Symptoms of Colon and Rectal Cancer 

The following can be symptoms of cancer of the colon and rectum. However, in their early stages, colon and rectal cancer and pre-cancerous colorectal polyps (or growths) may cause no symptoms. Screening tests can detect colon and rectal cancer at its earliest, most treatable stage. It is important to consult your doctor if you experience any of these symptoms:

• A change in bowel habits, such as diarrhea or constipation, a feeling that your bowel is not emptying completely, or a narrowing of the stool
• Rectal bleeding or finding blood in your stool
• Feel bloated or full
• An enlarged abdomen
• Feel exhausted most of the time
• Start losing weight for no known reason
• Are nauseous or vomiting
