Singer and Grismaijer have collected striking (but preliminary) evidence that bra-wearing may be a major risk factor associated with breast cancer: 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. Their interpretation is that tight clothing inhibits the proper functioning of the lymphatic system (an internal network of vessels and nodes that flushes wastes from the body) and leads to a buildup of carcinogenic compounds in the constricted areas. Although it must be emphasized that their studies are preliminary, still controversial, and definitely need to be followed up with detailed analyses of correlative factors (do these women have higher rates of smoking? do they have less-healthy diets?), this book should be read by anyone concerned about breast cancer. Possibly a very important book that could save many lives.
