In oncology, small intestine cancer, also small bowel cancer and cancer of the small bowel, is a cancer of the small intestine. It is relatively rare compared to other gastrointestinal malignancies such as gastric cancer (stomach cancer) and colorectal cancer.[1]
Small intestine cancer can be subdivided into duodenal cancer (the first part of the small intestine) and cancer of the jejunum and ileum (the later two parts of the small intestine). Duodenal cancer has more in common with stomach cancer, while cancer of the jejunum and ileum have more in common with colorectal cancer.
Several different subtypes of small intestine cancer exist. These include:
- adenocarcinoma
- gastrointestinal stromal tumor
- lymphoma
- ileal carcinoid tumor
Risk factors
Risk factors for small intestine cancer include:[2][3]
- Crohn's disease
- Celiac disease
- Radiation exposure
- Hereditary gastrointestinal cancer syndromes: familial adenomatous polyposis, hereditary nonpolyposis colorectal cancer, Peutz-Jeghers syndrome
- Males are 25% more likely to develop the disease
