My uncle died from Pancreatic Cancer in 2005. You can battle that shit all you want, but it will kill you in the end. Unc went through so much treatment, had it cut out (cause you can go with half that shit), and it came back and spread to other organs. They offered him more treatment, but he was tired of being sick all the time and said no...died not long after that.
My prayers go out to him and his family, 'cause he's not going to win this battle.
