“In early 2009, the tech and investing worlds were trying to untangle a puzzle about Apple. The company was putting out incredible devices, but it was unclear why the legendary leader wasn’t there,” Doron Levin reports for Fortune.

“Jobs had surgery for pancreatic cancer in 2004, taking a leave of absence to recover. He had returned, only to disappear a few years later, a second medical absence for roughly six months in 2009. How sick was he? And what did he have? It wasn’t until June 20th, two months after the fact, that the Wall Street Journal uncovered the fact that Jobs had undergone a secret liver transplant at Methodist University Hospital in Memphis, Tennessee,” Levin reports. “However, during that absence, Fortune can report, Jobs also took an unpublicized flight to Switzerland to undergo an unusual radiological treatment at the University of Basel for neuroendocrine cancer, according to Jerry York, the Apple director who died in March 2010.”

MacDailyNews Take: Jobs didn’t “disappear” in 2009 He told the world he was taking a medical leave of absence and then he took it.

Levin reports, “York told me about the treatment, which was not available in the U.S., in the context of our discussions about Jobs, his health and Apple’s future. Under our agreement at the time, York wanted the facts of Jobs’s treatment in Switzerland to remain out of the news. He didn’t say whether the board knew of it. (With York’s death, the off-the-record agreement is no longer in place.) …While York told me he didn’t know exactly why Jobs and his doctors had sought medical care in Switzerland, it is the home for the world-renowned University Hospital of Basel, which has developed a special form of hormone-delivered radiotherapy to treat neuroendocrine cancer. The treatment isn’t available in the U.S. “
