Anastrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer, particularly in postmenopausal women. As an aromatase inhibitor, it works by decreasing estrogen production in the body, which can help to slow or stop the growth of certain types of breast tumors that require estrogen to grow. Understanding the appropriate dosage of Anastrozole is vital for effective treatment and to minimize potential side effects.
