Vitamin A may be used to prevent prostate cancer, say University of York scientists.
Their research, published in the journal Nucleic Acids Research, showed cancer cells are under control of a derivative of the vitamin, known as retinoic acid, the Daily Express reported.
They believe the research could lead to vitamin A as an anti-cancer treatment and generate new advice for people to ensure they include adequate levels of the nutrient in their diets.
"We hope vitamin A will be used to prevent prostate cancer and we also believe that a derivative of vitamin A could help destroy prostate cancer cells or make them more treatable once they have started to spread.
"Clinical trials based on this research could herald a new dawn in treatment for prostate cancer patients," he added.
But he warned people not to rush out to buy vitamin A supplements, which could be toxic and even cancerous in high doses. Instead he advised people to take vitamin A in their daily diet, including oily fish, carrots, liver, red pepper and dark leafy vegetables.
