Colon Cancer: Symptoms

  • Early colon cancers and pre-cancerous polyps often don’t cause any symptoms. This is why getting screened, before you have symptoms, is so important.
  • Screening helps to detect early colon cancer when it’s highly curable. Screening can also help to prevent colon cancer by finding and removing potentially pre-cancerous polyps before they turn into cancer.
  • When symptoms do develop, they may include any of the following:
    • Rectal bleeding.
    • Change in bowel habits.
    • Narrowing of stool.
    • Abdominal pain.
    • Unexplained fatigue (a very tired feeling).
    • Unexplained weight loss.
  • These symptoms can be those of colon cancer or of another gastrointestinal condition or illness. If you have any of these symptoms, please see your doctor for evaluation.
