QUESTION: Dear Dr. Tjonneland, Did you take into consideration the intake of 'farmed' fish, which we know offers more Omega-6 rather than Omega-3 essential fatty acids? Or are you lucky enough in Denmark to eat actual ocean fish? If ocean or wild fish, what do you attribute this finding to? May we see your complete paper? We are a patient organization providing information, education, advocacy and awareness for people with cancer, family and friends. RESPONSE: Dear Ann F A lot of the fat fish eaten in Denmark (i.e. salmon) is farmed, however we did not find any difference in risk comparing fat and lean fish. But I think your aspect of Omega-6 and Omega-3 is a very interesting one. In our study among Danish postmenopausal women, we find that women with a high intake of fish, have a higher risk of developing breast cancer. However, as we also state in the paper, only a single study before us has shown a positive association between a high fish intake and breastcancer, but several studies has shown no association. More studies are definitely needed before any firm conclusions can be made. Also regarding our finding that the increased risk was restricted to estrogen receptor positve cancers. What seems to be the current evidence to be drawn at the moment, is that fish intake does not have any protective effect against breast cancer.I don't think that we have evidence at the moment to recommend that women in general or women with brest cancer should avoid fish.
