That, is another matter. I know a few people who's cancer had been declared inoperable but at least a couple of them are still going strong. Years of chemotherapy and radiation has taken away their hair but by God, they are still fighting. I have to admire the courage of these people but it breaks my heart.
I would never completely discount more traditional medical approaches but if I were faced with a grim prognosis from an MD, I'm sure I'd be looking at other alternatives. But I'd go the tradtional route first.
I firmly believe that your state of mind can be one of the best and most effective tools for fighting cancer. A positive approach is not a guarantee of sucess of course but a negative one can be almost guaranteed to work against you.
