalized anxiety disorder, panic disorder), nortriptyline (Pamelor, for panic disorder), desipramine (Norpramin, for panic disorder), and clomipramine (Anafranil, for obsessive compulsive disorder). Clomipramine is approved specifically for OCD, but because of its severe side effects it is usually used only if SSRIs have failed to help.

Side effects of TCAs include sleep disturbance, abrupt reduction in blood pressure upon standing, weight gain, sexual dysfunction, and mental disturbance. Elderly patients and those with a history of seizures, cardiac problems, closed-angle glaucoma, and urinary retention or obstruction should be closely supervised when taking tricyclics.

Monoamine Oxidase Inhibitors. Monoamine oxidase inhibitors (MAOIs) are the oldest type of antidepressant. The MAOI phenelzine (Nardil) is sometimes used to treat social anxiety disorder or post-traumatic stress disorder that has not responded to other treatments.

MAOIs commonly cause weight gain, drowsiness, dizziness, sexual dysfunction, and insomnia. Dietary restrictions are the main problem with these drugs. Severe high blood pressure (hypertension) can be brought on by eating certain foods that have a high tyramine content, including cheese, red wine, and processed meats. High blood pressure can also occur when MAOIs are taken with certain drugs, including some common over-the-counter cough medications and decongestants. MAOIs can cause birth defects and should not be taken by pregnant women.

Most serious, fatal reactions can occur when MAOIs and SSRIs or venlafaxine are taken at the same time. There should be at least a 2- to 5-week break if a patient is changing from one type of antidepressant to the other.

Benzodiazepines are safe and effective medications for most anxiety disorders and have been the standard of treatment for years. However, their on-going use has been associated with a high risk for dependency and abuse. Therefore, they have been supplanted in most cases by SSRIs and other newer antidepressants. For anxiety disorders, benzodiazepines are most often used to treat panic disorder, and are sometimes used for social anxiety disorder and generalized anxiety disorder. These drugs include alprazolam (Xanax), clonazepam (Klonopin), and lorazepam (Ativan).

Benzodiazepines have many side effects, generally associated with chronic use. The most common are daytime drowsiness and a hung-over feeling. In rare cases, they can cause agitation. They may worsen respiratory problems. Benzodiazepines are potentially dangerous when used in combination with alcohol. Overdoses can be serious, although they are very rarely fatal.

The elderly are more susceptible to side effects and should usually start at half the dose prescribed for younger people. These drugs increase the risk of falling, which can increase the risk for hip fracture in older people. Also of concern are studies showing a high risk of automobile accidents in people who take benzodiazepines. Benzodiazepines taken during pregnancy are associated with birth defects, and they should not be used by pregnant women or by nursing mothers.

Loss of Effectiveness and Dependence. Eventually these drugs can lose their effectiveness with continued use at the same dosage. As a result, patients may want to increase their dosage to prevent anxiety. This causes dependency, which can occur after taking these drugs for several weeks.

Withdrawal and its Treatments. Withdrawal symptoms can be very severe, even in people who rapidly discontinue benzodiazepines after taking them for only 4 weeks. Symptoms include sleep disturbance and anxiety, which can develop within hours or days after stopping the medication. Some patients experience stomach distress, sweating, and insomnia, which can last 1 - 3 weeks. The longer the drugs are taken and the higher their dose, the more severe these symptoms can become. Simply tapering off gradually helps about 60% of people stop taking these drugs. Certain medications (anti-seizure drugs, antidepressants, buspirone) may also help with withdrawal.

Azapirones, such as buspirone (BuSpar), act on serotonin receptors called 5-HT(1A). Buspirone appears to work as well as a benzodiazepine for treating generalized anxiety disorder. It usually takes several days to weeks for the drug to be fully effective. It is not useful against panic attacks.

Buspirone does not produce any immediate euphoria or change in sensation, so some people believe, erroneously, that the drug doesn't work. Such qualities result in a very low potential for abuse. In fact, unlike the benzodiazepines, buspirone is not addictive, even with long-term use, so it may be particularly useful for the patient whose anxiety disorder coexists with alcoholism or drug abuse.

Buspirone also seems to have less pronounced side effects than benzodiazepines and no withdrawal effects, even when the drug is discontinued quickly. Common side effects include dizziness, drowsiness, and nausea. Buspirone should not be used with monoamine oxidase inhibitors (MAOIs).

Beta-blockers, including propranolol (Inderal) and atenolol (Tenormin), block the nerves that stimulate the heart to beat faster. They affect only the physiologic symptoms of anxiety (particularly rapid heart rate) and are most helpful for phobias, particularly performance anxiety. They may be taken before entering a situation where anxiety symptoms tend to occur. Beta-blockers are less effective for other forms of anxiety.

Atypical antipsychotics are mostly used for treating schizophrenia, bipolar disorder, and major depressive disorder. Doctors sometimes use the atypical antipsychotic olanzapine (Zyprexa) for treating severe cases of post-traumatic stress disorder. However, olanzapine has severe side effects, including weight gain and increased high blood sugar levels, which can increase the risk for diabetes. [For more information, see In-Depth Report #47: Schizophrenia.]

Pregabalin (Lyrica) and gabapentin (Neurontin) are drugs used to treat seizures and other conditions. Researchers are investigating whether these drugs may be useful for certain anxiety disorders, such as social anxiety disorder and general anxiety disorder. Their exact role in the treatment of anxiety disorders is not clear, however.

Generally, manufacturers of herbal remedies and dietary supplements do not need FDA approval to sell their products. Just like a drug, herbs and supplements can affect the body's chemistry, and therefore have the potential to produce side effects that may be harmful. There have been a number of reported cases of serious and even lethal side effects from herbal products. Always check with your doctor before using any herbal remedies or dietary supplements.

Studies indicate that the dietary supplement inositol may have benefits for panic disorder and, possibly, obsessive compulsive disorder. Inositol is part of the vitamin B complex.

Some patients use aromatherapy as a relaxation aid. Aromatherapy is in general safe, but some plant extracts in these formulas have been linked to skin allergies.

There is no evidence supporting the efficacy of valerian, St. John’s wort, or passionflower for treatment of anxiety. The herbal remedy kava has been associated with liver problems and should not be avoided, especially by patients with liver disease or those who use alcohol. Kava can also interact dangerously with medications that are metabolized by the liver.

Other Treatments

The goal of cognitive-behavioral therapy (CBT) is to regain control of reactions to stress and stimuli, thus reducing the feeling of helplessness that often accompanies anxiety disorders. CBT works on the principle that the thoughts that produce and maintain anxiety can be recognized and altered using various techniques that change behavioral responses and eliminate the anxiety reaction. Many studies have shown that a combination of CBT and medication works best for treating anxiety disorders.

A number of CBT approaches work well for treating many types of anxiety disorders. Studies suggest that CBT is also helpful for patients who have additional conditions, such as depression, a second anxiety disorder, or alcohol dependency. (It may take longer to achieve a successful outcome in such cases, however.) CBT is often given along with drug treatment. A study in the Journal of the American Medical Association found that children and adolescents with OCD responded better to CBT alone than the antidepressant setraline (Zoloft) alone, but most patients did best when they were treated with a combination of CBT and sertraline.

Both individual and group treatments work well. (However, people with social phobia may do better in individual sessions.) Several recent studies also indicate that telephone-based behavioral therapy works well for people with OCD, generalized anxiety disorder, and panic disorders.

Anxiety disorders are chronic, however, and recurrence is common. Some studies indicate that 30 - 82% of people with panic disorder and phobias have a recurrence of attacks at an average of 9 months, even after successful short-term therapy. Medications, then, are also generally recommended for most patients.

Basic Cognitive Therapy Techniques. Treatment usually takes about 12 - 20 weeks. The essential goal of cognitive therapy is to understand the realities of an anxiety-provoking situation and to respond to reality with new actions based on reasonable expectations.

First, the patient must learn how to recognize anxious reactions and thoughts as they occur. One way of accomplishing this is by keeping a daily diary that reports the occurrences of anxiety attacks and any thoughts and events associated with them. A patient with OCD, for instance, may record repetitive thoughts.
These entrenched and automatic reactions and thoughts must be challenged and understood. Again, using the OCD example, one approach is to record and play back the words of the repetitive thoughts, over exposing the patient to the thoughts and reducing their effect. One effective approach for patients with generalized anxiety disorder targets their intolerance of uncertainty and helps them develop methods to cope with it.
Patients are usually given behavioral homework assignments to help them change their behavior. For example, a person with generalized social phobia may be asked to buy an item and then return it the next day. As the patient performs this action, they observe any unrealistic fears and thoughts triggered by such an event.
As the patient continues with self-observation, they begin to perceive the false assumptions that underlie the anxiety. For example, OCD patients may learn to recognize that their heightened sense of responsibility for preventing harm in non-threatening situations is not necessary or even useful.
At that point, the patient can begin substituting new ways of coping with the feared objects and situations.

Systematic Desensitization. Systematic desensitization is a specific technique that breaks the link between the anxiety-provoking stimulus and the anxiety response. This treatment requires the patient to gradually confront the object of fear. There are three main elements to the process:

Relaxation training
A list composed by the patient that prioritizes anxiety-inducing situations by degree of fear
The desensitization procedure itself, confronting each item on the list, starting with the least stressful

This treatment is especially effective for simple phobias, social phobias, agoraphobia, and post-traumatic stress syndrome.

