Steve Jobs knew better

In October 2003, Jobs was diagnosed with cancer. In mid-2004, he announced to his employees that he had a cancerous tumor in his pancreas. The prognosis for pancreatic cancer is usually very poor; Jobs stated that he had a rare, much less aggressive type, known as islet cell neuroendocrine tumor.

Despite his diagnosis, Jobs resisted his doctors' recommendations for medical intervention for nine months, instead relying on a pseudo-medicine to try natural healing to thwart the disease. According to Harvard researcher Ramzi Amri, his choice of alternative treatment "led to an unnecessarily early death". Cancer researcher and alternative medicine critic David Gorski disagreed with Amri's assessment, saying, "My best guess was that Jobs probably only modestly decreased his chances of survival, if that." Barrie R. Cassileth, the chief of Memorial Sloan Kettering Cancer Center's integrative medicine department, said, "Jobs's faith in alternative medicine likely cost him his life.... He had the only kind of pancreatic cancer that is treatable and curable.... He essentially committed suicide."

TL;DR: Jobs had treatable cancer, chose head massage, herbal tea and whale music over medical science.
