Anastrozole is a medication commonly used in the treatment of breast cancer, particularly in postmenopausal women. It functions as an aromatase inhibitor, blocking the conversion of androgens to estrogens, thereby lowering estrogen levels in the body. This reduction is crucial in treating estrogen receptor-positive breast cancer, where estrogen fuels tumor growth.
