Surgical doctors are touting the use of NanoKnife for tumor removal. The device is a new use of nanotechnology, the science of dealing with particles and dimensions down to the atomic level. The NanoKnife is a series of needle-like steel probes with an electrical generator, a computer with monitor and a couple of foot pedals to operate it. The "nano" aspect of the procedure is that the electrical pulses poke infinitesimal holes in the tumor's cellular walls, causing them to die naturally and be routinely discarded by the body. Doctors hope that, because of its precision, the NanoKnife will be more likely to remove an entire tumor, leaving the patient cancer-free. They also say it's easier on patients than previous methods, the Miami Herald reports.
