Anastrozole is a medication widely used as an aromatase inhibitor in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It functions by reducing the levels of estrogen in the body, which can help slow or stop the growth of certain types of breast tumors that rely on estrogen to grow.
