For most, a cancer diagnosis can be devastating. But for John Kanzius it was a call to action. Kanzius isn't a doctor. He doesn't even have a college degree. Yet ... the device he invented has impressed a notable researcher and inspired his hometown, Erie, Pa., to the point where it gave him a key to the city in April. Asked by [a reporter] what made him think he could cure cancer, Kanzius replied with a laugh, Nobody else was doing it! I envision this treatment taking no more than a couple of minutes or so." Kanzius hopes cancer treatments could work something like this: A patient would be injected with tiny metal nano-particles, which would be carried through the bloodstream by a targeting molecule and attach only to cancerous cells. The patient would then be exposed to an energy field created by radio waves, and feel nothing, while the nano-particles would generate enough heat to destroy their cancerous host cell. Kanzius demonstrated just how easily the nano-particles could be used as receivers. A lab worker injected carbon nano-particles into a specific spot in a piece of liver, which was then placed into an energy field of low frequency radio waves. Within seconds, the areas injected the with nano-particles were heated to the point of actually cooking the liver, while leaving the surrounding meat unscathed. Kanzius' invention has caught the attention of Dr. Steven Curley, a surgical oncologist and cancer researcher at MD Anderson Cancer Center in Houston. "This has the most fascinating potential I've seen in anything in my twenty years of cancer research," Curley [said]. Curley has developed current methods of using radio frequencies to attack cancer, but says he looks forward to one day using a non-invasive approach like the one Kanzius is working on.
