Hello klee0522, Thank you for posting your query through Healthcare magic. Your question itself contains worry. This is the dangerous part of it. You have to understand that all the changes in your body which we call diseases are defence mechanisms and are not aimed to destroy you. Now come back to the surgical repair of the hiatal hernia. Was it a major surgery. Did you get alarmed at or after the surgery? Did you think it was going to be fatal etc.? Also understand that no surgery is curative. It is only an interference with nature and except in accidents, they are not needed. The surgery done for hiatus hernia could have avoided by right Homoeopathic remedies since childhood. But it became worse and the acid reflux symptoms got worst and disease worsened to a more serious type. So now you are suffering from the sessile polyp. I am not to say that surgery on hiatus hernia caused this . It is a constitutional manifestation and so genetic. Now, my conclusion is that you should not worry about cancer or its fatality associated in your case. What you have to do is to approach an expert Homoeopathic physician at the earliest. In case you do not have one and if you opt to consult me online, I need a lot more information about YOU because in Homoeopathy YOU are being treated and once YOU are cured, all your complaints will get relief. You need not doubt, even the polyp can get regressed and your body and mind will become healthy. I can even send to you a case taking form on request in which you can enter your whole case and forward it to me. I will study it and suggest your curative remedy. With Best Wishes, Dr. C. J. Varghese, Homoeopath, drcjvarghese@gmail.com,
