Intake of fish and marine n-3 polyunsaturated fatty acids and risk of breast cancer: meta-analysis of data from 21 independent prospective cohort studies

In my forthcoming book, The Layman’s Guide to Surviving Cancer, I discuss, among many things, the potential anti-carcinogenic properties of certain fish oils.  A meta-analysis (a study that synthesizes the results of other studies) published in May 2013 discusses the apparent effects of consumption of certain fish oils and breast cancer risk.  In “Intake of fish and marine n-3 polyunsaturated fatty acids and risk of breast cancer: meta-analysis of data from 21 independent prospective cohort studies,” BMJ 2013;346:f3706, the authors analyzed the findings of 21 studies, covering almost 21,000 cases of breast cancer and more than 880,000 participants, regarding the intake of fish and certain polyunsaturated fatty acids (“PUFA”) and their effect on cancer rates.

Among the meta-analysis’ findings, the authors reported that the results of 16 studies indicated an inverse association between the intake of PUFA and breast cancer.  In other words, intake of marine n-3 PUFA meant a lower incidence of breast cancer among the populations studied.  These effects were seen more prominently in Asian populations, perhaps because fish represent a larger proportion of the diet among such populations.  While leaving firmer conclusions for future research, the authors conclude that “evidence from either experimental or observational studies suggests a protective effect of marine n-3 PUFA on breast cancer.”  Put simply, they found, based on the populations studied previously, that intake of PUFA may lead to a reduced breast cancer risk.

This study is available at http://www.bmj.com/content/346/bmj.f3706.  Check it out and let me know what you think.  In healing,

  1. I leave a comment whenever I like a post on a sitte
    or if I have somethinng to aadd to the discussion.
    Usually it is caused by the passion displayed in the post I browsed.
    Annd on this post Intake of fish and marine n-3 polyunsaturated fatty acids and isk off breast cancer: meta-analysis of data from 21 independent prospective cohort studies – We Can Survive Cancer.
    I wass actually moved enough to create a leave a responsea response :) I do have 2 questioins for you if it’s okay.
    Could it be just me or does it give the impression like a few
    of the responses appear like they are written by brain dead people?

      Hi Seth, thanks for your comments on the article. Right now this site is my primary vehicle for pursuing this mission. When my book comes out, in a couple of months I hope, there will be a separate author’s page on Facebook and I will post information on that on this site so people can cross reference. Thanks for following and best regards.

      Howard
