Symptoms of Colon Cancer
In the early stages of the disease, symptoms of colon cancer don't usually appear. Once the cancer has progressed, however, symptoms may include abdominal discomfort, blood in the stool, fatigue, constipation, diarrhea, and a change in the frequency of bowel movements. Pain is not normally one of the colon cancer symptoms.
As with many cancers, there are usually no symptoms of colon cancer in the early stages of the disease. That's why colon cancer screening is so important. If diagnosed and treated in its early stages, colon cancer is highly curable.
Once symptoms of colon cancer do develop, they may include:
- A change in bowel habits
- Blood (either bright red or very dark) in the stool
- Diarrhea, constipation, or feeling that the bowel does not empty completely
- Stools that are narrower than usual
- Frequent gas pains, bloating, fullness, or cramps
- Weight loss for no known reason
- Feeling very tired
Final Thoughts on Symptoms of Colon Cancer
Because other health problems can cause these same symptoms, you should talk to your healthcare provider if you are experiencing one or more of these possible symptoms of colon cancer.
Also, early symptoms of colon cancer do not include pain. It is important not to wait to feel pain before seeing a healthcare provider.
