I agree with your sentiments regarding pancreatic cancer.
One of my mom’s clients (a very wealthy lawyer) got it about three years ago.
Thru a number of experimental trials at the Mayo Clinic, he was able to delay the inevitable for 2 years. He actually led a pretty good life during that time too, relatively free of pain and chemo side-effects. But eventually the cancer got the upper hand and won.
My dad died from this and it only 3 months of horrible and relentless pain.
