Yeah, apparently he was doing better for a bit, but there's only so much you can do. Especially with Pancreatic cancer, you only get the symptoms when its too late. My gramps got better for a week or so also, but since the Pancreas is kinda squished in and close to all your other final organs, once it hits the liver; you're done for, and start going through hell on earth. There's like only 4-5% of people that don't die from it, and recover.
Really sad shit.
