Hemoccult testing, however, should be done annually. Polyps that are found should be removed by colonoscopy exam. If the tumor has spread into the lymph nodes, liver or lungs, then chemotherapy treatment is utilized for control. In rectal cancer, radiation therapy is used along with surgical resection. Colon polyps can be detected and removed by colonscopy, an instrument with a lighted tube that allows for the complete examination of the colon.
Early detection is key to better treatment for colo-rectal cancer.
Future approaches include new radiographic techniques that better detect blood in the stool and greater genetic testing to determine risk factors. Much already is known about genetics testing for colo-rectal cancer and polyps, especially in familial types. In addition, new chemotherapeutic regimens and methods to prevent polyps and cancer are being studied. Dr. Harrison W.
