According to an
article published in the Journal of Nutritional Biochemistry, HER-2 positive
cancer is an extremely aggressive form of breast cancer that affects 25 percent
of women. HER-2 is a growth promoting protein found on all breast cells, and
breast cancer cells with excessive amounts of HER-2 are considered HER-2
positive (American Cancer Society). 
Professor David Ma from the University of Guelph states there are indications
that omega-3 fatty acids are ‘protective against cancer’. The article explains
that there are three different types of omega-3 fatty acids, which include
a-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid
(DHA). The article also clarifies that ALA is the plant-based omega-3 from
seeds and oils, whereas, EPA and DHA are omega-3s found in aquatic organisms
such as fish, algae, and phytoplankton.  Professor
Ma states, “”It’s known that EPA and DHA can inhibit breast tumour growth,
but no one has looked directly at how effective these omega-3s are compared to
ALA.”  Therefore, Ma decided to complete
a study comparing plant-derived and marine-derived omega-3s and their
respective effects on HER-2 breast cancer tumor growth. The study was conducted
by giving mice either plant-based or marine-based omega-3 fatty acids. The omega-3s
were given to the mice before any tumors had developed.  Ma concluded that marine-derived omega-3s are
‘eight times more effective’ in suppressing tumor development and growth. The
mice given the EPA and DHA omega-3s had thirty percent less tumors, and the size
of the tumors was decreased by sixty to seventy percent.  Ma goes on to explain humans would need to have
two to three servings of fish per week to incur the same benefits and notes that
EPA and DHA supplements would provide similar outcomes in cancer prevention. The
professor hypothesizes that the benefits of the marine-based omega-3s on this type
of cancer presumably means other types of cancers would incur similar benefits.
