Above all, one should stay on a HEALTHY diet. In my opinion, without that, you can do all the Miracle-Mineral-Supplement , Indian Herb etc you want, but you won't get rid of the cancer. The body MUST have the right nutrition and not have to take in toxins all the time.
Good luck - and don't believe that 4 month figure. This will only be a insidious 'placebo effect'. The mind is very powerful. People believe the authority (doctor in this case) and they will die spot on; on that very same day the doc predicted. Don't believe it. Believe in health instead. KNOW that you will be healthy.
