I am not a doctor but my boyfriend had pancreatic cancer they were going to do the Whipple surgery but he let his insurance go for some reason and we had a wait to whole year and it was too late so get everything done that you need to get done and then go worry about everything else to have it so just get the surgery done and then worry about everything else that goes with it cuz they be able to tell once they in there and do the surgery and if you already done chemotherapy and stuff that's perfect but just be positive about everything. let me know what happens thank you Debbie
