Arimidex Helps Shrink Breast Cancer Tumors

Some women with breast cancer may have another treatment option outside of undergoing a mastectomy. It lies in a new class of hormone drugs called aromatase inhibitors, British researchers report. In the study of nearly 300 women, those who took the aromatase inhibitor Arimidex were significantly more likely to become candidates for breast-conserving surgery than those who took standard tamoxifen, said Ian Smith, MD, of Royal Marsden Hospital in London.
