No link between bras and breast cancer

CANCER DIGEST – Sept. 5, 2014 – Wearing a bra may not increase your risk of breast cancer, a new population-based study has found.

Since Sydney Ross Singer and Soma Grismaijer published their book, “Dressed to Kill” in 1995, claiming that bra-wearing may be a major cause of breast cancer there have been persistent concerns about about bras and breast cancer. The study they based their claim on has never been published in a peer-reviewed medical journal.

The new study led by LuChen, a researcher in the Public Health Sciences Division at Fred Hutchinson Cancer Research Center interviewed 1085 women with two of the most common forms of breast cancer and 469 women without breast cancer. All were post menopausal between the ages of 55 and 74. The structured interviews assessed lifetime patterns of bra wearing including age when they started wearing a bra, type of bras they wore and amount of time per week they wore them. The study was published in the September Cancer Epidemiology, Biomarkers & Prevention.

"Our study found no evidence that wearing a bra increases a woman's risk for breast cancer. The risk was similar no matter how many hours per day women wore a bra, whether they wore a bra with an underwire, or at what age they first began wearing a bra," said Chen.


  1. Actually, their study supported the bra-cancer link. All the women in their cancer group had worn bras. And since they did not include bra-free women in the study, there was no control group for studying bra impacts. This was just a PR job trying to stem the tide of growing awareness about the bra-cancer link. BTW, Fred Hutchinson Cancer Research Center gets funding from a 5k "Bra Dash", using bras to raise funds.

    1. Mr. Singer, thank you for your comment. I agree, the study design may not have been optimal to answer the question, but the study was funded by the National Cancer Institute and not the Bra Dash.

  2. I think this is an informative post and it is very useful and knowledgeable. therefore, I would like to thank you for the efforts you have made in writing this article. breast augmentation Seattle
