Hi Jersey Girl,
I am sorry to hear about your grandfather, but not to worry, I am sure he will do fine. My prayers to you and your family...
As for the cancer, did they tell you what type of cancer it is? I just finished my second year and although I have not had much clinical experience, we just finished our Gastrointestinal system and were lectured to extensively by an oncologist regarding neoplasms. It all depends on where the cancer originated. If the doctors told you he had Barrett's esophagus, which is a lower esophageal cancer, that is much different than a cancer originating in the upper esophagus which is a squamous cell carcinoma and is the most common (about 90-95% we were told). Barrett's Esophagus is a type of adenocarcinoma which may have a different prognosis and is usually associated with gastroesophageal reflux disease. Overall, prognosis really depends on how much metastasis there is and whether or not there is lymph node invovlement. Usual treatments are surgery or chemo if it is spread to the nodes.
You can read up on the internet about it as well. I may have not helped much, but hopefully I gave you some insight. Of course, I don't know anything yet, so definately have you and your family ask the doctor or doctors to explain to you what type of prognosis your father has.
Maybe post on the rotations and residencies page and ask some of the residents...they should know a lot more than me! Best of luck and take care,
