Anastrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. As a non-steroidal aromatase inhibitor, it works by reducing estrogen levels in the body, which can help slow or stop the growth of certain types of breast tumors. Understanding the appropriate dosage of anastrozole is crucial for effective treatment and minimizing side effects.
