In brief: Causes for GI cancer
There are some genetic predispositions to them. Small intestine tumors are rare and probably missed.
Colon cancer is associated to a low fiber diet, associated to colon polyps and more common in the industrialized word. Gastric cancer is more common in volcanic regions :japan, iceland, chile, c.R., smoked food intake ( nitrites) and were refrigeration of food is not adequate, and h. Pylori present.
