Signs and Symptoms

Colon cancer may not show any signs or symptoms in its early stages. Symptoms may include:
  • Blood in or on the stool
  • Diarrhea and/or constipation or other change in bowel habits
  • Narrow stool
  • Weight loss with no known cause
  • Abdominal pain, cramps, tenderness or bloating
  • Tiredness
  • A feeling that your bowel does not empty completely

Having one or more of these symptoms does not necessarily mean you have colon cancer, but you should consult with your family doctor.
