you dont have pancreatic cancer. If you did, you'd be dead already. Sorry to be blunt, but usually pancreatic cancer kills a person in like 6 months. So since you've had these symptoms for a year, well, you're still alive, so you don't have cancer.
Dont pay attention to what you see online. go to those sites and put in any symptom and it will show cancer as a possibility.
Fatty liver disease is no joke. thats probably what you have, so change your diet accordingly and lose the weight like your doctor said and you should feel better.
If you are still worried, get a second opinion. It is not worth it to waste your time by worrying
