Study: Sitting for too long 'increases cancer risk'

Sitting down for too long increases the risk of certain cancers, as well as heart disease and diabetes, a new analysis suggests.

Every extra two hours spent sitting down was associated with an 8% increase in the risk of bowel and a 6% increase in the risk of lung cancer.

Even in people with active lifestyles, it appears that those who spend a long time sitting were vulnerable to a heightened risk of cancer.

Scientists looked at pooled data from 43 different studies with over 4 million participants to come to their conclusions.

They also suggested sitting in front of the TV was linked to a higher risk of bowel cancer and cancer of the womb lining in women, possibly because of the tendency to consume junk food and fizzy drinks while watching.
