Get a full scope.: Most early colon cancers are asymptomatic. The blood on the outside of your bowel movement is likely due to hemorrhoids. Colon cancer is possible, however, and the sigmoidoscopy you had only looked at half of your colon. So to rule out colon cancer, i would recommend a full colonoscopy.
