Just two more hours of sitting at your desk at work or kicking back in front of the TV is linked to a higher risk of several types of cancer -- that's according to a study published this week in the Journal of the National Cancer Institute.
Researchers looked at more than 40 previous cancer studies that involved more than four million people to measure how cancer and sitting are linked.
They found that those two extra hours of sedentary behavior was linked to:
An eight-percent increased risk of colon cancer
A 10-percent increased risk of endometrial cancer
And a six-percent increased risk for lung cancer.
One bright spot -- researchers did not find a link between sitting and all types of cancer, including breast and prostate cancer.
Of course the study doesn't say that sitting causes cancer and there are other factors, like smoking, heavy drinking, and being overweight that can also increase your risks of getting cancer.
