Can supplements be used to treat prostate cancer?

Food supplements like vitamins or food products that have certain properties are sometimes marketed as treatments for prostate cancer.  While I am skeptical that the supplements can eliminate prostate cancer completely, I do believe that supplements might improve your immune system’s ability to fight cancer.  Examples of foods that have been suggested as prostate health items include:  Vitamin D-3 (1000-2000 IU per day), Curcumin or Tumeric, and Omega -3 Fish Oil 1000 mg.  Some supplements like Selenium have shown potential harm  in recent studies.  Chinese herbal remedies have been tried by many patients and might have benefits, but I recommend sharing the supplements you use with your physician team to ensure that all medications are safe.
