Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. It functions as an aromatase inhibitor, which means it works by reducing the levels of estrogen in the body. By lowering estrogen levels, Letrozole helps to slow or stop the growth of hormone-sensitive tumors.
