Fish Oil Does Not Prevent Cancer
posted 1/26/06
A systematic review published in this week's
JAMA shows that fish oil does not prevent cancer.
The review analyzed the results of 38 prior
studies of the effect of fish oil on the risk
of cancers of the breast, colon, lung, prostate,
skin, and other sites. Individual study results
varied. Some showed increased risk from fish
oil, others showed reduced risk, and most showed
no effect. The combined result was that fish
oil has no evident protective effect against
cancer.
