Thanks for posting your query.
I am Dr.Ratnakar Kini, Gastroenterologist and I am pleased to answer your question.

IBS is a functional disease and it does not increase the CEA level.

A raised CEA indicate many conditions like ulcerative colitis, pancreatitis, certain cancers like colon cancer. Even smoking can cause raised CEA levels.

CEA is never used to diagnose cancer, but only to assess the outcome and response to treatment.

Since you have had inflamed colon earlier, I would suggest a repeat colonoscopy be done to rule out ulcerative colitis.

I hope that answers your question.
