I take fish oil every day. does this increase my chances of prostate cancer?

Not yet known...: It is reasonable to be concerned about this in light of a recent study, but correlation does not mean causation and whether fish oil increases risk of prostate cancer is still not known. See http://www.Health.Harvard.Edu/blog/fish-oil-friend-or-foe-201307126467 and http://robbwolf.Com/2013/07/11/prostate-cancer-omega-3-fats/ to learn more about the nuances of this complex issue.

Fish oil prostate : There is no connection between fish oil and prostate cancer. Fish oil is thought to decrease triglyceride levels.
