What are the risks of hormone therapy for menopause?
Like any treatment, hormone therapy is not free of risk. In women with a uterus, using estrogen alone can increase the risk of endometrial cancer because estrogen causes the lining of the uterus to grow. Taking a progestin along with estrogen will help reduce the risk of uterine problems. The drawback of using a progestin is that it seems to increase the risk of breast cancer. Also, menopausal women may start bleeding again. Although bleeding may occur only for a short time, many women find this bleeding bothersome.
