Patient discussion about CN

Q. Cn barret esophagous be cured? I was diagnosed with barretts esophagus several years ago, and so far keeps on the routine follow up. I met some other guy with same condition and he told after his doctor prescribed him with some anti-reflux meds, in the last endoscopy they found normal esophagus, and that he thinks he's now cured. Is that possible?

A. Anti-reflux treatment may lower the risk of cancer a little, but it won't cure it, so there's still a need for refular follow-up.
