Sylvester/UMHC is the first provider in Florida and one of only a handful in the world to offer one of the newest weapons for fighting cancer — NanoKnife™. Our interventional radiology experts use this new minimally invasive treatment to destroy soft-tissue tumors, particularly those that have spread to the liver, kidneys, and lungs. NanoKnife uses a targeted approach to treating small, hard-to-reach tumors at the cellular level. It works by applying electrical energy directly into tumors. This opens the cell walls of the tumor; the cancer cells die; and healthy tissue remains unharmed. Because NanoKnife causes few side effects or scarring, treatments can be repeated if new lesions develop. Download a printable NanoKnife™ Factsheet.
