Men who exercise daily could halve their risk of prostate cancer, a major study has found.
Experts said regular activity – which can include gardening or walking – has a “far larger” protective effect than previously thought.
A team funded by the World Cancer Research Fund (WCRF) and Cancer Research UK used a robust method of measuring physical activity among 79,148 men with prostate cancer and 61,106 without.
The study, which mainly involved men over the age of 50, found those that were the most active had a 51 per cent reduced risk of prostate cancer compared with those who were the least active.
Researchers compared the 16 per cent who were most active with the 16 per cent who were most sedentary.
The most active men would be expected to meet NHS guidelines which recommend around 2 and a half hours exercise weekly, or 20 minutes a day.
In the UK, around one in six men will be diagnosed with prostate cancer during their lifetime.
The WCRF said this risk could drop to one in 12 for men who are the most physically active.
Dr Sarah Lewis, senior lecturer in genetic epidemiology at Bristol Medical School and lead author of the research, said: “Our findings suggest that the more active you are, the better.
“We would recommend that men are as physically active as they can be.
“Our evidence suggests being active will be beneficial in terms of their prostate cancer risk.
