Gastrointestinal bleeding is not always easy to detect. Bleeding can come from any part of digestive tract, from mouth to the rectum. It can be from small amount that is only detectable by laboratory testing, to massive bleeding that can cause hemorrhagic shock. Benign small-bowel tumors may develop as a single lesion or as multiple lesions of several sub-types.
