In the Daily Mail:
Spending ten years or more in a sedentary job almost doubles the risk of some types of bowel cancer, a study shows.
The research also backs up earlier studies which showed men who sit down most of the day at their jobs are 30 per cent more likely to be diagnosed with prostate cancer than those with very active occupations.
But the latest study, by a team of experts at the University of Western Australia, show long periods of physical inactivity during the day could also be a major risk - even among those who do a lot of exercise in their free time.
Recent studies from the US suggest adults now spend around 55 per of their time at work sitting down.
