Can constipation cause colon cancer?

Constipation is a common symptom in the elderly and is also one of the culprits for inducing cerebral hemorrhage and heart attack. Recent studies have also found that constipation may cause colon cancer. American scientists reported this result in the latest issue of the monthly journal "Epidemiology". They found that the incidence of colon cancer in people with constipation is more than 4 times that of normal people. They believe that frequent constipation may be the main factor for colon cancer in middle-aged and elderly people. The reason is that constipation causes excrement to stay in the colon for too long, and the colon absorbs too much carcinogens in the excrement. Therefore, preventing constipation can not only reduce the occurrence of emergencies such as cerebral hemorrhage, but also prevent colon cancer. Specific measures are: ① Develop good living habits, work and rest regularly, prevent excessive mental stress, and develop the habit of regular bowel movements. ② Change bad eating habits, eat more vegetables and fruits, eat more foods rich in plant fiber, and eat less meat. ③ Regularly participate in sports to promote intestinal peristalsis. ④ Constipation should be treated in time, such as taking fruit laxative tablets and using enema.
