American researchers say men who have been recently diagnosed with prostate cancer can help keep their disease at bay by taking brisk walks.
Writing in the journal Cancer Research, the researchers say men who power walk for at least three hours a week can halve how much their cancer will grow and spread in the next couple of years, the BBC reports.
The researchers say strolling does not have the same effect.
But they say the findings should be interpreted with caution because the men who did more walking also tended to be younger, leaner, and non-smokers, which could also explain some of the differences seen.
The University of California San Francisco study looked at the outcomes of 1455 men, mostly in their 60s, who were diagnosed with localised prostate cancer, meaning it had not yet started to spread.
