Anastrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It functions as an aromatase inhibitor, effectively reducing estrogen levels in the body, which can slow or stop the growth of certain types of breast tumors. Proper dosage is crucial for maximizing its effectiveness while minimizing potential side effects.
