How does a cryotherapy treatment work?
One or more ultra-thin, 17 gauge (1.47 mm) cryoablation needles are inserted percutaneously (through the skin) directly into the tumor, with no incision. Once inserted into the tumor, the cryoablation needles are cooled to sub-zero temperatures according to a predetermined freezing and thawing protocol. The physician sculpts a freeze zone to engulf and destroy the cancerous area, whether it is the entire prostate gland, kidney tumor or other tumors. Depending upon the treatment, ultrasound, CT and/or MRI Imaging continuously monitors the iceball propagation and ice coverage of the tumor.
