Wearing a bra 'doesn't raise breast cancer risk

Unread post by Kunle Emmanuel » Fri Nov 28, 2014 12:50 pm

“Scientists believe they have answered the decades long debate on whether wearing a bra can increase your risk of cancer,” reports The Daily Telegraph.

There is an “urban myth” that wearing a bra disrupts the workings of the lymphatic system (an essential part of the immune system), which could lead to a build-up of toxins inside breast tissue, increasing the risk of cancer. New research suggests that this fear may be unfounded.

The study compared the bra-wearing habits of 1,044 postmenopausal women with two common types of breast cancer with those of 469 women who did not have breast cancer. It found no significant difference between the groups in bra wearing habits such as when a woman started wearing a bra, whether she wore an underwired bra, and how many hours a day she wore a bra.

The study had some limitations, such as relatively limited matching of characteristics of women with and without cancer. Also, as most women wear a bra, they could not compare women who never wore a bra versus those who wore a bra.

Despite the limitations, as the authors of the study say, the findings provide some reassurance that your bra-wearing habits do not seem to increase risk of postmenopausal breast cancer.

While not all cases of breast cancer are thought to be preventable, maintaining a healthy weight, moderating your consumption of alcohol and taking regular exercise should help lower your risk.

Where did the story come from?

The study was carried out by researchers from Fred Hutchinson Cancer Research Center in the US.

It was funded by the US National Cancer Institute.

The study was published in the peer-reviewed medical journal Cancer Epidemiology Biomarkers & Prevention.

The Daily Telegraph and the Mail Online covered this research in a balanced and accurate way.

However, suggestions that women who wore bras were compared with “their braless counterparts”, are incorrect. Only one woman in the study never wore a bra and she was not included in the analyses. The study was essentially comparing women who all wore bras, but starting at different ages, for different lengths of time during the day, or of different types (underwired or not).