Exposure and Response Treatment. Exposure treatment purposefully generates anxiety by exposing the patient repeatedly to the feared object or situation, either literally or using imagination and visualization. It uses the most fearful stimulus first. (This differs from the desensitization process because it does not involve relaxation or a gradual approach to the source of anxiety.)

Exposure treatments are usually known as either flooding or graduated exposure:

Flooding exposes the person to the anxiety-producing stimulus for as long as 1 - 2 hours.
Graduated exposure gives the patient a greater degree of control over the length and frequency of exposures.

In both cases, the patient experiences the anxiety over and over until the stimulating event eventually loses its effect. Combining exposure with standard cognitive therapy may be particularly beneficial. This approach has helped certain patients in most anxiety disorder categories, including post-traumatic stress disorder.

Modeling Treatment. Phobias can often be treated successfully with modeling treatment:

The therapy typically uses an actor who approaches an anxiety-producing object or engages in a fear-provoking activity that is similar to the patient's specific problem. Either a live or videotaped situation may be used, although the live model is considered to be more effective.
The patient observes this event and tries to learn how to behave in a comparable manner.

Other forms of psychotherapy, commonly called emotion-based psychotherapy (EBT), psychodynamic therapy, or "talk" therapy, deal more with childhood roots of anxiety and usually, although not always, require longer treatments. They include interpersonal therapy, supportive psychotherapy, attention intervention, and psychoanalysis. All work is done during the sessions. Some research indicates that such therapies might be more useful for generalized anxiety, which may require more sustained work to process and recover from early traumas and fears. Studies suggest that although emotion-based psychotherapies are not as effective as cognitive-behavioral therapy (CBT) in treating panic disorders, patients tend to stay longer in EBT than in CBT. Some doctors suggest adding elements of EBT to the usual CBT and medication treatments.

Anxiety Management Therapy. Anxiety management therapy is sometimes used as an alternative to CBT for generalized anxiety disorder. It involves patient education, relaxation training, and exposure to anxiety-provoking stimuli but does not include exercises in cognitive retraining.

Relaxation Training. Relaxation techniques use muscle relaxation and mental visualization to help focus attention towards a calming feeling. Some people find meditation helpful.

Breathing Retraining. Breathing retraining techniques may help reduce the physical effects of anxiety. For example, hyperventilation is one of the primary physical manifestations of panic disorders. This involves rapid, tense breathing, resulting in chest pain, dizziness, tingling of the mouth and fingers, muscle cramps, and even fainting. By practicing measured, controlled breathing at the onset of a panic attack, patients may be able to prevent full attacks.

Biofeedback. Biofeedback uses special sensors that allow patients to recognize anxiety states by changes in specific physical functions, such as changes in pulse rate, skin temperatures, and muscle tone. Eventually they learn to modify these changes, which in turn helps relieve anxiety. While commonly used, there are not many rigorous studies showing that biofeedback helps patients reduce or eliminate their symptoms over the long term.

Several types of psychological treatments have been designed specifically for treating patients with PTSD. These approaches include a special type of CBT known as trauma-focused cognitive behavioral therapy (TFCBT), and a psychotherapy treatment called eye movement desensitization and reprocessing (EMDR).

With TFCBT, patients are taught stress management skills. The therapist helps the patient develop a narrative (verbal, written, or artistic) about the traumatic event. Patients may be exposed to reminders about the trauma and are taught how to cope with future reminders. Through the process, the patient learns how to reprocess their thoughts, feelings, and behaviors.

With EMDR, the patient focuses on remembering the traumatic experience while visually following the rhythmic movement of the therapist’s fingers. The patient recounts to the therapist what memories have been provoked during the exercise. EMDR may help patients recall details and sensations that they had blocked out. Through this breakthrough, patients learn how to regain emotional control.

Transcranial magnetic stimulation (TMS) uses high frequency magnetic pulses to target and stimulate specific areas of the brain. Research has particularly focused on possible benefits for obsessive-compulsive behavior. Some studies have found some improvement in mood, but more research is needed to determine its value for reducing anxiety and obsessions.

In 2006, the U.S. National Institutes of Health funded a large study to examine whether deep brain stimulation (DBS) can help patients with OCD. DBS involves implanting tiny stimulators into the brain to block abnormal nerve signals that cause obsessive symptoms. These “brain pacemakers” are approved to treat epilepsy and Parkinson’s disease. Researchers hope that DBS may eventually provide a new treatment option for patients with severe OCD.

A surgical technique called cingulotomy involves interrupting the cingulate gyrus, a bundle of nerve fibers in the front of the brain. It is sometimes used as a last resort for patients with severe OCD. A variation of this procedure using magnetic resonance imaging (MRI) to guide the surgeon has resulted in long-term improvement in about 25 - 33% of OCD patients in whom it is performed. The procedure is generally safe with few serious complications and does not affect intellect or memory.

Colorectal cancer -- cancer of the colon and rectum -- is the second most commonly diagnosed cancer in American men and women. Colorectal cancer develops in the digestive system, which processes food for energy and rids the body of solid waste. Together, the colon and rectum form a muscular tube about 5 feet long known as the large intestine. The colon (the first and largest part of the large intestine) absorbs water and nutrients from food and serves as a storage place for solid waste. The waste moves from the colon into the rectum (the final 6 inches of the large intestine) where it passes out of the body through the anus. Cancers affecting either of these organs are called colorectal cancer. Most colorectal cancers arise from benign polyps (abnormal masses of tissue) that begin growing on the inner lining of the colon or rectum. These growths spread very slowly, taking from 10 - 20 years to become cancerous. Once colorectal cancer is diagnosed, the prognosis depends on how far the cancer has spread.

The American Cancer Society estimates that about 150,000 cases of colorectal cancer are diagnosed every year in the United States. Most cases of colorectal cancer occur in people older than 50 years of age. Although colorectal cancer is expected to be responsible for about 56,000 deaths this year, the death rate from this form of cancer has been dropping steadily for the past 15 years. Some researchers speculate that the lowering death rate is due to prevention and early treatment of the disease.

Signs and Symptoms

Unfortunately, most people with colorectal cancer will not begin to experience symptoms until the disease is already at a late stage. In fact, some people may experience no symptoms at all. This is the reason that screening tests, such as a colonoscopy, are so important.

In general, signs and symptoms of colorectal cancer can include the following:

Changes in bowel habits
Blood in the stool
Problems related to blood loss (anemia, weakness, fatigue, shortness of breath, pounding or racing heart, chest pain, and intolerance to exercise)
Abdominal discomfort (frequent gas, bloating, fullness, cramps, and pain)
Unexplained weight loss
Pain with defecation
Stools that are narrower than usual
Urgent desire to defecate (and the passage of little matter)

These symptoms may be caused by colorectal cancer or by other conditions such as infections, hemorrhoids, and inflammatory bowel disease. It is important to bring any of these symptoms to the attention of your health care provider to determine the cause of your symptoms.

Causes

Although more than half of all colorectal cancers occur without any clear cause, studies suggest that genetic factors may play an important role in the development of the disease. For example, many people with colorectal cancer carry specific genetic mutations (genes that normally suppress cancer growth are mutated and actually promote cancer growth) or have relatives with the condition. Those with a family history of specific genetic syndromes -- such as familial adenomatous polyposis, Lynch syndrome, juvenile polyposis, and Peutz-Jeghers syndrome -- are also at an increased risk for developing colorectal cancer. Dietary and lifestyle factors, such as smoking and high-fat intake, also influence the development of colorectal cancer. Some researchers speculate that genetic factors predispose a person to colorectal cancer, but that dietary and lifestyle factors play a strong role in determining which "at-risk" individuals go on to develop the disease.

Risk Factors

Family history of colorectal cancer or polyps in the colon
Older age (over 50 years)
Living in an industrialized country like the United States
Polyps on the inner lining of the colon or rectum
African-American descent
Diets high in meat and low in fruits and vegetables
Overweight or obesity
Regular consumption of alcohol
Smoking cigarettes regularly
Inflammatory bowel disease (such as irritable bowel syndrome, Crohn's disease, and ulcerative colitis)

Diagnosis

After obtaining a complete medical history, a health care provider will perform a physical exam and may order one or more tests to diagnose colorectal cancer. As mentioned in the Preventive Care section, standard tests used to diagnose colorectal cancer include the sigmoidoscopy, colonoscopy, and barium enema. At the time of either a sigmoidoscopy or a colonscopy, a biopsy (sample of tissue) is removed from the colon or rectum and examined under a microscope in order to detect abnormal growths. If the doctor finds cancer, a series of tests (chest x-ray, abdominal CT scan, and blood tests to check liver function) will be performed to determine if the cancer has spread and to help determine the stage (or extent) of the disease. Stages of colorectal cancer include:

Stage A: The earliest stage; cancer is found only in the innermost lining of the colon and/or rectum.
Stage B1: Involves the muscular part of the colon and/or rectum.
Stage B2: Cancer has spread to deeper layers of the wall of the colon and/or rectum.
Stage C: Cancer has spread to nearby lymph nodes but not to other parts of the body.
Stage D: Cancer has spread to other parts of the body, such as the liver and lungs.

