Steve Jobs’s biographer, Walter Isaacson, said in an interview released Thursday that Jobs did not allow surgeons to perform a potentially life-saving surgery on his pancreatic cancer. Jobs instead chose to try alternative therapies and waited nine months before finally getting the operation. Isaacson said he asked Jobs why he didn’t get an operation sooner and Jobs told him he “’didn’t want my body to be opened … I didn’t want to be violated in that way.’” Jobs relied on fruit juice, acupuncture, and other herbal remedies. Once he opted for conventional surgery and mediation, however, Jobs focused on it like an expert. The biography goes on sale Monday.
