How does this medication work? What will it do for me?
Letrozole belongs to the group of cancer-fighting medications known as antineoplastics, and specifically to the type of antineoplastics known as nonsteroidal aromatase inhibitor.
Letrozole can be used after surgery to treat postmenopausal women with hormone receptor-positive early breast cancer, including those who have received approximately 5 years of tamoxifen therapy. Letrozole can also be used to treat postmenopausal women with advanced breast cancer. It can also be used to treat women who have gone through natural or artificially induced menopause who have breast cancer that has spread to other parts of the body and whose cancer has progressed following anti-estrogen therapy.
Letrozole fights breast cancer by inactivating an enzyme known as aromatase. This prevents the enzyme from supplying the estrogen that allows certain types of breast cancers to grow and survive.