Preventive Care

Screening

Colorectal cancer is highly preventable, even curable, when detected early. Regular screening for colorectal cancer helps detect the presence of polyps before they become cancerous. The American Cancer Society recommends the following standard screening practices for individuals who are not at high risk for colorectal cancer and who have no symptoms of the disease:

Annual digital rectal exams starting at age 40: The doctor inserts a lubricated, gloved finger into the rectum to feel for abnormal areas.
Annual fecal occult blood tests starting at age 50: Stool samples are tested in the doctor's office for the presence of hidden blood.
Visualization of the colon via one of the following:
- Sigmoidoscopy (examination of the rectum and lower colon using a lighted instrument)
- Colonoscopy (examination of the rectum and entire colon using a lighted instrument)
- Barium enema (examination using a series of x-rays that reveal barium-stained outlines of the colon and rectum) every 3 -5 years starting at age 50

Those with a family history of colorectal cancer should undergo colonoscopy every 3 - 5 years, starting at least 10 years before the age of the relative at the time of his or her diagnosis. Those with a family history of familial adenomatous polyposis (a condition causing thousands of polyps along the inner lining of the colon) or other similar genetic syndromes (listed under Causes) should start having colonoscopies at age 10.

Diet and Exercise

People may also lower their chances of developing colorectal cancer by managing the risk factors they can control, such as diet and exercise. For example, eating plenty of fruits and vegetables as well as foods rich in omega-3 fatty acids (such as salmon and halibut) and calcium (such as sea vegetables and kale) can help reduce the risk of colorectal cancer. Limiting alcohol consumption, quitting smoking, and reducing the intake of high-fat and fried foods, particularly red meats, may also protect developing colorectal cancer.

Physical activity also will decrease the risk factors associated with developing colorectal cancer. Obesity and a sedentary lifestyle increases the risk of colorectal cancer. Even small amounts of exercise on a regular basis can be helpful, and the American Cancer Society recommends at least 30 minutes of physical activity on most days.

Other Preventive Measures

Preliminary studies also suggest that aspirin may prevent tumor growth and that hormone replacement therapy (HRT) may reduce the risk of colorectal cancer in women. However, HRT may increase the chances of developing other cancers, such as breast and ovarian. It is recommended to choose diet and lifestyle changes along with dietary supplements to protect against the risk factors associated with colorectal cancer.

Treatment

Surgery to remove the tumor is the only way to cure the disease, and early detection is the best preparation for successful treatment. Depending on the stage of the cancer, surgery is generally followed with chemotherapy. If the tumor is particularly large, radiation may be necessary before or after surgery.

Certain medications or supplements may help prevent the development of polyps and/or colorectal cancer. Modifying lifestyle, particularly avoiding red meat, losing weight, quitting smoking, and increasing physical activity, may help prevent the disease -- even in individuals with a family history of the condition.

Lifestyle

An unhealthy lifestyle may increase the risk of colorectal cancer even in people who have no family history of the condition. Some experts believe that adjusting lifestyle habits may decrease the likelihood of developing colorectal cancer by as much as 70% in some individuals.

Findings from studies support the association between colorectal cancer and physical inactivity and obesity. Research continues to point to the idea that exercise and low-calorie diets can help to prevent colorectal cancer.

A large, population-based study of men and women in Hawaii found that the following lifestyle factors were linked with colorectal cancer:

Smoking
Alcohol consumption
History of diabetes
Frequent constipation
High-calorie diet
Obesity
Physical inactivity
Low vegetable fiber intake (this association is controversial)
High levels of insulin (hormone that controls blood sugar levels)
Meat consumption

Medications

After surgery, chemotherapy (the use of anticancer drugs to destroy cancer cells) may be given to kill any cancerous cells that remain in the body. Chemotherapy controls the spread of the disease and improves survival rates over time. The following chemotherapeutic medications are used alone or in combination to treat colorectal cancer:

Fluorouracil (5-FU) -- often used in combination with leucovorin for 6 months after surgery. Reduces the rate of recurrence and improves chances of survival. Common side effects include nausea, diarrhea, inflammation of the skin and lining of the mouth, and lowered white blood cell count, which increases the chance of developing an infection and anemia.
Leucovorin -- a form of folic acid often used in combination with 5-FU. Side effects are rare but can include rash, itching, and wheezing.
Levamisole -- can be used in combination with 5-FU. Potential side effects are numerous and include nausea, vomiting, diarrhea, loss of appetite, abdominal pain, lower extremity swelling, insomnia, fatigue, headache, hair loss, dizziness, muscle and joint paints, and depression.

For colorectal cancer that has metastasized, or spread, doctors generally use 5-FU in combination with other drugs. One regimen approved by the United States Food and Drug Administration for metastatic colorectal cancer is 5-FU, leucovorin, and irinotecan. With the addition of irinotecan, the progression of the disease significantly slowed and survival improved compared to the 5-FU-leucovorin combination. However, an unexpectedly high death rate in two recent studies by the National Cancer Institute has brought the addition of irinotecan into question. There are other medications currently under investigation for metastatic colon cancer.

Long-term use of aspirin, other nonsteroidal anti-inflammatory drugs (NSAIDs), and hormone replacement therapy have shown promise in the prevention and treatment of colorectal cancer.

Aspirin -- may reduce the risk of polyps and colorectal cancer by up to 44%.
NSAIDs -- reduced the number of polyps by 90% and colon tumors by 55% in animals.
Hormone-replacement therapy (HRT) -- over the past 20 years, the rate of death from colorectal cancer among women has decreased far more than the rate among men. Studies suggest that this may be due to the increasing use of hormone-replacement therapy by women after menopause. However, HRT is not without risks, and your health care provider will help you determine which treatment is best for you.

Surgery and Other Procedures

Surgery is the treatment of choice for colorectal cancer, and is best when the disease is detected at an early stage. Before becoming cancerous, polyps can be removed during a colonoscopy. Depending on the severity and location of the cancer, including whether or where it has spread, an individual may need a partial or total removal of the colon (colectomy) and rectum (rectal resection). During surgery, the surgeon also examines other abdominal organs for signs of cancer. If cancer has spread to the liver, a portion of this organ may be removed as well. After removing the tumor and nearby tissue, the surgeon reconnects the healthy portions of the colon or rectum. If the healthy portions of the colon or rectum cannot be reconnected, a temporary or permanent opening (stoma) is made through the wall of the abdomen into the colon to provide a new path for waste material to leave the body. This procedure is called a colostomy. Radiation may also be used before or during surgery (called intraoperative radiotherapy) to shrink the tumor, and it may be recommended following surgery for certain stages of colorectal cancer to reduce the risk of recurrence. Following surgery, colonoscopies are performed every 3 - 6 months for 3 years to detect recurrence.

Nutrition and Dietary Supplements

A comprehensive treatment plan for colorectal cancer may include a range of complementary and alternative therapies. Nutrients and herbs may protect against side effects from conventional therapies as well as enhance chemotherapy and support anticancer activities. Mind-body therapies such as meditation, relaxation techniques, yoga, and qi gong may reduce the effects of stress and enhance your quality of life and your response to treatment. Ask your team of health care providers about the best ways to incorporate these therapies into your overall treatment plan.

Always tell your health care provider about the herbs and supplements you are using or considering, as some supplements may interfere with conventional cancer treatments.

Following these nutritional tips may help reduce symptoms:

Try to eliminate potential food allergens, including dairy, wheat (gluten), corn, preservatives, and food additives. Your health care provider may want to test for food sensitivities.
Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes), and vegetables (such as squash and bell peppers).
Eat foods high in B-vitamins and calcium, such as almonds, beans, whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables.
Avoid refined foods such as white breads, pastas, and especially sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein. Quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes, should be used as part of balanced program aimed at gaining muscle mass and preventing wasting that can sometimes be side effects of cancer therapies.
Use healthy oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily.
Exercise at least 30 minutes daily, 5 days a week.

You may use nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-complex vitamins, and trace minerals such as magnesium, calcium, zinc, and selenium.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 - 3 tablespoonfuls oil daily, to help decrease inflammation and help with immunity. Cold-water fish, such as salmon or halibut, are good sources.
Vitamin C, 500 - 1,000 mg, one to three times daily, as an antioxidant and for immune support.
L-glutamine, 500 - 1,000 mg three times daily, for support of gastrointestinal health and immunity.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, when needed for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
Grapefruit seed extract (Citrus paradisi), 100 mg capsule or 5 - 10 drops (in favorite beverage) three times daily when needed, for antibacterial, antifungal, and antiviral activity, and for immunity.
Astaxanthin, 2 - 6 mg daily, for immune and antioxidant support.
Alpha-lipoic acid, 25 - 50 mg twice daily, for antioxidant support.
Resveratrol (from red wine), 50 - 200 mg daily, to help decrease inflammation and for antioxidant effects.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant and immune activity.
Melatonin, 2 - 6 mg at bedtime as needed, for immune support and sleep. Higher doses may be needed in cancer. Consult your health care provider.

