Tamoxifen is a selective estrogen receptor modulator (SERM) that binds to estrogen receptors, blocking the proliferative action of estrogen in breast tissue. It is widely used in the treatment and prevention of estrogen receptor-positive breast cancer. The drug also exhibits estrogen-like effects in other tissues, contributing to its diverse clinical profile.
