IIRC, jobs found the cancer at it's earliest stage, which has an 80% 5 year survival rate if treated. [1]
Pancreatic cancer tends to move fast and survival plummets as it advances.
*Edit* looks like jobs did in fact undergo treatment for his cancer back in 2004. He didn't go though chemo, but IDK if that'd make the difference. [2]. I need to not be so critical of him, it's likely he did actually listen to medical advice and I simply fell for a common incorrect Internet meme.
Idk what about that abcnews link makes you think you fell for misinformation. Jobs getting a surgery close to the discovery of the cancer doesn't contradict him not following doctors' advice to use chemotherapy. He spent 7 years attempting to just eat fruit to fight off a mostly curable cancer, and it didn't work.
I was under the impression that Jobs did nothing for his cancer. He did, in fact, have it surgically removed.
He further underwent several surgeries for various problems after the pancreatic cancer diagnosis.
It's not clear to me that a doctor wouldn't have advised against chemo for the pancreas. Chemo doesn't always get recommended for cancer treatments (especially now-a-days) and it's not shocking to me that a doctor would potentially recommend against it in his case (super early detection with apparently successful surgery).
A little bit like how if you get skin cancer the first line of defense is to simply lop the thing off. You almost never get chemo with skin cancer unless it has progressed.
The current 5 year survival rate for pancreatic cancer detected early is 80%. So it's definitely an aggressive cancer even in the best practical scenarios.
Back when Jobs got cancer and the media were discussing it I clearly remember reading that with that type there's higher than 90% death rate.
