Radiologists at Shands at the University of Florida have used nanotechnology to precisely deliver electrical currents to destroy tumor cells.
It works by using computerized tomography or ultrasound imaging to guide two or more fine-needle electrodes into the tumor. The electrodes deliver high-voltage, pulsating electrical currents that open microscopic pores in the cancer cells, rapidly killing the tumor. After such treatment, the body naturally removes the dead cancer cells.
