Letrozole is a medication primarily used in the treatment of hormone-receptor-positive breast cancer in postmenopausal women. As an aromatase inhibitor, it works by lowering estrogen levels in the body, which can slow down or reverse the growth of breast tumors that thrive on this hormone. Understanding the effects of Letrozole is crucial for patients and healthcare providers alike.
