During an adenoma colonoscopy, the doctor inserts a thin, long, flexible tube called a colonoscope into the rectum with a video camera at its tip to exam the entire colon. The doctor may then collect tissue samples and remove the abnormal growths or polyps during the procedure. Unlike with other examinations such as a sigmoidoscopy, a doctor can clearly view the details in the colon and lower parts of the small intestine. Doctors can find areas of inflammation, tumors, ulcers and colon polyps easily with an adenoma colonoscopy, says WebMD.

With an adenoma colonoscopy, doctors explore the causes of rectal bleeding, chronic diarrhea, abdominal pain, chronic constipation and other colon-related problems. This procedure is crucial, especially for individuals 50 and above, and doctors recommend at least one examination every 10 years. However, there are a few risks during the procedure, such as tears in the colon, reaction to the sedative and bleeding from a biopsy site, notes Mayo Clinic.
