Steve Jobs refused to undergo what could have been a potentially life-saving surgery to remove a tumor.

Or so says Walter Isaacson, who is the author of the upcoming Steve Jobs biography.

Isaacson told CBS's 60 Minutes that Jobs' was that he didn't want [his] body to be opened and that he didn't want to be violated in that way, reports Gizmodo.

Gizmodo cites how this coincides with Jobs' spiritual beliefs as a Buddhist.

Isaacson said, 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 wanted to talk about it, how he regretted it....I think he felt he should have been operated on sooner.

Instead, reports CNET, Jobs attempted to treat it with alternative medicine.

Jobs had a very rare, very deadly form of pancreatic cancer.

Pancreatic cancer is the fourth leading cause of cancer-related deaths in the United States. It is called the silent killer because of how hard it is to detect. The cancer embeds deep in the abdomen and symptoms are often not visible until late into the development.

His wife and family supposedly urged him to undergo the surgery. Jobs ultimately received the operation in 2004, but apparently it was too late at that point.

The biographer said that Jobs regretted his decision to delay the surgery.

Isaacson, a writer and President and CEO of the Aspen Institute, has been working on the Jobs biography since 2009. He has written other best-selling biographies about Benjamin Franklin and Albert Einstein.

Jobs lost his battle with cancer at 56-years-old on Oct. 5, 2011.

The biography by Isaacson will be released on Oct. 24.