Herbs are generally a safe way to strengthen and tone the body's systems. As with any therapy, you should work with your health care provider to get your problem diagnosed before starting any treatment. You may use herbs as dried extracts (capsules, powders, teas), glycerites (glycerine extracts), or tinctures (alcohol extracts). Unless otherwise indicated, you should make teas with 1 tsp. herb per cup of hot water. Steep covered 5 - 10 minutes for leaf or flowers, and 10 - 20 minutes for roots. Drink 2 - 4 cups per day. You may use tinctures alone or in combination as noted.

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anticancer and immune effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Reishi mushroom (Ganoderma lucidum) standardized extract, 150 - 300 mg two to three times daily, for anticancer and immune effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Maitake mushroom (Grifola frondosa) standardized extract (D-fraction), 600 mg twice daily, for immune and anticancer effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Olive leaf (Olea europaea) standardized extract, 250 - 500 mg one to three times daily, for anticancer and immune effects.
Turmeric (Curcuma longa) standardized extract, 300 mg three times a day, for pain and inflammation.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for anticancer and immune effects.

Acupuncture

While acupuncture is not used as a treatment for cancer itself, evidence suggests it can be a valuable therapy for cancer-related symptoms (particularly nausea and vomiting that often accompanies chemotherapy treatment). Studies have indicatedthat acupuncture may help reduce pain and shortness of breath. Acupressure (pressing on rather than needling acupuncture points) has also proved useful in controlling breathlessness. Patients can learn this technique and use to treat themselves.

Some acupuncturists prefer to work with a patient only after the completion of conventional medical cancer therapy. Others will provide acupuncture or herbal therapy during active chemotherapy or radiation. Acupuncturists treat cancer patients based on an individualized assessment of the excesses and deficiencies of qi located in various meridians. In many cases of cancer-related symptoms, a qi deficiency is usually detected in the spleen or kidney meridians.

Mind-Body Medicine

Relaxation techniques are beneficial for individuals undergoing surgery. In one study it was observed that patients who received standard care plus relaxation techniques in the form of guided imagery audiotapes before, during, and after surgery experienced significantly better sleep and less pain following the surgery than patients who received only standard care.

Other Considerations

Pregnancy

Colorectal cancer may be detected late in pregnant women because symptoms of the disease, such as rectal bleeding, nausea, and vomiting, resemble the symptoms of pregnancy. Pregnant women should avoid chemotherapy and radiation therapy. Surgery puts the fetus at risk, therefore folic acid and nutritional needs are usually maintained during pregnancy, and treatment is postponed until after the baby is delivered.

Prognosis and Complications

Follow-up care after treatment for colorectal cancer is very important. If the cancer returns or if new cancer develops, it should be treated as soon as possible. If left untreated, colorectal cancer can spread to the liver or lungs, or a tumor may block the colon. In some cases, individuals with colorectal cancer may need to have their entire colon or rectum removed. If the surgeon cannot reconnect healthy portions of the colon or rectum, a temporary or permanent surgical opening (stoma) is made through the wall of the abdomen into the colon to provide a new path for waste material to leave the body. After this procedure, a special bag is worn to collect body waste. Individuals who wear the bag may need counseling on how to care for the stoma as well as how to deal with the emotional difficulties associated with this procedure.

The outlook in cases of colorectal cancer depends on how deeply the tumor has penetrated into the tissue and whether the cancer has spread to lymph nodes in the abdominal region or to other areas of the body. Following are the proportions of individuals who survive at least 5 years based on the stage of their disease when it was first diagnosed:

Stage A -- more than 90%
Stages B1 and B2 -- 85%
Stage C -- 70% to 80%
Stage D -- 5%

HEALTH GUIDE REFERENCE FROM A.D.A.M

Lung cancer is the most common cause of cancer death, responsible for an estimated 160,000 deaths in the United States annually. There are two major types: non-small cell lung cancer and small cell lung cancer, so-named because of how the cells look under a microscope. Non-small cell lung cancer is more common, and it generally grows and spreads more slowly. There are three main types of non-small cell lung cancer, named for the type of cells in which the cancer develops: squamous cell carcinoma, adenocarcinoma, and large cell lung cancer. Small cell lung cancer grows more quickly and is more likely to spread to other organs in the body.

Signs and Symptoms

Lung cancer is accompanied by the following signs and symptoms:

A persistent cough that gets worse over time
Constant chest pain
Coughing up blood
Shortness of breath, wheezing, or hoarseness
Repeated pneumonia or bronchitis
Swelling of the neck and face
Loss of appetite or weight loss
Fatigue

What Causes It?

Multiple exposure to carcinogens (cancer-causing agents) results in damage to DNA in the cells of the body.

Who's Most At Risk?

Tobacco smoke is the biggest carcinogen, responsible for 85% of all lung cancers in the United States. Risk increases with the amount of tobacco used, and the amount of time it has been used. Non-smokers exposed to tobacco smoke are also at risk for developing lung cancer. Other risk factors include the following:

Family history
Environmental and occupational exposure to certain substances, including arsenic, asbestos, ether, chromium, nickel, and radon
Exposure to excessive radiation (wartime or industrial exposure, or radiotherapy to the chest)
Lung diseases
Poor diet (however, diets high in fruits and vegetables can decrease your risk)

What to Expect at Your Provider's Office

If you are experiencing symptoms associated with lung cancer, you should see your health care provider. Your health care provider will evaluate your medical history, smoking history, exposure to environmental and occupational substances, and family history of cancer, and will perform a physical exam.

You may be sent for a chest x-ray and other tests. These include a sputum cytology, the microscopic examination of cells obtained from a deep-cough sample of mucus in the lungs. A biopsy -- the removal of a small sample of tissue for examination under a microscope by a pathologist -- can confirm whether you have cancer.

If you have cancer , your health care provider will want to learn the stage (or extent) of the disease to find out whether the cancer has spread, particularly to the brain or bones, using tests such as computed tomography (CT) scan, magnetic resonance imaging (MRI), radionuclide scan, and bone scan.

Treatment Options

Prevention

The best means of prevention is to never start smoking or using chewing tobacco, or to stop using tobacco products. A healthy diet is an important part of prevention.

Treatment Plan

A treatment plan depends on the cell type, stage of disease, possibility for removing the tumor, and the patient's ability to survive surgery.

Drug Therapies

Various therapies can treat lung cancer.

Chemotherapy can control cancer growth and relieve symptoms.
Photodynamic therapy involves the use of a chemical that is injected into the bloodstream and absorbed by cells all over the body, and which remains in cancer cells for a longer time. A laser light activates the chemical, which then kills the cancer cells. Photodynamic therapy may be used to control bleeding, relieve breathing problems, or to treat very small tumors.

Surgical and Other Procedures

Surgery is the only treatment that offers hope of a cure of non-small cell lung cancer. Removal of a small part of the lung is a segmental or wedge resection, removal of an entire lobe of the lung is a lobectomy, and removal of an entire lung is a pneumonectomy. Radiation therapy is used before surgery to shrink a tumor, or after surgery to destroy remaining cancer cells. Radiation therapy may also be used instead of surgery or to relieve symptoms such as shortness of breath.

Complementary and Alternative Therapies

A comprehensive treatment plan for lung cancer may include a range of complementary and alternative therapies. Ask your team of health care providers about the best ways to incorporate these therapies into your overall treatment plan. Always tell your health care provider of herbs and supplements you are taking.

Nutrition and Supplements

Following these nutritional tips may help reduce symptoms:

Try to eliminate suspected food allergens, such as dairy (milk, cheese, and ice cream), wheat (gluten), soy, corn, preservatives and chemical food additives. Your health care provider may want to test you for food allergies.
Eat foods high in B-vitamins and iron, such as whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables.
Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes) and vegetables (such as squash and bell pepper).
Avoid refined foods such as white breads, pastas, and sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein. You should use quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes as part of a balanced program aimed at gaining muscle mass and preventing wasting that can sometimes be a side effects of cancer therapies.
Use healthy cooking oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in such commercially baked goods as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid caffeine and other stimulants, alcohol, and tobacco.
Exercise lightly, if possible, 5 days a week.

You may address nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-complex vitamins and trace minerals such as magnesium, calcium, zinc and selenium.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tbsp. of oil one to two times daily, to help decrease inflammation and help with immunity. Cold-water fish, such as salmon or halibut, are good sources.
Vitamin C, 500 - 1000 mg one to two times daily, as an antioxidant and for immune support.
Alpha-lipoic acid, 25 - 50 mg twice daily, for antioxidant support.
Resveratrol (from red wine), 50 - 200 mg daily, to help decrease inflammation and for antioxidant effects.
L-theanine, 200 mg one to three times daily, for nervous system and immune support.
Melatonin, 2 - 6 mg at bedtime, for immune support and sleep. Higher doses may be beneficial in lung cancer, so check with your health care provider.

Herbs

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anticancer, and immune effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Reishi mushroom (Ganoderma lucidum) standardized extract, 150 - 300 mg two to three times daily, for anticancer and immune effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Olive leaf (Olea europaea) standardized extract, 250 - 500 mg one to three times daily, for anticancer and immune effects.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for anticancer and immune effects.

