His biographer, Walter Isaacson, is going to be on 60 Minutes Sunday night, the day before the biography on Jobs is released. In the clip 60 Minutes has released, Isaacson asked Jobs about his delay in treatment. Apparently, it was a decision he came to regret. The below is a post from MacRumors on the topic http://www.macrumors.com/2011/10/20/steve-jobs-regretted-early-decision-to-delay-cancer-surgery/
With Walter Isaacson's authorized biography of Steve Jobs set for release next Monday, tidbits from the book have been surfacing from time to time. But the most significant revelations to become public ahead of the book's launch will come on Sunday, when an interview with Isaacson airs on the CBS show 60 Minutes. CBS is offering a brief preview of the segment, which will reveal that Jobs regretted an early decision to delay surgery for his pancreatic cancer back in 2004.
"I've asked [Jobs why he didn't get an operation then] and he said, 'I didn't want my body to be opened...I didn't want to be violated in that way,'" Isaacson recalls. So he waited nine months, while his wife and others urged him to do it, before getting the operation, reveals Isaacson. Asked by [60 Minutes correspondent Steve] Kroft how such an intelligent man could make such a seemingly stupid decision, Isaacson replies, "I think that he kind of felt that if you ignore something, if you don't want something to exist, you can have magical thinking...we talked about this a lot," he tells Kroft. "He wanted to talk about it, how he regretted it....I think he felt he should have been operated on sooner."
Isaacson goes on to note that Jobs continued to receive cancer treatments after his surgery, even as he was playing down the seriousness of the issue and telling people that he had been cured. By the time of his surgery, the cancer had already spread beyond his pancreas to the surrounding tissues, suggesting that earlier surgery that could have caught the cancer before it spread might have given Jobs a much better chance.
