Pancreatic cancer is one of the tough ones. It's a silent one that tends to kill quickly by the time you have a diagnosis.

For patients who get an early diagnosis, the average survival time is 3 to 3.5 yrs. About 10% of those who get an early diagnosis will become disease free after treatment.

Steve Jobs lived 8 years. Michael Landon died within 3 months. Patrick Swayze made it for just under 2 years.

As a royal, if he's been taking advantage of that health care, he agould have caught it early which will improve his odds. He'll also have top not h treatment that the average person doesn't have. That'll improve his odds too. Still. If it was found in any stage beyond stage 1, you'll see a decline rather quickly.
