Cancer of the colon and rectum is the second most common cause of cancer-related death in the United States. Back to Top Therapy Surgery is the standard treatment for colon and rectum cancers and offers the best chance for cure. Successful treatment of colon and rectum cancer is generally related to the size of the tumor and whether it has invaded nearby lymph nodes and vital organs. Resection of local disease includes the surgical removal of all cancer, plus a margin of normal tissue around the site, to ensure that all the disease is eliminated. To aid in the detection of cancer spread, John Wayne Cancer Institute has pioneered a technique in colon cancer called intraoperative lymphatic mapping and selective lymphadenectomy.
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.
