To start with, according to World Health Organisation, nearly 16 percent of overall deaths in the world occurs because of cancer. Almost every family has at least one person who has been recorded to have cancer. Furthermore, the cost of cancer in 2010 was approximately 1.16 trillion dollars. In this article, we are mainly going to focus on preventing cancer. Some of the prevention measurements which are generally known include a lowering of alcohol consumption, stopping tobacco smoking, regular exercising etc.

Marine fish oil is more potent than plant-based n-3 polyunsaturated fatty acids in the prevention of mammary tumors” is a study which mainly focuses on prevention measurements for HER-2 breast cancer. This study is published in the Journal of Nutritional Biochemistry with professor David Ma as a leading author. 

The study was organized in nourishing mice with 3 different types of omega-3s. The types of this omega-3s fatty acids are eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and a-linolenic acid (ALA). DHA and EPA are omega-3s fatty acid found in fish, phytoplankton and algae meanwhile ALA are fatty acids found in seeds such as flaxseed as well as in soy oil, hemp and canola oil.

Researchers provided mice with these fatty acids even before cancer development in order to also analyze the prevention efficiency. Then they analyzed and came into conclusion that the treatment with omega-3s fatty acids resulted in a reduction of overall cancer number by 30% and most importantly a reduction of cancer’s size by 70%. In comparison to sea-based omega-3s, there were needed higher doses of the ALA to show the same effect. Omega-3s tend to obstruct the pathways through which cancer spreads as well as it activates some genes correlated with the immune system.

As professor Ma confirmed for the University of Guelph, apparently DHA and EPA are way more effective at HER-2 cancer compared to ALA. he continues that:

In North America, we don’t get enough omega-3s from seafood, so there lies an opportunity to improve our diet and help prevent the risk of breast cancer.

According to the research’s leading author, people should eat up to three portions of fish per week. This study has now paved the way for future research about the effects of omega-3s on other types of cancers.
