Tamoxifen is a medication primarily used to treat and prevent breast cancer. It works as a selective estrogen receptor modulator (SERM), meaning it can both block and mimic estrogen in different tissues of the body. This dual action is crucial in the management of hormone receptor-positive breast cancers.
