Letrozole

Letrozole is a medication commonly used to treat hormone-sensitive breast cancer in postmenopausal women. It works by lowering the levels of estrogen, a hormone that can promote the growth of certain breast tumors. By reducing estrogen, letrozole helps slow or stop the growth of these cancers. It’s also sometimes prescribed off-label to help increase fertility in women with specific hormonal imbalances. The medication is taken orally and is usually well-tolerated, though it can cause side effects like hot flashes, joint pain, or fatigue. Overall, letrozole is an important drug for managing certain types of breast cancer.
