    Prostate cancer

    The effect of fish oil consumption on prostate cancer is controversial. For instance, one study showed decreased risk with higher blood levels of DPA. However, another reported increased risk of more aggressive prostate cancer with higher blood levels of combined EPA and DHA.Some evidence indicated an association between high blood levels of omega-3 fatty acids and an increased prostate cancer risk. However, this evidence from the Select Trial has been challenged on the grounds of methodology...
