I found this article on the UPMC(University of Pittsburgh Medical Center) web site. This is research presently being done that is showing that Omega 3 Fatty Acids can inhibit the growth of liver and cholangiocarcinoma cancer cells and decrease the level of beta-catenin which has been linked to tumor development. Just go to their website and plug in cholangiocarcinoma in the top search box. This study and other info will come up. My husband is starting on flax oil and fish oil capsules tomorrow.
