Background on Jobs’ health from the AP:

Jobs had battled cancer in 2004 and underwent a liver transplant in 2009 after taking a leave of absence for unspecified health problems. He took another leave of absence in January – his third since his health problems began – before resigning as CEO six weeks ago. Jobs became Apple’s chairman and handed the CEO job over to his hand-picked successor, Tim Cook.
