menopausal hormone therapy
the use of estrogen (and often progesterone) from an outside source after the body has stopped making its own supply because of natural or induced menopause. This type of hormone therapy is sometimes given to relieve symptoms of menopause. Studies have found that taking estrogen and progesterone together increases breast cancer risk, as well as the risk of heart disease and blood clots, although it might lower the risk of colorectal cancer.
