Types of Small Bowel Tumors
Small bowel tumors can be either malignant or benign. Malignant types include adenocarcinomas, neuroendocrine tumors (NETs), lymphomas, and sarcomas. Benign forms consist of adenomas, leiomyomas, and lipomas. NETs are now the most common malignant small bowel tumors.
Epidemiology: The Rarity of Small Bowel Cancer
Despite the small intestine being a large part of the digestive system, small bowel malignancies are rare, accounting for less than 5% of GI tract cancers in the US. The incidence of small bowel cancer is rising, mainly due to increased cases of NETs.
Symptoms: What to Look Out For
Common symptoms include abdominal pain, weight loss, nausea, vomiting, and gastrointestinal bleeding. These symptoms are often vague, leading to delayed diagnosis when the disease is more advanced.
