Omega-3 in Fish May Reduce Breast Cancer Risk

 

A large review of studies concludes that women who consume more omega-3 fatty acids by eating fish were at a lower risk of having breast cancer.

The researchers in China analyzed the results of 26 international studies involving almost 900,000 women, including 20,000 who had breast cancer. The scientists found that those women who had the consumed the highest levels of omega-3 fatty acids from fish were 14 percent less likely to have breast cancer, compared with those who ate the least.

The results also showed what researchers call a dose-response relationship: each 0.1-gram increase in omega-3 per day was linked with a 5 percent lower risk of having breast cancer. For comparison, a serving of an oily fish such as salmon contains about 4 grams of omega-3 fatty acids. Oily fish are those that have high concentrations of omega-3.