Homeopathy

An experienced homeopath can prescribe a regimen for supporting general health during lung cancer that is designed especially for you. Acute remedies may be useful for relief of symptoms associated with complications.

Homeopathy may help reduce symptoms and strengthen overall constitution, reduce the effects of stress during cancer, and may help decrease the side effects of chemotherapy.

Radium bromatum is specific for radiation poisoning, especially followed by arthritic complaints. Acute dose is three to five pellets of 12X to 30C every 1 - 4 hours until symptoms are relieved.

Physical Medicine

Castor oil pack over lungs may decrease side effects of chemotherapy and aid the lungs in detoxification. Saturate a cloth with castor oil and apply directly to the skin, placing a heat source (heating pad or water bottle) on top. Leave in place for 30 minutes or more. For best results, use castor oil packs for three to four consecutive days per week. Packs may be used daily.

Acupuncture

While acupuncture is not used as a treatment for cancer itself, evidence suggests it can be a valuable therapy for cancer-related symptoms (particularly nausea and vomiting that often accompany chemotherapy treatment). Studies have indicated that acupuncture may help reduce pain and shortness of breath. Acupressure (pressing on rather than needling acupuncture points) has also proved useful in controlling breathlessness. Patients can learn this technique to treat themselves.

Prognosis/Possible Complications

The outlook varies by cell type and stage of the disease. In general, the prognosis is better for squamous cell cancers than for adenocarcinomas. Early detection is key to better chances of survival.

Following Up

Periodic follow-up is useful in helping to detect recurrence of the lung cancer or other smoking-related cancers. Frequent follow-up and rehabilitation for loss of lung function from cancer, surgery, or other treatment may be necessary.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Prostate cancer is a cancerous (malignant) tumor that originates in the prostate gland and can eventually spread to other organs, bones, and tissues. The prostate is a cluster of small glands located beneath the bladder that surrounds the urethra, the tube that carries urine from the bladder out through the penis. Its principle function is to manufacture fluid that constitutes a portion of the semen.

Prostate cancer is the third most common cause of death from cancer in men of all ages and is the most common cause of death from cancer in men over 75 years old. Prostate cancer is rarely found in men younger than 40. Men at higher risk include African-America men older than 60, farmers, tire plant workers, painters, and men exposed to cadmium. The lowest number of cases occurs in Japanese men and those who do not eat meat (vegetarians).

Fortunately, prostate cancer tends to be slow-growing compared to many other cancers -- the majority of prostate cancers either do not spread or cause harm for decades.

Signs and Symptoms

Many people with prostate cancer experience no symptoms at all.

Some symptoms that may indicate prostate cancer include:

Difficult and painful urination
Frequent urination and a feeling that one has to urinate even when the bladder is empty
Incomplete emptying of the bladder, which may lead to dribbling of urine
Awakening frequently in the night to urinate
Decreased force of urine stream
Blood in the urine
Hip and back pain

When the cancer has spread to other parts of the body, symptoms can include:

Bone pain
Weakness or paralysis caused by compression of the spinal cord
Weight loss
Anemia
Kidney failure

Causes

The cause of prostate cancer is unknown, although some studies have shown a relationship between high dietary fat intake and increased testosterone levels.. The influence of genes on the development of prostate cancer is suggested by the fact that prostate cancer tends to occur in men who are related to one another (see Risk Factors section). In addition, researchers have identified a gene that is associated with 30% of family-related prostate cancers.

Reports also indicate that farmers as well as men who work in tire, rubber, and sheet metal factories tend to have high rates of prostate cancer or more aggressive forms of the cancer. Some researchers speculate that environmental exposure to cadmium (present in commercial fungicides) and other harmful substances may be responsible for the high rates of prostate cancer in these men.

Nutrition has been implicated in the development of prostate cancer because disease rates among men from countries with low prostate cancer rates (such as Japan) increase when they immigrate to the United States. This rise in incidence is thought to be due to the switch to a typical American diet, which is high in saturated fat. Elevated levels of male sex hormones, such as testosterone, may also play a role in the development of prostate cancer.

Risk Factors

The following factors may increase a man's risk for prostate cancer:

Older age -- prostate cancer is most common among men who are older than 55.
Race -- African-Americans have a greater risk of developing prostate cancer than Caucasians who, in turn, have a greater risk than Native and Latin Americans.
Family history of prostate cancer -- having a brother with prostate cancer makes a man 4.5 times more likely to develop the disease. Having a father with prostate cancer makes a man 2.3 times more likely to develop prostate cancer.
High-fat diet -- foods rich in saturated fat may increase testosterone levels.
Lack of exercise may increase the risk in those who eat a high-fat diet.
Occupation -- people who are regularly exposed to the chemicals dimethyl formamide and acrylonitrate, and the metal cadmium (such as metal workers and farmers), have high rates of prostate cancer.

Diagnosis

Two standard tests are used for early detection of prostate cancer:

Digital rectal exam (DRE) -- in this test, the physician inserts a gloved, lubricated finger into the patient's rectum in order to feel the prostate for bumps or other abnormalities. Many malignant tumors originate in the outer part of the prostate where they may be detected by this exam. Some men find this test embarrassing, but the DRE is quick and relatively painless, and helps detect many prostate cancers. Although some tumors identified using DRE have already spread outside of the prostate gland, studies indicate that regular DREs still save lives.
PSA test -- blood test measuring the level of prostate-specific antigen (PSA), a protein produced in the prostate gland that keeps semen in liquid form. Prostate cancer cells produce elevated quantities of PSA, so measuring PSA levels allows physicians to detect cancer while it is still microscopic. Unfortunately, the test is not accurate enough to definitively rule out or confirm cancer. For example, advancing age and benign conditions such as enlarged prostate can also elevate PSA levels.

If either the DRE or PSA test suggests the possible presence of cancer, the following tests will be performed to make a definite diagnosis:

Transrectal Ultrasound -- a visual image of the prostate is obtained by using ultrasound.
Biopsy of the prostate -- a tissue sample is obtained through the rectum and examined for cancerous cells under the microscope.

If the biopsy confirms the presence of cancer, several tests will be performed to detect any spread of the disease. This information gauges how serious the prostate cancer is at the time of diagnosis. Likely tests include the following:

Imaging tests (CT and MRI) -- computerized tomography (CT) or magnetic resonance imaging (MRI) scans may pinpoint the location of cancer that has spread beyond the prostate.
Bone scans and x-rays -- these techniques look for spread of cancer to the bones.
Lymph node dissection -- this is part of a surgical procedure to determine if the cancer has spread to the lymphatic system.

Preventive Care

Regular screening with the DRE and PSA exams by a doctor may help detect prostate cancer in the early stages, before it has spread. Both the American Cancer Society and the American Urological Association recommend that men between the ages of 50 - 70 should have annual DRE or PSA tests. African-American men or those with a family history of prostate cancer should begin screening at age 40.

Studies also suggest that the following lifestyle modifications may minimize the risk of prostate cancer:

Consuming a low-fat diet, rich in fruits and vegetables
Eating foods rich in selenium (such as brewer's yeast, wheat germ, chicken liver, nuts and seeds, tuna and herring) and vitamin E (such as wheat germ, organ meats, sweet potatoes, leafy vegetables including spinach, nuts and seeds, eggs, soybeans, and lima beans)
Exercising regularly, because exercise temporarily lowers testosterone

Treatment

Treatment for prostate cancer depends on the stage of the disease, the age of the individual, the presence of other medical conditions, and the man's preferences in conjunction with the physician's recommendations.

If prostate cancer is detected early, treatment usually involves either surgical removal of the prostate or radiation therapy. For more advanced cases of prostate cancer, or if cancer spreads beyond the prostate, hormone medications are the preferred treatment.

If the man is older than 70 and has only a slow-growing tumor, the physician may adopt a strategy called "watchful waiting," in which the man returns frequently for check-ups. Treatment occurs only if the man's condition worsens.

Dietary modifications may slow the growth of the cancer in men undergoing watchful waiting, as well as those who have had surgery or are being treated iwth with medication or radiation. For example, eating a low-fat diet, rich in fruits, vegetables, soy, selenium, and fiber has been associated with a decreased risk of prostate cancer.

Saw palmetto, a widely studied herb, appears to significantly reduce symptoms associated with benign prostatic hypertrophy (BPH) and may be used in prostate cancer, but only under the supervision of a doctor.

Acupuncture can relieve pain and the side effects of surgery while meditation and massage may reduce stress and anxiety associated with having prostate cancer.

Medications

Medications are considered the best therapy for people with advanced stages of prostate cancer or when cancer spreads from the prostate to other parts of the body. Drugs may also be prescribed prior to radiation therapy or when surgical procedures fail to lower PSA levels. Most medications for prostate cancer lower levels of male sex hormones (such as testosterone). Lowering testosterone levels can cause tumors to shrink or slow their growth.

