Anastrozole is a medication primarily used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. This medication operates as an aromatase inhibitor, which means it impedes the conversion of androgens into estrogens, subsequently lowering estrogen levels in the body. The adjustment of estrogen levels is critical for controlling the growth of estrogen-responsive tumors.
