A new study conducted by Washington State University which was published in the Journal of Pharmacology and Experimental Therapeutics in February 2015 found that omega3 fatty acids provide a novel mechanism for the suppression of cancer cell proliferation and in essence inhibit the growth and spread of prostate cancer cells. This finding challenges a 2013 study which claimed omega3s increase the risk of prostrate cancer. These results are very encouraging but the researchers caution that although promising, more research on dosage required is needed to confirm the efficacy of such a treatment.
