Increasing the risk of developing colon cancer in men is associated with a daily habit, namely watching TV for more than 4 hours per day. For the purpose of the study, published in the British Journal of Cancer, the researchers used data from about 500,000 adults, whom they watched for 6 years.
Overall, it was observed that men who watched TV for more than 4 hours per day had a 35% higher chance of developing the disease than those who did not exceed one hour. In contrast, no correlation was found among women. On the other hand, men with the highest levels of physical activity were found to have a 23% lower chance of developing the disease.
As reported by the researchers, observed correlations may be explained by both the prolonged sitting time, which is a major risk factor for the onset of the disease, and by the fact that increased viewing may lead to higher consumption of “unhealthy” foods shown on it.
In conclusion, they remind that it is already known that maintaining healthy body weight, limiting alcohol, exercise and high consumption of fruits and vegetables can help reduce the risk of colon cancer.
