Early stages of Colorectal Cancer do not usually have symptoms.
Advanced disease may cause:
- Rectal bleeding or blood in stool
- Change in bowel habits or stools that are narrower than usual
- Stomach discomfort (bloating, cramps)
- Diarrhea, constipation or feeling that the bowel does not empty completely
- Unexplained weight loss
- Constant fatigue
If you feel that you have any of these symptoms, call your doctor immediately. Other conditions such as infections, hemorrhoids and inflammatory bowel disease can also cause these symptoms.
