Obesity can be a major cause of breast cancer in postmenopausal women, but omega-3 fatty acids have the potential to lower that risk. A study done by Andrea Manni, professor and division chief of endocrinology, diabetes and metabolism, Penn State College of Medicine, showed protection comes from the anti-inflammatory effects from the fatty acid.
Breast density is a breast cancer risk. Manni’s team, in addition to researchers from Emory University and Colorado State University examined the influence of prescription omega-3 supplements on breast density in women of various weights. It is believed that women who are of a higher breast density are more likely to develop breast cancer. Researchers found that increasing the level of omega-3 acids in blood was connected with reduced breast density in women bordering obesity with a body mass index above 29. With this research, a personalized approach to breast cancer prevention can be established.
