A report in Cancer Epidemiology, Biomarkers & Prevention showed increasing evidence that fish oil supplements may play a role in preventing breast cancer.
Researchers from Fred Hutchinson Cancer Research Center in Seattle had Emily White, PHD of the public health sciences division survey 35,016 postmenopausal women with no history of breast cancer and asked them in a 24-page questionnaire if they use a “nonvitmain, nonmineral specialty supplements." After six years of following up, "880 cases of breast cancer" were seen using the Surveillance, Epidemiology and End Results registry. The regular use of fish oil containing high amounts of omega-3 fatty acids, EPA & DHA was linked to having a 32% reduced risk in breast cancer. The reduction in breast cancer was linked exclusively to invasive ductal breast cancer (the most common form). The study also shows that women who used supplements to reduce menopausal symptoms did not have an increase risk for breast cancer. Keep in mind that the fish oil used by the women in this study had the right amount of the active ingredients to allow for benefits. In other words, not all supplements are created equal. Some could have more or less of the active constituent.
