Too Much Sitting May Cause Cancer

Prolonged periods of sitting could lead to an increased risk for breast or colon cancer. A new study suggests as many as 90-thousand new cases of the diseases are caused each year by too much sitting and not enough exercise.  Researchers are urging people with desk jobs to get up and move around for at least one to two minutes every hour.  The research will be presented today at this year's American Institute for Cancer Research conference in Washington, DC.
