Aromasin, also known as exemestane, is a medication used to treat breast cancer in postmenopausal women. Exemestane belongs to a class of drugs called aromatase inhibitors. It works by reducing the amount of estrogen in the body, thereby slowing down the growth of certain types of breast tumors.
Aromasin is used in certain circumstances to treat early and advanced breast cancer. In the case of early breast cancer, the cancer is only present in the breast, while in advanced breast cancer, cancer has spread to other parts of the body. It can be highly effective in treating cancers that depend on estrogen to grow and spread.
