If you’re a bra-wearing woman, maybe you know this feeling: You exhale with relief as you unhook your band at the end of a long day. Looking over your shoulder into the mirror, you see the slight indentation the elastic has left on your torso, and think: “Constriction like this just can’t be good.”
That intuition resonates with popular theorizing that bras can lead to breast cancer by blocking the healthy drainage of waste products from the breast area. Hence the higher breast cancer rates in developed countries.
But give me good hard data over feelings and pop theories every time. A big new study, funded by the National Cancer Institute, finds no link at all between bras and breast cancer.
The study, published in the journal “Cancer Epidemiology, Biomarkers & Prevention,” found that whether women wear bras just a few hours a day or more than 16, whether they wear underwires or wireless, whether they have big cups or small cups, brassieres are guiltless: They just do not seem to be linked to the two most common forms of breast cancer.
The research involved hundreds of postmenopausal women: 454 with invasive ductal carcinoma, 590 with invasive lobular carcinoma, and 469 without breast cancer, who served as controls. Each woman answered questions about everything from her pregnancy history to the age at which she started wearing a bra, whether it had an underwire, cup size, band size and how many hours a day she wore it.
Bottom line: It looks like your bra won’t kill you unless someone strangles you with it. Which contradicts a 1995 book that added gallons of fuel to the theory that bras are harmful: “Dressed To Kill: The Link Between Breast Cancer and Bras.”
The new paper’s senior author, Dr. Christopher Li, head of the Translational Research Program at the Fred Hutchinson Cancer Research Center, says “Dressed To Kill” provided some of the impetus for the study. Our conversation, lightly edited:
Why did you think this study was worth doing?
The whole theory about bra-wearing and breast cancer came to my attention years ago, when there was this book published called “Dressed to Kill.” The whole premise of the book was that bra-wearing is the primary culprit for breast cancer in the world. Being a breast cancer researcher, I had never heard of this theory, and people, friends of mine who had seen it, were saying, ‘What’s going on with this?’ Continue reading
