Apr 19, 2007 · Underwire Bras Cause Cancer. Is your bra killing you? By S.M. Kramer on April 19, 2007; Thus, the notion of a correlation between wearing a bra and breast cancer does not appear to hold up.

Evaluating more than 1,000 women with breast cancer and almost 500 who did not have breast cancer, the researchers found no evidence of a connection between the number of hours spent wearing a bra or wearing an underwire bra and increased breast cancer risk. [5].

Can wearing an underwire bra cause breast cancer? The claim that bra-wearing can put women at serious risk for breast cancer has been around for almost 20 years. Does this idea hold any truth? Dr. Laura Hutchins, a UAMS medical oncologist who specializes in breast cancer, says that there is not enough evidence to support this idea.

In media stories and on Internet postings some factors have been widely rumored to increase breast cancer risk. For example, right now, there is no evidence to back the claims that antiperspirants, underwire bras, and wearing a bra at night are causes of breast cancer.

In examining 1,500 women with and without a history of breast cancer, the researchers found that there was zero connection between breast cancer and bra wear, regardless of a woman’s age, how long and at what time of day a bra is worn, at what age bra usage begins, bra style, or even breast/cup size (7).
