Overview Symptoms Treatment Prevention
Colon cancer
Alternative Names: Colorectal cancer; Cancer - colon Symptoms: With proper screening, colon cancer should be detected BEFORE the development of symptoms, when it is most curable. Text Continues Below Most cases of colon cancer have no symptoms. The following symptoms, however, may indicate colon cancer: Diarrhea, constipation, or other change in bowel habits that does not resolve Blood in the stool Unexplained anemia (anemia in any adult who is not a menstruating woman should almost always be evaluated by a colonoscopy) Abdominal pain and tenderness in the lower abdomen Intestinal obstruction Weight loss with no known reason Stools narrower than usual Signs and tests: A physical examination rarely shows any abnormalities, although an abdominal mass may be present. A rectal examination may reveal a mass in patients with rectal cancer, but not colon cancer. A colonoscopy or sigmoidoscopy may reveal evidence of cancer. However, only colonoscopy (NOT sigmoidoscopy) examines the entire colon. Page:  1 | 2 | Next >>
