Colon Cancer Symptoms
In the early stages, colon cancer often does not show any signs or symptoms. Colon cancer symptoms usually appear after the polyps develop into malignant tumors. This is why, it is important to have regular screening tests, especially after the age of 50, to detect colon cancer early when it is more easily treated.
Common symptoms of colon cancer include:
- Changes in your bowel habits, such as constipation, diarrhea, or a change in the consistency of your stool, that lasts longer than four weeks
- A feeling like your bowel is not completely empty
- Blood in your stool
- Persistent abdominal discomfort, such as cramps, gas or pain
- Loss of appetite
- Weakness or fatigue
- Unexplained weight loss
If you experience the above symptoms and these symptoms last for several weeks, see your doctor immediately to discuss your concerns and arrange for tests to get to the bottom of your symptoms.
Colon cancer that’s found through screening testing is usually easier to treat. Screening can even prevent some colon cancers by finding and removing pre-cancerous polyps.
