A provocative claim by a Harvard cancer researcher:

Steve Jobs had a mild form of cancer that is not usually fatal, but seems to have ushered along his own death by delaying conventional treatment in favor of alternative remedies, a Harvard Medical School researcher and faculty member says. Jobs’s intractability, so often his greatest asset, may have been his undoing.

“Let me cut to the chase: Mr. Jobs allegedly chose to undergo all sorts of alternative treatment options before opting for conventional medicine,” Ramzi Amri wrote in an extraordinarily detailed post to Quora, an online Q&A forum popular among Silicon Valley executives. “Given the circumstances, it seems sound to assume that Mr. Jobs’ choice for alternative medicine has eventually led to an unnecessarily early death.”
