13-Year Study Proves Tamoxifen Helps Prevent Breast Cancer

Janice Billingsley, Forbes, November 15, 2005
The final results of a 13-year study confirm that tamoxifen, a drug long used to treat breast cancer, can also prevent the malignancy in healthy women at high risk for the disease. Tamoxifen administered as a preventative measure in a group of 1000 high-risk women reduced occurrence by 43%. There are side effects which must be weighed against the benefits, of course. Tamoxifen's side effects were both beneficial and potentially harmful, and included a 32 percent decrease in bone fractures over seven years of follow-up and an increase in risks for uterine cancer, stroke, pulmonary embolism and cataracts. The findings appear in the Nov. 16 issue of the Journal of the National Cancer Institute.
