I'm not sure you know much about modern cancer treatment.
There are many medical treatment options that DO NOT call for cutting, chemotherapy, or radiation.
If diagnosed and you do your homework (go to a top cancer center for a second opinion), you have a much better chance of survival.
Stanford is a top center out of ten or so in the country.
I've never read that Jobs went to Stanford for treatment.
Jobs used non-medical snake-oil treatments until it was too late.
Steve needed surgery. He delayed it. Apple Stock might have had something to do with the delay in not wanting to shake up the company. He didnt have the same kind of cancer as Swayze.
Jobs needed surgery. He might have lived longer had he gotten surgery sooner.
