Most common signs of colorectal cancer

While the following signs are not unique to colorectal cancer and do not mean you have it, they may be cause for concern:

  • Blood in the stool (either bright red or very dark in color)
  • A persistent change in normal bowel habits such as diarrhea, constipation or both, for no apparent reason
  • Frequent or constant cramps if they last for more than a few days
  • Stools that are narrower than usual
  • General stomach discomfort (bloating, fullness and/or cramps)
  • Frequent gas pains
  • A strong and continuing need to move your bowels, but with little stool
  • A feeling that the bowel does not empty completely
  • Weight loss for no known reason
  • Constant tiredness

If you have not had a colonoscopy in the past ten years and notice any of these symptoms, talk with your doctor and make an appointment to have a screening today.

Note that many people diagnosed with colorectal cancer never had any symptoms or early warning signs. Only a colonoscopy can give you the assurance that you are free of the disease.
