Theories: Of slow bowel activity, build up of bad bacteria creating toxins or toxic environment. And healthy intestinal bacteria with higher fiber diet may cause less colon wall mucosal irritation and less risks for cancer. Also theories of low fat diet and increased exercise lowering colon cancer risks.
