Vitamin D could reduce the chances of men developing prostate cancer and needing cancer treatment, according to new research.
Findings published in the International Journal of Health Geographics showed that low exposure to the sun could result in vitamin D deficiency, which could lead to men developing prostate cancer.
Rebecca Porter, chief executive of UK charity the Orchid Cancer Appeal, recommended that by eating plenty of oily fish about three times a week, people can ensure that they are getting enough vitamin D.
"There is not always sufficient sunlight around, but vitamin D can be taken through wild oily fish such as mackerel, herring, tuna and cod liver oil," she said.
According to Cancer Research UK, more than 35,000 men in the UK were diagnosed with prostate cancer, making it the most common cancer in men in the UK.
Ms Porter advised men to regularly check for signs and symptoms, such as frequent urination and problems with urination, including "taking a while to get the flow started and getting up at irregular times in the night".
