Anastrozole is a medication primarily prescribed for the treatment of hormone receptor-positive breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing the levels of estrogen in the body. By lowering estrogen levels, Anastrozole helps to inhibit the growth of certain breast tumors that require estrogen to grow.

Conclusion
