Tools for the diagnosis of colorectal cancer

A series of keyed illustrations (collated here as an animated gif) showing:

1. The main organs of the abdomen;
2. Flexible sigmoidoscopy - allows visualisation of about a third of the colon;
3. Colonoscopy - allows visualisation of the entire colon and rectum;
4. Double contrast barium enema.

FOBT, Fecal Occult Blood Test (right) - detects blood in the stool.

These illustrations are here slightly reduced from the intended size for online usage.
