Chronic pancreatis or pancreatic cancer?

It would be unusual to have either at your age, but it would show up on CT if you have one. You poor thing, you have already been scoped everywhere possible I would think I CT would have been done. A CA-19-9 is used as a tumor marker for pancreatic cancer and it only would have been run if your doctor asked for it and it is unlikely he did as he would have had to suspect it to order it. You could try keeping a diary of everything you eat, drink and do and keep track of which pains you have and when, it may make it easier to find what it is that is causing your problems. Good luck.