Some commonly prescribed medications include:

Luteinizing Hormone-Releasing Hormone (LH-RH) agonists (such as leuprolide, goserelin, and buserelin) -- LH-RH is natural hormone, released by the hypothalamus in the brain, that lowers the production of testosterone, and the medication encourages the release of this natural hormone. Side effects can include hot flashes, weight gain, development of male breast tissue, breast pain, and nausea.
Hormones including antiandrogens (such as flutamide, bicalutamide, and nilutamide) and estrogens (such as diethylstilbestrol) -- these medications reduce testosterone levels, but side effects can include reduced sex drive, fatigue, nausea, impotence, diarrhea, and hot flashes.
Chemotherapeutic medications (such as mitoxantrone and estramustine) -- improve symptoms in advanced cancer but do not increase life expectancy

Surgery and Other Procedures

Removal of the prostate (prostatectomy) -- offers an excellent cure for men with prostate cancer that is completely confined to the prostate, and is performed if life expectancy is at least 10 years and cancer is confined to the prostate. Side effects include incontinence and impotence, but new procedures that spare nerves near the prostate preserve sexual function in 25 - 90 % of men.
Surgical exploration of lymph nodes -- may be performed to evaluate whether prostate cancer has spread to the lymphatic system.
Resection of the prostate (called TURP or transurethral resection of the prostate) -- removal of all or part of the prostate gland to eliminate cancer and to relieve obstruction of urine.
Removal of the testes (orchiectomy) -- lowers testosterone levels, but side effects can include impotence and hot flashes.

In addition to these surgical procedures, radiation therapy may be effective for cancer confined to the prostate, particularly for older men. Radiation can be administered through an external source, or irradiated seeds can be placed internally near the prostate. Using irradiated seeds actually lowers the risk of damage to organs surrounding the prostate from radiation because administration can be more precise in both amount and location. Side effects can include proctitis (inflammation of the lining of the rectum), urinary tract infections, and impotence.

Nutrition and Dietary Supplements

A comprehensive treatment plan for support of the health of men living with prostate cancer may include a range of complementary and alternative therapies. Preliminary studies suggest that nutritional supplements may reduce the symptoms of some prostate cancer. Ask your team of health care providers about the best ways to incorporate these therapies into your overall treatment plan. Always tell your health care provider about the herbs and supplements you are using or considering using.

Following these nutritional tips may help reduce symptoms:

Eat foods high in B-vitamins and calcium, such as almonds, beans, whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables. A study found that men who consumed 28 or more servings of vegetables per week were 35% less likely to develop prostate cancer than those who had less than 14 servings per week.
Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes) and vegetables (such as squash and bell peppers).
Avoid refined foods, such as white breads, pastas, and especially sugar.
Quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes, may be used as part of balanced program aimed at gaining muscle and preventing weight loss that can sometimes be a side effect of cancer therapy. Try to eat fewer red meats and more lean meats such as chicken and fish, tofu (soy, if no allergy), or beans for protein.
Eat cruciferous vegetables (such as broccoli, cabbage, and cauliflower) -- they contain special cancer fighting chemicals.
Use healthy oils in foods, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in commercially baked goods such as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid coffee and other stimulants, alcohol, and tobacco.
Drink 6 - 8 glasses of filtered water daily.
Exercise at least 30 minutes daily, 5 days a week.

You may address nutritional deficiencies with the following supplements:

A daily multivitamin, containing the antioxidant vitamins A, C, E, the B-complex vitamins, and trace minerals such as magnesium, calcium, and selenium.
Calcium D-glucarate, 200 - 400 mg daily, for support of immunity and anticancer effects.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 - 3 tablespoonfuls oil, one to three times daily, to help decrease inflammation and help with immunity. Cold-water fish, such as salmon or halibut, are good sources but not substitutes for supplementation.
Whey protein, 10 - 20 grams daily mixed in favorite beverage, when needed as a protein supplement for support of immunity and weight gain; or creatine, 5 - 7 grams daily, when needed for muscle weakness and wasting. Talk with your health care provider.
N-acetyl cysteine, 200 mg one to three times daily, for antioxidant effects.
Probiotic supplement (containing Lactobacillus acidophilus among other strains), 5 - 10 billion CFUs (colony forming units) a day, when needed for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
Astaxanthin, 2 - 6 mg daily, for immune and antioxidant support.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant and immune activity.
Vitamin C, 500 - 1,000 mg one to three times daily, as an antioxidant and for immune support. Some doctors will use higher doses in alternative cancer therapies. Check with your health care provider.
Lycopene, 5 mg one to three times daily, for antioxidant and anticancer activity. In a large study, lycopene levels were significantly lower in those with prostate cancer compared to those without.
L-glutamine, 500 - 1,000 mg three times daily, for support of gastrointestinal health and immunity.
Melatonin, 2 - 5 mg one hour before bedtime, for sleep and immune protection. Ask your health care provider about potential drug interactions with the use of melatonin.

Herbs

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anti-inflammatory and immune effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Saw palmetto (Serenoa repens) standardized extract, 160 mg two times daily, for hormonal support. There has been some concern that saw palmetto could mask prostate cancer by lowering prostate-specific antigen (PSA) levels. However, a randomized study of more than 1,000 patients did not demonstrate this effect on PSA levels. Talk to your health care provider about using saw palmetto for your condition.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for anticancer and immune effects. Ask your health care provider for more about this supplement.
Bitter Melon (Momordica charantia) standardized extract, 200 mg two to three times daily, for anticancer and immune support.
Maitake mushroom (Grifola frondosa) standardized extract (D-fraction), 600 mg twice daily, for immune and antiviral effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Garlic (Allium sativum), standardized extract, 400 mg two to three times daily, for antibacterial or antifungal and immune activity.

Acupuncture

Acupuncture may provide relief from side effects of orchiectomy (removal of the testes). Studies also support the use of acupuncture for the pain that often occurs when cancer has spread beyond the prostate (particularly to the bones). A National Institutes of Health statement released in 1997 also supports the use of acupuncture to alleviate nausea associated with chemotherapy.

Evidence suggests acupuncture can be a valuable therapy for cancer-related symptoms (particularly nausea and vomiting that often accompanies chemotherapy treatment). Studies have also indicated that acupuncture may help reduce pain and shortness of breath. Acupressure (pressing on rather than needling acupuncture points) has also proved useful in controlling breathlessness and is a technique that patients can learn and then use to treat themselves.

Massage and Physical Therapy

Studies suggest that massage reduces stress and boosts immune function, so it may help relieve anxiety for men undergoing treatment for prostate cancer.

Pelvic floor exercises -- the repetitive use of muscles that start and stop the flow of urine -- may help decrease incontinence caused by prostatectomy (removal of the prostate). This therapeutic approach is often combined with biofeedback.

Mind-Body Medicine

Meditation

Meditation may benefit men with prostate cancer by helping them to reduce stress, ease anxiety, and regain a sense of self-control.

Biofeedback and Pelvic Muscle Training (PMT)

Several studies have found that learning to start and stop the flow of urine by repeatedly using the muscles of the pelvis (PMT) in combination with biofeedback can reduce the duration of incontinence after prostate cancer surgery. Other studies suggest however, that PMT alone, with or without biofeedback, is responsible for the beneficial effects. Either way, both PMT and biofeedback are safe, noninvasive therapies that may benefit men who suffer from incontinence following either surgical removal of the prostate or other treatments for prostate cancer.

Other Considerations

Prognosis and Complications

Most complications from prostate cancer result from specific treatments. These include:

Prostatectomy -- can cause incontinence and impotence
Radiation therapy -- can cause proctitis (inflammation of the lining of the rectum), bladder infections, and impotence
Hormone medications -- can cause loss of libido, impotence, hot flashes, excessive development of male breasts, and tenderness in male breast tissue
Removal of testes -- can cause impotence and hot flashes

The outlook for a man with prostate cancer depends on his age, the stage of tumor growth, whether he has any underlying medical illnesses, and his PSA levels. The prognosis for men with cancer that has not spread beyond the prostate is quite good. Most of these cancers are curable with appropriate treatment, and after 15 years the same number of these men will be alive as those who never had prostate cancer. If the cancer spreads beyond the prostate and does not respond to hormone medications, however, there is little hope for a cure. Still, prostate tumors are slow-growing, and even men with advanced prostate cancer can survive for 5 years or more.

HEALTH GUIDE REFERENCE FROM A.D.A.M

More than 17,000 people in the United States are diagnosed each year with a brain tumor. Some tumors are benign (noncancerous), and they can usually be removed and are not likely to recur. Others are malignant (cancerous). They interfere with vital functions and are life-threatening. Cancerous brain tumors usually grow rapidly, crowding and invading tissue.

Primary brain tumors are cancers that arise in the brain and affect the central nervous system (CNS). Secondary brain tumors, which are 10 times more common, are cancers that originated elsewhere in the body and have metastasized (spread) to the brain.

Signs and Symptoms

A brain tumor can be accompanied by the following signs and symptoms.

Headaches that often are worse in the morning
Seizures (convulsions)
Nausea or vomiting
Weakness or loss of feeling in the arms or legs
Stumbling or lack of coordination when walking
Abnormal eye movements or changes in vision
Drowsiness
Changes in personality or memory
Changes in speech

Who's Most At Risk?

People with the following conditions or characteristics may be at risk for developing a brain tumor.

