Can fish oils help fight prostate cancer?

Fish oils could help in the battle against prostate cancer, new research suggests.  Scientists have discovered a mechanism by which omega-3 fatty acids prevent the growth and spread of prostate cancer cells.
However the findings are at odds with a 2013 study asserting that omega-3s increase the risk of prostate cancer. Despite this, the new research 'points the way to more effective anti-cancer drugs,' the researchers claim. 
Scientists have long known that omega-3s reduce inflammation and have anti-diabetic effects, and some recently discovered how this happens.
'But we're the first to show that they work this way in cancer,' said Kathryn Meier, a professor of pharmacy at Washington State University.   'The attention has mostly been on inflammation and diabetes but there has always been an interest in cancer, and we were the first to show this mechanism in any cancer cell at all. And we're using prostate cancer, which is the most controversial subject in omega-3s.'
A 2013 study in the Journal of the National Cancer Institute found that men with higher levels of omega-3 fatty acids in their blood had a greater risk of developing prostate cancer.
