According to a new study, bras do not cause breast cancer. The new research published in the journal Cancer Epidemiology, Biomakers, & Prevention Sept. 5. The study was conducted by Lu Chen who does research at Fred Hutchinson Cancer Research Center in Seattle to determine if bras increased the chance of tumors. The study consisted of more than 1,000 women who were diagnosed with breast cancer between 2000 and 2004. They were compared to 469 women who did not develop breast cancer. All the women were past menopause and ranged in age from 55 to 74. They took into consideration the woman’s bra size, if they wore underwire bras, how long did they wear their bra, family history of breast cancer, their weight and height as well as their race, income, and whether they used hormone replacement therapy.
Some reports claimed that bras can hamper lymph circulation and drainage which interferes with waste removal thus causing breast cancer. Over the years reports of underwire bras causing cancer would surface as well. This is not the case according to this study. “Our study found no evidence that wearing a bra increases a woman’s risk for breast cancer,” Chen said. “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.”