Radiation exposure
Increased age
Exposure to pesticides, herbicides, fertilizer
Certain occupations, such as lead, petroleum, plastic, rubber, and textile workers, as well as aircraft and vehicle operators
Exposure to electromagnetic fields
Certain viruses, especially Epstein-Barr virus
People who have had transplants and individuals with AIDS

What to Expect at Your Provider's Office

If you symptoms of a brain tumor, you should see your health care provider immediately. Your provider will ask about your personal and family medical history and perform a complete physical and neurologic exam. This includes checks for alertness, muscle strength, coordination, reflexes, and response to pain, and an eye exam to look for swelling caused by a tumor pressing on the nerve that connects the eye and the brain. The provider may send you for a computed tomography (CT) scan or magnetic resonance imaging (MRI). Additional tests may include skull x-ray, brain scan, angiogram or arteriogram, and a myelogram (x-ray of the spine, using dye). If cancer is present, others who may become involved in your care include a neurosurgeon, medical oncologist, radiation oncologist, nurse, dietitian, social worker, physical therapist, occupational therapist, and speech therapist.

Treatment Options

Treatment Plan

Treatment for a brain tumor depends on the type, location, and size of the tumor, as well as the person's age and general health. Treatment generally involves surgery, radiation therapy, or chemotherapy.

Drug Therapies

Your provider may prescribe the following therapies.

Steroids, to relieve swelling
Anticonvulsants, to prevent or control seizures
Radiation therapy, to destroy tumor tissue that cannot be removed with surgery or to kill cancer cells that may remain after surgery, or when surgery is not possible
Chemotherapy, to kill cancer cells

Surgical and Other Procedures

Surgery is the most common treatment. To remove a brain tumor, a neurosurgeon performs a craniotomy, which involves making an opening in the skull. If the tumor cannot be at least partially removed, the surgeon may do only a biopsy, in which a small piece of the tumor is removed so that a pathologist can examine it under a microscope to determine the type of cancer cells. This necessary information helps determine other forms of treatment.

Another procedure sometimes used is insertion of a shunt to drain cerebrospinal fluid. A shunt is a long, thin tube placed in the brain and then threaded under the skin to another part of the body, usually the abdomen. It works like a drainpipe, allowing excess fluid to be carried away from the brain and absorbed in the abdomen.

Complementary and Alternative Therapies

A comprehensive treatment plan for brain cancer may include a range of complementary and alternative therapies. Nutrients and herbs may protect against side effects from conventional therapies as well as enhance chemotherapy and support anticancer activities. Mind-body therapies such as meditation, relaxation techniques, yoga, and qi gong may reduce the effects of stress and enhance your quality of life and your response to treatment. Ask your team of health care providers about the best ways to incorporate these therapies into your overall treatment plan, and make sure you always tell your health care provider which herbs and supplements you are taking.

Nutrition and Supplements

Following these nutritional tips may help reduce symptoms:

Try to eliminate suspected food allergens, such as dairy (milk, cheese, and ice cream), wheat (gluten), soy, corn, preservatives and chemical food additives. Your health care provider may want to test you for food allergies.
Eat foods high in B-vitamins, calcium, and iron, such as almonds, beans, whole grains (if no allergy), dark leafy greens (such as spinach and kale), and sea vegetables.
Eat cruciferous vegetables (such as broccoli, cabbage, and cauliflower).
Eat antioxidant foods, including fruits (such as blueberries, cherries, and tomatoes) and vegetables (such as squash and bell pepper).
Avoid refined foods such as white breads, pastas, and sugar.
Eat fewer red meats and more lean meats, cold-water fish, tofu (soy, if no allergy) or beans for protein. Quality protein sources, such as organic meat and eggs, whey, and vegetable protein shakes, should be used as part of balanced program aimed at gaining muscle mass and preventing wasting that can sometimes be a side effects of cancer therapies.
Use healthy cooking oils, such as olive oil or vegetable oil.
Reduce or eliminate trans-fatty acids, found in such commercially baked goods as cookies, crackers, cakes, French fries, onion rings, donuts, processed foods, and margarine.
Avoid caffeine and other stimulants, alcohol, and tobacco.
Exercise, if possible, 5 days a week.

You may address nutritional deficiencies with the following supplements:

A multivitamin daily, containing the antioxidant vitamins A, C, E, the B-complex vitamins, and trace minerals such as magnesium, calcium, zinc and selenium.
Probiotic supplement (containing Lactobacillus acidophilus), 5 - 10 billion CFUs (colony forming units) a day, for maintenance of gastrointestinal and immune health. You should refrigerate your probiotic supplements for best results.
Omega-3 fatty acids, such as fish oil, 1 - 2 capsules or 1 tbsp. of oil one to two times daily, to help decrease inflammation and help with immunity. Cold-water fish, such as salmon or halibut, are good sources.
Vitamin C, 500 - 1,000 mg daily, as an antioxidant and for immune support.
Lycopene, 5 mg one to three times daily, for antioxidant and anticancer activity.
Alpha-lipoic acid, 25 - 50 mg twice daily, for antioxidant support.
Resveratrol (from red wine), 50 - 200 mg daily, to help decrease inflammation and for antioxidant effects.
Coenzyme Q10, 100 - 200 mg at bedtime, for antioxidant and immune activity.
L-theanine, 200 mg one to three times daily, for nervous system and immune support.
Melatonin, 2 - 6 mg at bedtime, for immune support and sleep. Higher doses may be needed in cancer. Consult your health care provider.

Herbs

Green tea (Camellia sinensis) standardized extract, 250 - 500 mg daily, for antioxidant, anticancer and immune effects. Use caffeine-free products. You may also prepare teas from the leaf of this herb.
Reishi mushroom (Ganoderma lucidum) standardized extract, 150 - 300 mg two to three times daily, for anticancer and immune effects. You may also take a tincture of this mushroom extract, 30 - 60 drops two to three times a day.
Cat's claw (Uncaria tomentosa) standardized extract, 20 mg three times a day, for anticancer, immune, and antibacterial or antifungal activity.
Milk thistle (Silybum marianum) seed standardized extract, 80 - 160 mg two to three times daily, for detoxification support.
Fermented wheat germ extract, 1 packet dissolved in favorite beverage once daily, for anticancer and immune effects.

Combine essential oils of bergamot (Citrus bergamia), chamomile (Matricaria recutita), and lavender (Lavendula angustifolia) in aromatherapy applications. Place several drops in a warm bath, or four to six drops in 1 tbsp. of vegetable oil for massage.

Homeopathy

An experienced homeopath can prescribe a regimen for supporting general health during brain cancer that is designed especially for you. Acute remedies may help relieve symptoms associated with complications.

Homeopathy may help reduce symptoms and strengthen overall constitution, reduce the effects of stress during cancer, and may decrease the side effects of chemotherapy.

Radium bromatum is specific for radiation poisoning, especially followed by arthritic complaints. Acute dose is three to five pellets of 12X to 30C every 1 - 4 hours until symptoms are relieved.

Acupuncture

While acupuncture is not used as a treatment for cancer itself, evidence suggests it can be a valuable therapy for cancer-related symptoms (particularly nausea and vomiting that often accompanies chemotherapy treatment). There have also been studies indicating that acupuncture may help reduce pain and shortness of breath. Acupressure (pressing on rather than needling acupuncture points) has also proved useful in controlling breathlessness. Patients can learn this technique to treat themselves.

Prognosis/Possible Complications

The outlook varies greatly depending on the type of tumor and other factors. Some types of brain cancer have a 5-year survival rate above 80 percent. Brain cancer has significant emotional and psychological effects. Patients who receive radiation therapy to large areas of the brain or certain anticancer drugs may have a higher risk of developing leukemia or a second tumor at a later time. Radiation that affects the eyes may lead to the later development of cataracts.

Following Up

Regular follow-up is very important after treatment, to make sure the tumor has not returned. Checkups usually include physical and neurologic exams and occasional CT scans or MRIs.

HEALTH GUIDE REFERENCE FROM A.D.A.M

Skin cancer is generally a result of too much exposure to the sun. While skin cancer is the most common form of cancer, many types are both preventable and treatable. Skin cancer is classified into five different types:

Basal cell carcinoma (BCC) is the most common form and accounts for 90% of all skin cancers. It originates in the basal cells, at the bottom of the epidermis (outer skin layer), and is caused by long-term exposure to sunlight.
Squamous cell carcinoma (SCC) is the second most common type. It originates in the epidermis, eventually penetrating the underlying tissue if not treated. In a small percentage of cases, this cancer spreads (metastasizes) to other parts of the body.
Malignant melanoma (MM) is a form of skin cancer that currently is affecting an more and more people. Each year, more than 53,000 cases are diagnosed in the U.S. MM is a very serious type of skin cancer, but the cure rate is quite good if it is diagnosed and removed early. Melanoma originates in moles or other growths on normal skin.
Paget's disease (PD) is a rare type of skin cancer. It generally appears on the nipple, and is associated with an underlying breast cancer. It may also appear in the groin or near the anus, possibly originating in the sweat glands.
Kaposi's sarcoma (KS) is caused by a virus in the herpes family. An aggressive AIDS-related form affects about one third of AIDS patients. A more slow growing form occurs in elderly men of Italian or Jewish ancestry.

