Letrozole is a medication that belongs to a class of drugs known as aromatase inhibitors. It is commonly used in the treatment of breast cancer in postmenopausal women, particularly those with hormone receptor-positive breast cancer.

By inhibiting the enzyme aromatase, letrozole reduces the production of estrogen in the body. Since estrogen can promote the growth of certain types of breast cancer cells, reducing its levels can help slow down or even stop the progression of the disease.

Letrozole is typically taken orally in the form of tablets, and is usually prescribed for long-term use as part of a comprehensive treatment plan for breast cancer. It is often used either alone or in combination with other medications or therapies, such as surgery, chemotherapy, or radiation therapy.

Common side effects of letrozole may include hot flashes, fatigue, joint pain, and bone thinning. Serious side effects are rare but can include an increased risk of osteoporosis or fractures.
