Letrozole belongs to a class of drugs known as nonsteroidal aromatase inhibitors. Letrozole decreases the amount of estrogen in the body. Because many types of breast cancer cells require estrogen to grow, this drug may slow or stop the growth of cancer cells. Letrozole is given as a tablet taken by mouth.
