Anastrozole is a medication commonly used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. This aromatase inhibitor works by decreasing the levels of estrogen 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 correct dosage of Anastrozole is crucial for effective treatment and to minimize potential side effects.
