letrozole, or exemestane with or without chemotherapy works in treating patients with
invasive breast cancer. Estrogen can cause the growth of breast cancer cells. Hormone
therapy, using tamoxifen citrate, may fight breast cancer by blocking the use of estrogen by
the tumor cells. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, may
fight breast cancer by lowering the amount of estrogen the body makes. Drugs used in
chemotherapy work in different ways to stop the growth of tumor cells, either by killing the
cells or by stopping them from dividing. It is not yet known whether giving tamoxifen
citrate, anastrozole, letrozole, or exemestane is more effective with combination
chemotherapy in treating patients with breast cancer.
