Aromatase inhibitors are medications primarily used in the treatment of hormone-sensitive breast cancer in postmenopausal women. They work by blocking the enzyme aromatase, which is responsible for converting androgens into estrogens, thereby reducing the levels of estrogen in the body. This can help slow or even stop the growth of certain types of breast tumors that require estrogen to grow.
