Can someone have colon cancer symptoms, but the tumor is not cancerous? is this possible? please help!

Yes, possible. if someone has colon cancer symptoms, its highly recommended to further investigate the condition using colonoscopy with biopsy. Its recommended to do a colonoscopy yearly for people above 50 years old. the size of tumor can be seen using a CT scan.

Some of the common colon cancer symptoms are,
1. Changes in your bowel habits, such as bowel movements that are either more or less frequent than normal,

2. Constipation (difficulty having a bowel movement or straining to have a bowel movement),

3. Diarrhea (loose or watery stools)

4. Intermittent (alternating) constipation and diarrhea,

5. bright red or dark red blood in your stools or black, dark colored, "tarry" stools,

6. Stools that are thinner than normal ("pencil stools") or feeling as if you cannot empty your bowels completely,

7. Abdominal (midsection) discomfort, bloating, frequent gas pains, or cramps.

Yes, it is possible. if you have seen a medical doctor but aren't comfortable with his diagnosis, please get a second opinion. the doctors expect this and are not insulted.
