Tamoxifen
This medication blocks estrogen receptors in breast tissue and is widely used to treat and reduce the risk of hormone receptor-positive breast cancer in both women and men. It is typically taken as a daily tablet for five to ten years as part of a long-term cancer prevention or treatment plan. Regular gynecologic check-ups are recommended because it can have estrogen-like effects on the uterus.
