Letrozole: What is it and How Does it Work?

Letrozole is a medication commonly used in the treatment of breast cancer. It belongs to a class of drugs known as aromatase inhibitors, which work by reducing the amount of estrogen produced in the body. Estrogen can promote the growth of certain types of breast cancer, so lowering estrogen levels can help slow or stop the growth of cancer cells.

How does Letrozole work?

Letrozole works by inhibiting the enzyme aromatase, which is responsible for converting other hormones in the body into estrogen. By blocking this enzyme, letrozole effectively reduces the amount of estrogen circulating in the body. This can help prevent estrogen-dependent breast cancers from growing and spreading.

Who can benefit from Letrozole?

Letrozole is commonly prescribed for postmenopausal women with hormone receptor-positive breast cancer. It is often used as part of adjuvant therapy, which is given after surgery to reduce the risk of cancer recurrence. Letrozole may also be used to treat advanced breast cancer that has spread to other parts of the body.

Overall, Letrozole is an important medication in the treatment of breast cancer, particularly in cases where the cancer is estrogen-sensitive. https://letrozolebodybuilding.com/ By reducing estrogen levels in the body, letrozole can help slow the growth of cancer cells and improve outcomes for patients.
