What Are the Symptoms?
In its early stage, colorectal cancer usually produces no symptoms. The most likely warning signs include:
- Changes in bowel movements, including persistent constipation or diarrhea, a feeling of not being able to empty the bowel completely, or rectal bleeding
- Dark patches of blood in or on stool; or long, thin, "pencil stools."
- Abdominal discomfort or bloating
- Unexplained fatigue, or loss of appetite or weight
