TV watching increases risk of colorectal cancer

A recent study showed that men who watched more than four hours of TV daily had a 35% higher risk of colorectal cancer, compared with those who watched for no more than one hour per day. The study did not find a similar association among women but noted that men with higher levels of physical activity had a 23% reduced risk of colon cancer than men who had lower activity levels. The study suggest that men could lower their risk of colon cancer by increasing their physical activity levels.
Lead researcher Dr. Neil Murphy, of the International Agency for Research on Cancer in France, and colleagues recently reported their results in the British Journal of Cancer.
