CHICAGO (Reuters) - Statin drugs prescribed to lower cholesterol levels and increasingly seen as having other health benefits have no effect on women's risk of developing breast cancer, a study said on Monday.

Some previous studies have suggested statins may protect against cancers of the breast, colon, pancreas, esophagus and liver, according to the report published in the Oct. 24 issue of the journal Archives of Internal Medicine.

But an analysis of data from 79,000 women participating in the Nurses' Health Study found no link between use of the best-selling drugs and breast cancer.

Of 3,177 breast cancer cases included in the 12-year study, 1,727 of the women took statins, which are designed to lower elevated blood cholesterol levels linked with heart disease.

One theory is that statins may help ward off breast cancer because cholesterol in the blood, and body fat in general, increase production of estrogen, a hormone associated with a heightened risk of breast cancer.

Statins also lessen inflammation and can slow the growth of certain types of cells -- both factors credited with the drug's beneficial effects on bone growth and the vascular system that in turn may retard the development of Alzheimer's disease.

Writing in the journal Archives of Internal Medicine, Eliasson called for further studies, especially on the effect of long-term statin use.
