According to biographer Walter Isaacson on '60 Minutes' (Sun., 7PM ET on CBS), Steve Jobs reluctance to be cut open earlier in his struggle with cancer may have cost him that battle. "He regretted it, some of the decisions he made," Isaacson said. "And certainly I think he felt he should have been operated on sooner."

Instead, Jobs went with spiritual treatments and changes to his diet. It took nine months of prodding from those closest to him to convince Jobs to go in for the surgery, but by then it was too late for the procedure to save him.

Isaacson said that Jobs struggled with faith, which may have impacted his decision-making process. Sometimes he believed in God, and other times he believed in a sort of cosmic on/off switch.

"Click and you're gone," Jobs said, according to Isaacson. "And that's why I don't like putting on/ off switches on Apple devices."
