That's nonsense !
First, there is no cure for pancreatic cancer. Secondly, 75% of all those who develop the disease, die within just a matter of weeks/months after diagnosis; Steve Jobs lived 7 years after pancreatic cancer was detected - which is very rare indeed.
I suggest you read his autobiography by Walter Isaacson. He had a rare and very treatable form of the disease but put off getting it medically treated for all sorts of "cures" that were offered him. Art Levinson, the Chairman of Genentech, and Andy Groves , the Chairman of Intel who had had prostate cancer, fought to get him to get medical treatment rather than eating "horseshit and horseshit roots". In time he came to admit he had made a mistake going for them and if he had had it medically treated early on instead there is a good chance he would be alive and cured today.
