Gastrointestinal
neuroendocrine tumors
(carcinoid)

Gastrointestinal neuroendocrine tumors, known as GI NET, are also called carcinoids or carcinoid tumors. They are a type of neuroendocrine cancer that starts in different parts of your digestive system, called the gastrointestinal (GI) system. The GI system includes the stomach, small intestine, colon, and rectum.
Gastrointestinal system

Most of the time, gastrointestinal neuroendocrine tumors (carcinoids) are small and may be hard to find. Sometimes they are found during other procedures like a colonoscopy or surgery for other conditions.

It may be difficult for doctors to diagnose a carcinoid or neuroendocrine tumor in your GI tract. This is because they can cause symptoms that make them seem like other GI diseases such as irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD).