Signs and Symptoms

Skin cancer is accompanied by the following signs and symptoms:

A new skin lesion or open sores that bleed, ooze, or crust, and fail to heal in an expected time frame
Enlargement of an existing skin lesion
Change in color, size, shape or texture of a mole
A new mole
Reddish patch or irritated area, frequently occurring on the chest, shoulders, arms, or legs
Shiny bump that is pearly or translucent
Poorly defined borders of a skin lesion

What Causes It?

Exposure to ultraviolet (UV) radiation from the sun is the primary cause of skin cancer. A virus causes Kaposi's sarcoma, while Paget's disease is related to underlying breast cancer.

Who's Most At Risk?

People at risk for developing skin cancer may have the following conditions or characteristics:

Light skin color
Spend a lot of time outdoors in work or leisure activities
History of severe sunburn
Family history of skin cancer
Large dark-colored birthmark known as congenital melanocytic nevus
Certain non-cancerous skin conditions, such as actinic keratosis, which can predispose a person to skin cancer
HIV (human immunodeficiency virus) -- a risk for Kaposi's sarcoma specifically

What to Expect at Your Provider's Office

Your health care provider will examine your skin for new, changed, or unusual moles. This may involve the use of a dermatoscope, which is used for close examination of skin growths. Your health care provider will take a biopsy of any growths that appear cancerous. This involves removing a small piece of skin for microscopic examination. A biopsy can confirm whether or not you have skin cancer.

Treatment Options

Prevention

Skin cancer is a preventable disease. If you are at high risk, avoid sun exposure. When you have to be in the sun, protect yourself by covering up, wearing a hat, and applying sunscreen with an SPF of at least 30. You should also have regular skin cancer screenings with your primary health care provider or a skin specialist (dermatologist).

Treatment Plan

The primary goals of treatment are to remove the cancerous growth and stop the spread of the disease.

Drug Therapies

Melanoma that is deep or has spread and AIDS-related Kaposi's sarcoma may be treated with chemotherapy.

Surgical and Other Procedures

Most skin cancer can be surgically removed.
When surgery is not possible, cryotherapy (freezing), topical chemotherapy, or radiation may be used. If the cancer is on or close to the skin's surface, photodynamic therapy (laser) may be used.
Paget's disease of the nipple usually requires mastectomy (removal of breast tissue).

Complementary and Alternative Therapies

Alternative treatments are focused on preventing rather than treating skin cancer. In addition, some CAM treatments may reduce the side effects of conventional treatments. Finally, while many CAM treatments have not yet undergone rigorous scientific research, evidence suggests that some treatments may be useful when applied along with conventional treatments for skin conditions, including skin cancer. You should never rely on alternative therapies alone for treating skin cancer.

Nutrition

Eating certain foods or following therapeutic diets may help prevent skin cancer. It is hard to test the role of nutrients in protecting against various forms of skin cancer, but several studies have investigated the role of antioxidants (including vitamin C, vitamin E, beta-carotene, zinc, and vitamin A), folic acid, fats and proteins, and a variety of whole foods. While results are not absolutely clear, there may be some protective effect from antioxidants. There may also be a protective effect from foods such as fish, beans, carrots, chard, pumpkin, cabbage, broccoli, and vegetables containing beta-carotene and vitamin C. Studies on animals suggest that lignans, substances found in foods such as soy and flaxseed, may also help fight cancer in general, including the spread of melanoma from one part of the body to another.

Other substances found in plants may help protect the skin from sun-related damage. These include

Apigenin, a flavanoid in vegetables and fruits, including broccoli, celery, onions, tomatoes, apples, cherries and grapes, and in tea and wine
Curcumin, in the spice turmeric
Resveratrol, in grape skins, red wine, and peanuts
Quercetin, a flavanoid in apples and onions

Selenium has been touted as an antioxidant that might help prevent skin cancer. One study, however, suggests that selenium might actually increase the risk of developing squamous cell cancer.

Therapeutic diets may also help with skin cancer. An example the Gerson diet, which is customized for each patient. This diet may enhance treatment of melanoma. It strives for a low-fat, low-salt diet, hourly feedings of highly concentrated raw fruit and vegetable juice nutrients, and strategies to speed up metabolism (the breakdown and use of food), such as exercise, taking supplements, and restricting calories. Castor oil, administered every other day for several weeks, and coffee enemas given as frequently as every 4 hours over a 24-hour period, are thought to alleviate pain and improve nutritional status.

Herbs

Naturopathic doctors and botanists recommend a number of herbs and herbal combinations to prevent and treat cancer in general. To identify appropriate herbs to use in your treatment for skin cancer, see a trained herbalist, who will consider your condition and may prescribe herbs to support your care.

Green tea (Camellia sinensis) contains polyphenols, compounds that are potent antioxidants. Antioxidants eliminate free radicals, harmful by-products of cells' metabolism that are thought to play a role in cancer. The main polyphenol in green tea is epigallocatechin gallate (EGCG). Scientific studies suggest that EGCG and green tea polyphenols may prevent the onset and growth of skin tumors.

Other herbs with antioxidant and skin-protecting effects include bilberry (Vaccinium myrtillus), ginkgo (Ginkgo biloba), milk thistle (Silybum marianum), ginger (Zingiber officinale), and hawthorn (Crataegus laevigata ).

For Kaposi's sarcoma, some naturopaths recommend a paste made from lemon balm (Melissa officinalis) cream, several drops of Hoxsey-like formula (a mixture of herbs and potassium iodide thought to be effective against cancer), and powdered turmeric applied to lesions twice a day.

An animal study conducted in China investigated the effects of Cordyceps sinensis on natural killer cells. These are white blood cells that attack cancer and other harmful substances in the body. The study found that Cordyceps sinensis was effective against malignant melanoma by promoting natural killer activity and inhibiting tumor formation.

You should remember that certain herbs and nutrients can alter the way medications, including chemotherapy, act in your body. Make sure you keep your conventional and alternative health care providers informed about all the supplements, therapies, and medications you are using.

Homeopathy

Homeopathy is widely used among patients with melanoma, and warrants scientific investigation. An experienced homeopath considers your individual case and recommends treatments that address both your underlying condition andany symptoms you may be having.

Acupuncture

Acupressure (pressing on rather than needling acupuncture points) has also proved useful in controlling breathlessness. Acupressure is technique that patients can learn and use to treat themselves.

Some acupuncturists prefer to work with a patient only after they have completed conventional medical cancer therapy. Others will provide acupuncture or herbal therapy during active chemotherapy or radiation. Acupuncturists treat cancer patients based on an individualized assessment of the excesses and deficiencies of qi located in various meridians. In many cases of cancer-related symptoms, a qi deficiency is usually detected in the spleen or kidney meridians.

Massage

Massage is generally not recommended for those who have been diagnosed with skin cancer.

Prognosis/Possible Complications

Prognosis varies depending on the type of skin cancer:

Basal cell carcinoma: generally excellent.
Squamous cell carcinoma: excellent for small lesions removed early and completely.
Malignant melanoma: 5-year survival is almost 100 percent for very superficial lesions removed early. However, thick lesions and melanoma that has spread to other organs have poor prognosis.
Paget's disease: depends on the extent and cell type of the underlying breast cancer.
Kaposi's sarcoma: good for superficial lesions of the slow-growing form in the elderly of Italian or Jewish ancestry. The course of AIDS-related Kaposi's sarcoma depends on the status of the person's immune system.

Following Up

See your provider regularly for screenings to check for a recurrence of skin cancer.

Foods to Stop Avoiding: Mushrooms

FitSugar — Fri, 21 Dec 2007 15:30:00 -0800

Just like anything else foods can get a bad reputation. The thing about reputations is that they can be repaired and scientist are working round the clock to make sure we're not skipping out on foods just because we've heard it through the grapevine that they're bad. Mushrooms, avocados, peanuts, eggs, and coffee top the list of foods with the worst reputations to stop avoiding.

Here are highlights on why you should stop avoiding mushrooms:

Mushrooms
Misconception: Mushrooms are a low-calorie food with little nutritional benefit.
Why they're good for you: They may be 90 percent water and have only 18 calories per cup, but mushrooms are getting serious scientific attention. Laboratory reports and animal studies show that compounds in mushrooms may do everything from bolster immune function to suppress breast and prostate cancers and decrease tumor size. And now, Penn State researchers found that mushrooms, from the humble button to the giant portobello, harbor large amounts of an antioxidant called L-ergothioneine. The scientific buzz is that fungi, for the moment, are the only foods that contain this compound.

Diet Tip: Eat Like the French

Our relationship with our Gallic allies waxes and wanes (remember the Freedom Fries episode), but we Americans could learn a thing or two from the French and their relationship to food.

The adult obesity rate in France is only 11% compared to the U.S. rate of 32%. Well folks at Penn State University and Cornell University decided to turn this statistic into a learning opportunity. Eating slower and savoring your food is a healthier way to eat since it makes less food seem like more and gives the body time to achieve satiation. It also reinforces the well know fact that smaller portions are better, because if there is less on the plate there is less for you to eat.

To read more on the study check out this article on MSNBC.com. Makes me want to head to the City of Lights right now.
