Cryosurgery uses ultrasonic monitoring to direct a cold probe into the liver tumor.
This freeze-thaw process permanently damages the tumor, causing its cells to die. These tumor cells are gradually reabsorbed by the body. John Wayne Cancer Institute's surgeons are some of the world's most experienced specialists in this innovative technique. They have published their findings in important medical journals. Radiofrequency ablation destroys tumor cells by delivering an electrical current via a needle.
