Role of Arimidex and How It Works
Breast cancer growth may be estrogen dependent. It is important to suppress estrogen for this reason. Aromatase is the principle enzyme in the body that converts androgen to estrogen in postmenopausal women. Arimidex is a medicine that inhibits aromatase that then prevents the formation of estrogen and keeps the estrogen levels in the blood minimized.
