Letrozole is a medication commonly used in the treatment of breast cancer, especially in postmenopausal women. As an aromatase inhibitor, it works by reducing estrogen production in the body, which can help halt the growth of certain types of breast tumors that rely on estrogen to thrive. While it is widely used in oncology, understanding the full scope of its effects is crucial for patients and healthcare providers alike.
