Are men less likely to get breast cancer because antiperspirant gets caught in their underarm hair and is not absorbed by their skin?
Men are much less likely than women to develop breast cancer, mostly because men have much less breast tissue than women. Women have about 100 times more breast tissue than men and are about 100 times more likely to develop breast cancer. Hormones also play a role. Men with metabolic or genetic conditions that lead to increased estrogen levels have an increased risk of developing breast cancer. Underarm hair and antiperspirant absorption have not been linked to male breast cancer risk.
