I'm going to chime in here, even though it seems your anxiety is interfering with you ability to think rationally and logically about your situation. A few years ago, I had the worst heartburn ever, almost always at night or after a heavy meal. When I made an appointment with my PCP to check it out (a little background: he has been my doctor for 10 years and he is the funniest guy on the face of the earth, no joke), when he opened the door he threw down my file, made a little megaphone with his hands and announced, "I already know what you're thinking and it's NOT! PANCREATIC! CANCER!!!" After we laughed about it, he did find out that my gallbladder was going south on me. One ultrasound and one laparascopic surgery later and I am as good as new, I promise. I've had none of the scary surgery side effects that people love to talk about. And it might not even be your gallbladder. In your case it could just be killer heartburn. But I would bet so much money on you NOT having pancreatic cancer.
