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. The book's claims are considered unfounded by the scientific community, and researchers have criticized the authors' methodology as faulty. 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.
