What is a Colonoscopy (ko-lun-AH-skuh-pee):

What is a Flexible Sigmoidoscopy (sig-moid-AH-skuh-pee):
A procedure in which a doctor can look into the rectum and the descending portion of the colon for polyps or other abnormalities.
What is a Double Contrast Barium Enema (DCBE):
A method used to help diagnose colorectal cancer. Barium sulfate, a chalky substance, is infused through the rectum to partially fill and open up the colon. When the colon is about half-full of barium, air is inserted to cause the colon to expand. This allows x-ray films to show abnormal changes in the colon. Also called barium enema with air contrast.
