There was only one time he spoke about his brush with death. He used it as a subject for a speech at Stanford's 2005 graduation.
He told those gathered about the day his doctor told him to "get his affairs in order." He said that was code for "you're going to die."
At the time of that speech, Jobs thought he had beaten the disease, but he told the graduates that "no one wants to die."
He used his story to encourage the class of 2005 to pursue their dreams and look for the opportunities in life, which he said could include death itself.
He called death a destination we all share and no one has ever escaped it. He said that "is as it should be because death is very likely the single best invention of life. It's life's change agent that clears out the old to make way for the new."
He told the grads that in 2005 they were the "new" but warned they would soon become the "old." He encouraged them not to waste the life they had.
The entire speech is inspirational, but that part about death comes in at 11:45.
