I've been where you are and the really good news is that after chemo and radiation, the tumor in my esophagus was gone. But it took a while for all the side effects like coughing, spitting up mucus, and being very tired to go away.
I was on feeding tube with ISOSOURCE canisters for several months. There were some good signs early on such as the tumor shrinking 30%. My wife Charlotte was an amazing care giver. I hope you have someone to help you through this ordeal? We wish you well, and will be happy to try and answer any questions you have.
