A recent report adds to the growing evidence that omega-3 supplements may play a role in preventing chronic disease.
Researchers asked more than 35,000 postmenopausal women who did not have a history of breast cancer to complete a 24-page questionnaire about their use of supplements.
Regular use of fish oil supplements, which contain high levels of the omega-3 fats EPA and DHA, was linked with a 32 percent reduced risk of breast cancer.
"The reduction in risk appeared to be restricted to invasive ductal breast cancer, the most common type of the disease. The use of other specialty supplements, many of which are commonly taken by women to treat symptoms of menopause, was not associated with breast cancer risk."
