Colon and Rectal Cancer Causes

  • Polyps – growths on the inner lining of the colon or rectum:
    • Adenomatous polyps (adenomas)
    • Hyperplastic polyps and inflammatory polyps
  • Dysplasia – an area in a polyp or the colon or rectum lining where cells appear abnormal

 

Colon and Rectal Cancer Symptoms

Colon and Rectal Cancer Screening

Routine screening, recommended for almost everyone at age 50, is key to colorectal cancer prevention. Tests include:
  • Flexible sigmoidoscopy – performed to examine the interior walls of the rectum and part of the colon
  • Colonoscopy – performed to examine the interior walls of the rectum and colon
  • Double-contrast barium enema – an X-ray test that highlights the inner part of the colon and rectum
  • Computed tomography (CT) colonography, or virtual colonscopy – creates a 3-D view of the colon and rectum  
  • Fecal blood tests – stool samples collected by patients using a kit and returned to the doctor. The tests look for hidden blood:
    • High-sensitivity fecal occult blood test (FOBT)
    • Fecal immunochemical test (FIT)
