Link between omega-3 fatty acids and increased prostate cancer risk confirmed

A second large, prospective study by scientists at Fred Hutchinson Cancer Research Center has confirmed the link between high blood concentrations of omega-3 fatty acids and an increased risk of prostate cancer.

The latest findings indicate that high concentrations of EPA, DPA and DHA -- the three anti-inflammatory and metabolically related fatty acids derived from fatty fish and fish-oil supplements -- are associated with a 71 percent increased risk of high-grade prostate cancer. The study also found a 44 percent increase in the risk of low-grade prostate cancer and an overall 43 percent increase in risk for all prostate cancers.

The increase in risk for high-grade prostate cancer is important because those tumors are more likely to be fatal.

Alan Kristal, Dr.P.H., the senior author of the report that was published on the 11th July in the online edition of the Journal of the National Cancer Institute, and member of the Fred Hutch Public Health Sciences Division is quoted as saying: "We've shown once again that use of nutritional supplements may be harmful."
