For the first time, a scientific study has identified sedentary behavior as a potential risk factor to explain the sharp rise in colorectal cancer among those under 50.

The study, which looked at TV viewing as well as other sedentary behavior in nearly 90,000 American women, found that more than one hour of daily TV viewing was associated with a 12 percent increase in risk of colorectal cancer. Among those watching more than two hours per day, there was a striking 70 percent increase in risk. The results of the study were published Jan. 25 in JNCI Cancer Spectrum.
