Sitting is linked to 8 more cancers

Sitting for hours on end is linked to nine more cancers than we thought, according to the cancer expert who is helping to re-write the exercise guidelines.

Charles E Matthews, an epidemiologist at the National Cancer Institute, warns we need more physical activity than we thought - but more importantly, we need to sit less.

Just one hour of TV a day puts even the most active of us at a higher risk of not just breast and colon cancer - which we already knew - but also nine other cancers including lung and head or neck.

Sharing the new research at a conference on Saturday, Dr Matthews said swapping your Netflix show for a brisk walk or some housework could be a game changer.
