In brief: Endoscopy
Most cancers of the GI tract arise from the inner lining and can be seen and biopsied by upper endoscopy (esophagus, stomach, duodenum) or colonoscopy (colon and rectum).
Small intestine cancers are more difficult to identify, typically found on ct scanning; if there is a high degree of suspicion, a pill-camera can be used to search for these elusive tumors; thankfully, they are rare.
