For over 40 years Barbara Seaman has been a leading women's health advocate. Now she blows the lid off the estrogen industry in this fascinating book that holds the power to improve-possibly even save-women's lives. In America 30 million women take estrogen. Seaman shows that this powerful hormone is hardly the cure-all some claim it is. In fact, estrogen treatments may increase the risk of cancer, heart disease, and osteoporosis.
