Men who intake high ratios of fish oil or omega-3 fatty acids (FAs), especially docosahexaenoic acid and eicosapentaenoic acid, relative to omega-6 arachidonic acid have been found to have a decreased risk of prostate cancer compared to those with low ratios in some but not all case-control and cohort studies. Primary prevention trials with either risk biomarkers or cancer incidence as endpoints regarding the association between omega-3 FA consumption and risk of prostate cancer are studded with controversial results. However, many clinical trials have shown that fish oil could decrease the risk of developing prostate cancer. The anticancer properties of anticancer drugs could be greatly improved when combined with fish oil. We briefly reviewed fish oil and relevant omega-3 FAs as well as early investigations in prostate cancer prevention and treatment.
