Understanding Letrozole Effects: Benefits and Risks

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 reducing the amount of estrogen the body makes, which can help slow or stop the growth of certain types of breast tumors that require estrogen to grow.
