The risk of developing bowel cancer could be reduced by taking just half an hour's exercise a day, it has been suggested.
Professor Annie Anderson from the University of Dundee noted that the physical activity does not even need to be taken at one time.
The chief nutritional advisor to Bowel Cancer UK said: "It doesn't have to be 30 minutes starting at 14:00 BST and finishing at 14:30 BST.
"It could be two 15 minute periods in a day, for example going to work and getting off the bus stop early, making it a good brisk 15 minutes to work and then coming home again, 15 minutes back to the bus stop."
She added that it is about being as physically active as possible during every day of the week.
Since 1975 the incidence of colon cancer within Europe has increased.
According to a special issue of the European Journal of Cancer, the disease comprised 13.6 per cent of the continent's cancer burden in 2008.
This made it the second most common cancer within Europe.
