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.
