How painful this must be. How old is Owen? As a dad of a seven year old whose friends six year old passed from a Glioma brain tumor, ireally am at a loss for words. As a pharmacist, I find our work in this area need major improvement. Although I never recommend alternative therapy, if it were my son and we exhausted our options, I may. Someone told me about native American healing recently. I think it was called 13 grandmothers. Google them. Please don't raise false hope but also leave no stone unturned. Best of luck to your family. Pete
