My guess is they were checking to make sure that’s all it was. Heartburn can be a sign of esophageal cancer and a CT scan should pick a tumor, if there was one.
Barrett’s Esophagus is a pre cursor to cancer so yeah I guess it was a good idea to check..besides, the schmuck is a heavy smoker isn’t he..so that raises his risk as well
I think if he did have cancer, they would keep it secret. It would make him even more of a lame duck, if that is possible, and he would not be able to handle it emotionally.
