Can be minimal: Unfortunately, colorectal cancer usually gives no symptoms during its early , more curable stages. As it grows, it can cause bleeding which can cause anemia (weakness) blockage causing abdominal pain, nausea and/or vomiting and abdominal enlargement. Most cancers start as benign polyps that can be removed at colonoscopy so screening colonoscopy is important by age 50 in asymptomatic individuals.

Colonic polyps: Nearly all colon cancers arise in colon polyps. Unfortunately, colonic polyps are generally asymptomatic and require colonscopy of barium enema for detection. Newer imaging studies may make the detection easier. Patients with inflammatory bowel disease have higher incidence of colon cancer. A family history of colon cancer is an other "sign".

There can be crampy abdominal pain and a feeling that your bowels are not emptying completely. There may be unexplained weight loss.
