Over the years, there has been speculation that wearing a bra could cause breast cancer by housing toxins in your body. However, a new study suggests that there is no correlation between the two.

The Cancer Epidemgiology Biomarkers and Prevention journal’s evaluated the relationship between wearing a bra and breast cancer risks among post-menopausal women. The researchers, Lu Chen, Kathleen E. Malone and Christopher I. Li, did not find any evidence that wearing a bra is associated with either invasive ductal carcinoma or invasive lobular carcinoma, two of the most common forms of breast cancer. This means it doesn’t matter what bra you wear, your cup size or how long you wear a bra — none of these lead to cancer.

The American Cancer Society has also backed up this claim. The website states that there has only been one study to suggest that there is a risk between breast cancer and bra wearers, however “breast cancer risk in the two groups was not significantly different, according to standard statistical criteria, and the researchers themselves expressed uncertainty regarding this correlation.” The American Cancer Society also notes that regardless of a woman’s weight, there is no convincing evidence that her bra will put her at risk for breast cancer.

That being said, it’s so, so important for women of all ages to conduce self-exams, and to visit their physicians yearly, more if you have a family history of breast cancer. The National Breast Cancer Foundation has a great step-by-step how-to for self examination.
