Do bras cause breast cancer?
No it is nonsense. I don’t know who wrote that book or who published it, but they have been extremely irresponsible. There are a number of urban myths concerning breast cancer and bras – .you can’t get breast cancer by wearing a badly-fitting or tight bra, or an underwired bra; nor can you get breast cancer from sleeping in a bra, not sleeping in a bra, not wearing a bra or wearing a bra for too long – all questions I have seen on this board. Breast cancer, like all other cancers, happens when normal cells change so that they grow in an uncontrolled way. This uncontrolled growth causes a tumour to form. Underwear has no effect on it.
