Steve Jobs had a kind of pancreatic cancer with an excellent long-term prognosis, but he delayed his surgery for 9 months, instead taking alternative therapies like vegan diets, coffee enemas, herbal remedies, accupuncture, juice fasts, bowel cleansers, and other such unproven treatments. When assessed months later, it was found that his tumour had grown and spread. He then had the surgery, but by then the cancer was in his liver.
