Dressed to Kill is a 1995 book by Sydney Ross Singer and Soma Grismaijer that proposes a link between bras and breast cancer. According to the authors, the restrictive nature of a brassiere inhibits the lymphatic system, leading to an increased risk of breast cancer. Their claim that bras cause breast cancer has been dismissed by the scientific community; major medical organizations including the National Institutes of Health and the American Cancer Society have found no evidence that bra-wearing increases breast-cancer risk.
