TESTS FOR BOWEL CANCER
Guidelines recommend starting routine screening from age 45 years in order to detect for signs of colon cancer or noncancerous colon polyps and even earlier if there is a family history of bowel cancer or Familial adenomatous polyposis or risk factors.
The benefit of screening is that cancer is detected early, managed and increases the chance of successful recovery and outcomes. Speak to your doctor about the most appropriate screening in your circumstance. The following screening techniques are used:
Computed tomography (CT or CAT) colonography.
Fecal occult blood test (FOBT) and fecal immunochemical test (FIT which is more sensitive and more convenient to carry out)
Stool DNA tests
Chemotherapy, Radiation Therapy, Surgery, Drug Therapy, Targeted therapy and Immunotherapy are all treatment options for bowel cancer. The selection of treatment is made by the doctor based on the type of bowel cancer the patient has, the location of the tumor in the colon and/or rectum, how far the cancer has spread, the speed at which tumors are developing and the overall health of the patient.
