In Europe and the United States, colorectal cancer is listed as the second cause of death in cancer. Most relapses occur within 5 years after surgery. Gold proposes carcinoembryonic antigen (CEA) as a tumor marker for colorectal cancer. Since 1978, CEA scintigraphy has been used to scan patients for radiolabeled CEA antibodies and to detect scintigraphy in colorectal and other CEA-expressing tumors. Austria Klos
