Letrozole is a medication that is primarily used as a treatment for breast cancer in postmenopausal women. It belongs to a class of drugs known as aromatase inhibitors, which work by decreasing the amount of estrogen produced in the body. This is crucial in the treatment of hormone receptor-positive breast cancer, where estrogen fuels the cancer’s growth.
