Letrozole: Description of the Drug and Its Effect on the Body
Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. As an aromatase inhibitor, it plays a significant role in reducing estrogen levels in the body, thereby slowing or stopping the growth of certain types of breast tumors that require estrogen to grow.
