Anastrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It works by lowering estrogen levels in the body, which can slow or stop the growth of certain types of breast tumors that require estrogen to grow. Proper dosing is crucial to ensure the effectiveness of treatment while minimizing side effects.
