Long-Distance Running and Its Potential Link to Increased Colon Cancer Risk
A small, preliminary study suggests that very high-volume endurance training in young athletes may be associated with an increased risk of precancerous colon lesions, raising questions about the potential risks of extreme endurance exercise. While exercise generally reduces cancer risk, extreme training might cause bowel stress, warranting cautious interpretation and further research. Athletes should monitor symptoms like blood in stool and consult healthcare providers, but overall, the benefits of regular exercise remain clear. Future guidelines may include earlier screening for high-volume athletes if findings are confirmed.
