Fish oil probably does not help prevent cancer

A review study that appeared in Journal of the American Medical Association suggests that fish oil, seen as beneficial for preventing heart disease, may not help prevent cancer. The researchers looked at 38 studies over 30 years. While a few small studies showed improvement for cancers of the breast, prostate, and lung, they were not definitve.

Steve - another "review study." This is a perfect example of trying to make a definitive statement about a substance to which there is scant data. Fish oil for cancer prevention is low on the total pole on our priority list, precisely because the data is much more definitive for its effectiveness for cardiovascular, neurological, and pain /inflammation prevention. Although, we would never say that it "probably does not prevent cancer" because a review study says so. The review study 's conclusion cannot be definitive mainly because of the 38 studies reviewed, many were focused on health issues other than cancer.
