How does this medication work? What will it do for me?
Anastrozole belongs to the group of cancer-fighting medications known as antineoplastics, and specifically to the group of antineoplastics known as nonsteroidal aromatase inhibitors. It 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.
Anastrozole can be used after surgery to treat postmenopausal women with hormone-receptor-positive early breast cancer. Anastrozole can also be used to treat postmenopausal women with advanced breast cancer.
