Dietary Fat May Influence Prostate Cancer

Article excerpt

Researchers investigating the role of fatty acids in the aggressiveness of early-stage prostate cancer have found that higher concentrations of polyunsaturated fat are linked to less aggressive tumor growth.

"Research has shown that populations with a low-fat diet have lower rates of prostate cancer, although studies about the types of dietary fat have had mixed results," said Mohsen Meydani, D.V.M., Ph.D., director of the Vascular Biology Laboratory at the Jean Mayer U.S.D.A. Human Nutrition Research Center on Aging at Tufts University.

"Our study, which relied on tissue samples rather than patient recall of dietary fat intake, found that there is a probable link between polyunsaturated fat intake and a slower growth of cancer."

The study, led by Vincent Freeman, M.D., of the University of Illinois at Chicago, measured the level of fats in prostate tissue from men with localized prostate cancer. Tissue specimens were collected from 196 men and were analyzed for their concentration of fats.

Men with less advanced prostate tumors had higher concentrations of overall polyunsaturated fatty acids and particularly high concentrations of omega-3 fatty acids compared with men who had more advanced tumors. …
