Fish oil supplements may prevent skin cancer.

Skin cancer is a major public health concern, and the majority of cases are caused by solar ultraviolet radiation (UVR) exposure, which suppresses skin immunity. Omega-3 PUFAs protect against photoimmunosuppression and skin cancer in mice, but the impact in humans is unknown. *

A new study published in The American Journal of Clinical Nutrition, revealed that consuming regular doses of fish oils increases immunity to sunlight in humans.

Professor Lesley Rhodes, Professor of Experimental Dermatology from the Photobiology Unit Dermatology Centre at the University's School of Medicine and Salford Royal NHS Foundation Trust, said their study was the first of its kind conducted using humans:

"There has been research in this area carried out on mice in the past but this is the first time that there has been a clinical trial directly in people. It has taken a number of years to get to this stage and the findings are very exciting. This study adds to the evidence that omega-3 is a potential nutrient to protect against skin cancer. Although the changes we found when someone took the oil were small, they suggest that a continuous low level of chemoprevention from taking omega-3 could reduce the risk of skin cancer over an individual's lifetime."
