Dr. Robert Jones is the inventor of the Cavitat ultrasound device used to help locate jawbone cavitations that are responsible for the onset of cancer. He found that toxins from dental cavitations caused a repression of the body's ability to prevent/fight cancer. (see http://breastcancercured.com/gpage42.html ) The head of a cancer clinic in Ecuador (see http://www.breastcancercured.com ), Robert Dowling, has never seen a cancer patient that didn't have cavitation/s in the mouth in the same area containing the same energy (chi) meridians that run to the area of the cancer. He uses the Cavitat to locate the dental cavitations before sending them to a dental specialist to correct the problem. Then he uses my DC Electrifier to shrink the tumor.
