If I don’t want to do a colonoscopy, what other procedures are available?

Colonoscopy is the only procedure that screens the entire colon and allows your doctor to immediately remove any polyps or abnormal tissues that may be present. However, other screening options include:
  • Stool exams (Fecal occult blood test): should be done annually. However, if blood is found in the stool, a colonoscopy may still be needed to look for the source.
  • Virtual colonoscopy (CT Colonography): is another colon screening option. However, if a polyp or abnormal tissue is found, you may still need to have a colonoscopy to remove/biopsy it.
  • Sigmoidoscopy is an option to screen the Sigmoid only. However, this procedure does not screen entire colon.
