Omega-3 supplements linked to prostate cancer

A supplement taken by millions for its health benefits may help to trigger aggressive and lethal prostate cancer, research has shown.

Omega-3 fatty acids, derived from fish oils and lauded for their anti-inflammatory properties, were found to increase the risk of high-grade disease by 71%.

Taking omega-3 was also associated with a 44% greater chance of developing low-grade prostate cancer. Overall, the fatty acids raised the risk of all prostate cancers by 43%.
