Rectal Cancer Health Center

A common symptom of colorectal cancer is a change in bowel habits.

Symptoms include:

  • having diarrhea or constipation
  • feeling that your bowel does not empty completely
  • finding blood (either bright red or very dark) in your stool
  • finding your stools are narrower than usual
  • frequently having gas pains or cramps, or feeling full or bloated
  • losing weight with no known reason
  • feeling very tired all the time
  • having nausea or vomiting

Most often, these symptoms are not due to cancer. Other health problems can cause the same symptoms. Anyone with these symptoms should see a doctor to be diagnosed and treated as early as possible.

Usually, early cancer does not cause pain. It is important not to wait to feel pain before seeing a doctor.
