Chance that 4 CT scans over 2 1/2 years would all miss sympotomatic colon cancer (narrow stool, occasion blood), also sigmoidscope to 35 cm.

Chance that 4 CT scans over 2 1/2 years would all miss sympotomatic colon cancer (narrow stool, occasion blood), also sigmoidscope to 35 cm.

Fairly high risk: CT scans are NOT good tools for looking inside the bowel. Endoscopy is the preferred tool, but a sigmoidoscopy, at its best, misses looking at half the colon. A look to merely 35 cm has missed about 85-90% of the colon. The usual method to evaluate the colon is a complete colonoscopy. ...Read more

Narrow stools.: Consistently narrow stools imply rectal narrowing. It could be that you have an apple core lesion of the lower GI tract. Also consider very late onset Hirschsprüng's disease or some in lower GI intestinal blockage. You should see a really good GI doc soon and get a good thorough workup and treatment plan. Good luck. ...Read more

I have had narrow stools for over year with small amount of blood. Had 3 CT of abdomen this year. Think it still could be cancer? Gi doesn't seem conce

Colonoscopy?: Did you have a colonoscopy yet? If you haven't then discuss this with your GI docs. That being said, the most common cause of blood in the stools would be hemorrhoids and that may be why the GI doc is not concerned. However, the only way to make sure there is nothing else is to take a look inside the colon with a colonoscopy.
All the best,

Possible lesion: In situ adeno unrelated unless some for of radiation employed that could narrow distal bowel.
