A Florida man with no medical training has invented a machine that he believes may lead to a cure for cancer. John Kanzius ... wondered if his background in physics and radio could come in handy in treating the disease from which he suffers himself. After 24 rounds of chemotherapy, the former broadcaster decided that he did not want to see others suffer trying to cure the disease. Kanzius said it was watching kids being treated that affected him the most. Particularly, young children walk in with smiles, and then you'd see them three weeks later and their smiles had disappeared. I said to myself, 'We're in a barbaric type of medicine." Kanzius said his machine basically makes cells act like antennae to pick up a signal and self-destruct. Unlike current cancer treatment, Kanzius' machine does not use radiation, and unlike today's radio-frequency treatments, it's noninvasive. Now, some of the nation's most prominent doctors and scientists are using Kanzius' machines in their research. In January, researchers said they performed a breakthrough at the M. D. Anderson Cancer Center in Houston. "The complete killing of pancreatic cells in laboratory conditions is encouraging," Dr. Steve Curley said. Kanzius explained that his machine uses a solution filled with nanoparticles, which measure no more than one-billionth of a meter. A test subject would be injected with either gold or carbon nanoparticles, which would make their way through the body and attach to the cancerous cells. The test subject would then enter the machine and receive a dose of radio frequency waves, theoretically heating and killing the cancerous cells in moments and leaving nearby cells untouched.
