Could Omega-3s Reduce Breast Cancer Risk for Obese Women?

A randomized clinical trial of 266 women who were normal weight, overweight or obese with high breast density suggested that obese women could reduce their risk of breast cancer by taking omega-3 fatty acids. Cancer Prevention Research published the findings.

Inflammation & Obesity

The breast cancer risk is higher in obese women due to the inflammation related to obesity,  according to Dr. Andrea Manni, professor and division chief of endocrinology, diabetes and metabolism at Penn College of Medicine in Hershey, Pennsylvania.

“Omega-3 fatty acids have an anti-inflammatory effect, so that’s one of the reasons why we suspected it may be particularly effective in obese women,” Dr. Manni said

Omega-3s Have Mega Health Benefits

Omega-3 fatty acids can be found in fish oil, and in some nut and plant oils. and are associated with improving cholesterol profiles and reducing the risk of coronary heart diseases.

Inconclusive Past Results

Previous studies have suggested that omega-3 fatty acids may help protect against breast cancer in obese women, although results have remained inconclusive. Dr. Manni suspects data obtained from women with normal weights may have caused this inconsistency.

The aim of the study was to measure the change in the participants’ breast density over two years. High breast density appears to be a risk factor for breast cancer; according to the National Cancer Institute (NCI), women with dense breast have a four- to sixfold increased risk of developing the disease.

“The higher the breast density, the more likely the woman will develop breast cancer,” asserts Dr. Manni.

However, scientists are divided as to why breast density is an independent cancer risk.
