C'mon, this is from the National Enquirer. Not the most reputable source of factual news... I for one am not going to give much credence to this at the moment!
They were actually in the running for a Pulitzer in investigative reporting last year. They can be surprisingly accurate. They're a tabloid, yes, but it's not like it can be denied that Jobs is sick. And the NE got it right when they said Swayze was being treated for cancer at the same center that Jobs is now at.
(But I wouldn't bet a large amount of BTC on this)
