You failed to mention how did you use the zapper and how many times. Dr. Clarke treatment stated that zapping kills the cause of the cancer. Stopping the malignant is another thing to do. If an organ is been affected by a cancer. Zapping removes the cause of the cancer but the sick or affected organ still need to be healed. Your tumor might still be there but what it causes has been removed. It is your responsibility to treat the tumor with other treatment. However, in some cases, the body's immune system is good and the tumor shrinks almost after zapping. Noe that it is NOT the zapping that shrinks the tumor but it's your body healing itself. If your immune system is weak, then it will take longer for your tumor to shrink or go away after zapping.
