Rare digestive system tumors form in organs that are important for digesting food and drinks. These organs include your esophagus, stomach, intestines, liver, and pancreas. The cancer may be named by the organ (liver cancer or stomach cancer) or by the type of cell it looks like (neuroendocrine, squamous cell, or stromal cell).
Some of the rare digestive system tumors that affect children, teens, and young adults are:
- Appendiceal cancer
- Cholangiocarcinoma
- Esophageal cancer
- Fibrolamellar hepatocellular carcinoma
- Gastric adenocarcinoma and proximal polyposis of the stomach (GAPPS)
- Hereditary diffuse gastric cancer (HDGC)
- SDH-deficient gastrointestinal stromal tumor (GIST)
The digestive system is made up of many organs that can form tumors
