I have always heard that sleeping with a bra on can cause breast cancer, is this true?

No: It is not true that sleeping with a bra on causes breast cancer. It's good for your breasts to have good circulation, like all parts of your body, so wear a bra that fits well and does not bind you anywhere.

No: There has been no scientific evidence that sleeping with a bra on causes cancer of any kind, including breast cancer.

Absolutely not: Whether you wear a bra all the time, or none of the time, or anything in between - has nothing tyo do with developing breast cancer.

Not true: Sleeping with a bra on will not cause breast cancer.
