Types of small bowel tumours include:1

Diagnosis

Diagnosis of small bowel tumours involves a number of tests. You may undergo a special x-ray known as a small bowel contrast study or CT enterography (CT imagery with contrast material to view the small intestine), which are used to identify the small bowel mass; or a capsule endoscopy, a procedure involving swallowing a camera-on-capsule which transmits images to an external recorder to examine the small intestine.

Further tests may also be required, often to see if the cancer has spread beyond the bowel or rectum. These include a CT scan, MRI scan or PET scan.2

Treatment

Treatment for small bowel tumours depends on the type that you have, and your age, medical history and treatment preferences. Options include:2
