My wife was recently diagnosed with a astrocytoma tumor grade III. I am very interested in the Dr. Clark method. Her tumor was inoperable because of the location of the tumor. How are things going on your front? It is good to hear that you guys have had success. A lady in our Church kept talking about a "zapper" I wonder if it is the same. Do you know if Dr. Clarks book is available at the normal book stores?
