Aromasin (exemestane) ) lowers estrogen levels in postmenopausal women, which may slow the growth of certain types of breast tumors that need estrogen to grow in the body.
Aromasin is used to treat early and advanced breast cancer in postmenopausal women. Early breast cancer is cancer that has not spread outside the breast. Advanced breast cancer is cancer that has spread to other parts of the body.
Aromasin is sometimes given after you have taken tamoxifen for 2 or 3 years, or if tamoxifen did not work or has stopped working.
