Symptoms

Colorectal cancer first develops with few, if any, symptoms. However, if symptoms are present, they may include:

  • Blood in or on the stool
  • A change in bowel habits
  • Stools that are narrower than usual
  • General, unexplained stomach discomfort
  • Unexplained weight loss

These symptoms can also be associated with many other health conditions. If you have any of these symptoms, discuss them with your doctor. Only your doctor can determine why you're having these symptoms.
