How effective is anastrozole (arimidex) for treating breast cancer?

Good: it is a very good drug in preventing breast cancer relapse in patients who have had their breast tumors removed. prevents estrogen stimulation in patients with estrogen receptor positive breast cancer.

Many: There are many support groups for pancreatic cancer. The biggest organization is the American Cancer Society but the PANCAN organization has lots of good information and can direct you to a group near you.

Only Postmenopause: Anastrozole inhibits the aromatase enzyme which in turn prevents the conversion of androgens to estrogens in peripheral tissues which is the primary source of estrogen in post-menopausal women. This is very effective and has different and potentially less side effects than Tamoxifen. In pre-menopausal women, the ovaries are still producing estrogen and thus these medicines will not be effective
