Do Bras Cause Breast Cancer?

So recently I heard an astonishing statement from someone in my yoga class. "Wearing a bra causes breast cancer. And under-wires are the worst."


What? This can't be true. Every woman I know wears a bra. And what about men who get breast cancer? I'm sure they don't wear bras. As soon as I got home, I searched for some facts to back this up.

I did find a lot of info "claiming" the same statement, but none of these sites could back it up with science.

I was happy to find this tidbit from the Canadian Cancer Society that said, "At this time, there is no reliable, scientific evidence that shows a link between wearing a bra and developing breast cancer."

CancerHelp UK agreed and said:

No, there is no scientific evidence to prove this. There are a number of rumors that have suggested that bras cause breast cancer by obstructing the lymphatic system. The emphasis has generally been on under-wired bras. These sources claim that bras squash the fine tubes of the lymphatic system. The idea is that this stops the normal drainage of the breast tissues, causing toxins to gather in the breast and resulting in cancer. You would need to wear a bra that was painfully and unbearably tight to have any effect on your lymphatic system.

Oh good. I didn't really like the idea of blowing free in the breeze. So go ahead and support 'em if you got 'em.
