[|Human|] helo sir my father is having sist in food pipe. he has gone through endoscopy where doctor suspects it  as a esophagus cancer but we are not seeing any symptoms like problem in swallowing food, pains etc which are forcing us not to rely on the reports of the doctor. kindly guide us what to do?
[|AI|]  Hello you are not sure of the doctors' opinion, you could take a second opinion from other gastroenterologists for confirmation. If you are not having any symptoms How did you findcoutcabout this problem? Some form of cysts at first are very small which wouldn't cause any difficulties in the initial stages but could spread rapidly if not looked into.Thus, if you are not sure about the doctors opinion kindly consult other specialist because it needs to be checked by some clinical tests only, endoscopy being one. Thank you.
