Although the small intestine is approximately twice as long as the esophagus, stomach and colon together, tumors of the small bowel are relatively rare. They account for about 25% of all tumors of the digestive tract. The reason for this apparent immunity is a matter of conjecture; it is presumed that the lack of stasis in this part of the digestive tract is significant. In the absolute sense, however, tumors of the small intestine cannot be considered rare. They are found in about 20% of autopsy material. In contrast to the colon and especially the esophagus and stomach, where malignant tumors are more common than benign ones, only one-fifth of all tumors in the small intestine are malignant.
