To clarify, Barrett's cells are NOT cancerous. In fact, there is a less than 1% chance that they will develop into cancer cells and that is only if the underlying cause goes untreated. Fix the problem causing the Barrett's cells and the Barrett's cells will disappear and normal esophageal tissue will return in its place.
I had out of control reflux that on my first endoscopy, showed I had a good sized 7cm ring of Barrett's cells very visible. Changing my prescription reduced it to 3cm a year later. I've since had the nissen Fundoplication procedure and am just about a year out and am hoping that my next scope shows they've disappeared.
