Anastrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing the amount of estrogen in the body, thereby helping to slow or stop the growth of certain types of breast tumors that require estrogen to grow.
