Q. Is wearing a bra/brassiere a cause for breast cancer? How?
Doctor Answer is medically reviewed by SecondMedic medical review team.
No, wearing a bra is not a direct cause of breast cancer. However, there have been some studies suggesting that tight fitting bras and unnatural shaped bras can have an indirect effect on the development of breast cancer.
A 1996 study conducted by Dr. Sydney Singer and Soma Grismaijer found that women who wore tighter-fitting bras for more than 12 hours a day had an increased risk of developing breast cancer. The researchers determined that this was due to exposure to higher levels of constricting pressure on the lymph nodes in the breasts which can restrict lymphatic drainage from these areas in the body - drainage which aids in flushing out toxins from these regions.
It's important to note that further research has since contradicted this finding and no statistically significant correlation between wearing tight-fitting bras or other types of brassieres and increased risk for breast cancer has been established yet. So while it's always good practice to choose comfortable undergarments made with breathable materials, there is currently no scientific evidence suggesting that wearing a bra increases your risk for developing breast cancer directly or indirectly.
