[|Human|] I am 64.75 years old female and had gastric bypass surgery in 2001 and at the same time I had a hiatial hernia repair (glad that happened).  But as a result of many years of acid reflux, I now have a dammaged esophagus.  I have to use Nitro Lingual Pump Spray to control pain which can occure from stress, differences in temperature of the air I breathe.  I hear there is a way to possibly cauterize the tissue to help repair the esophagus.  Is that something I should look into as a friend said it culd turn into cancer or may have already. I am still over weight , but initially after my gastric bypass I lost 100 0f my 316 pounds.  I am a 6 foot tall woman.  I was experiencing many health disorders because of this and was even using a C-pap.  Which I no longer need.  Later I had to have knee meniscus repair surgery on my left knee and that kept me from exercising and now it is my right knee.  So I have put about 30 pounds back on.  I am working with a knee doctor to try to see if we can fix the right knee now. Primary question is related to my esophagus concern though.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You have acid reflux and hiatus hernia history.  You may have Barrett esophagus which turn Into cancer, or you may have cancer due to chronic irritation.  Furthermore, you should go for endoscopy.  It will give you exact diagnosis whether you have ulcer or mass or some other lesion.  Then you should take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
