Dressed to Kill

Do bras cause breast cancer? Singer and Grismaijer have collected striking evidence that bra-wearing may be a major causal factor for breast cancer. According to the results of their 1991-93 Bra and Breast Cancer Study, described in this book, women who wear tight-fitting bras 24 hours a day are 125 times more likely to have breast cancer than women who do not wear bras at all. Why would bras be linked to breast disease and cancer? It has to do with the effect of bras on breast circulation, specifically the effect of bras on the lymphatic system.
