White blood cell transplant is proven to shrink (cure) cancer. However you won't see it in the USA for the next XX years. Some doctors in China is already doing it though, so if you can travel, that is an option.

Also, I believe there is an organization that helps cancer victims by arranging travels outside of USA for innovative treatments, LEF can refer you to them.
