Wearing a bra "does not cause cancer"
For years, there have been rumors about whether bras increase a woman's risk for developing breast cancer because of the underwire or the restrictiveness of the garment. But a new study published in Cancer Epidemiology, Biomarkers & Prevention concludes that bras do not increase risk of breast cancer in postmenopausal women.
Researchers from the Public Health Sciences Division at Fred Hutchinson Cancer Research Center conducted interviews with 454 women with the two most common types of breast cancer: invasive ductal carcinoma and invasive lobular carcinoma. The women were between the ages of 55 and 74, with 469 women in the control group.
Participants were asked about their bra wearing habits and the women’s family and reproductive history was also taken into account. Wearing a bra in no way affected the risk for developing either of the two types of breast cancers, according to the researchers. This takes into account wearing bras with underwire, how long a bra is worn every day and at what age women began wearing bras.
