Carcinoid tumors, which are one subset of tumors called neuroendocrine tumors, usually begin in the digestive tract (stomach, appendix, small intestine, colon, rectum) or in the lungs. Carcinoid tumors often don't cause signs and symptoms until late in the disease. Carcinoid tumors originate from neuroendocrine cells, and they can grow anywhere in your body.
These tumors sometimes secrete hormones, which are your body’s chemical messengers, that can cause symptoms. Most neuroendocrine tumors develop in the digestive (gastrointestinal) tract. A carcinoid (also carcinoid tumor) is a slow-growing [1] type of neuroendocrine tumor originating in the cells of the neuroendocrine system. In some cases, metastasis may occur.

Carcinoid tumor (or just carcinoid) is an older term for certain well-differentiated NETs.

Learn about the causes, symptoms, diagnosis, and treatment of carcinoid tumors, a type of cancer that can show up in many different places in your body.
carcinoid rash, About 12,000 people in the United States will be diagnosed with neuroendocrine tumors — sometimes called carcinoid tumors — each year. But what exactly are these tumors, where are they typically found and are they cancerous? Carcinoid tumors are endodermal in origin and arise from enterochromaffin cells of the aerodigestive tract. GI carcinoids occur most frequently in the small bowel, followed by rectum, appendix, and stomach. Carcinoid tumors are slow-growing and can occur in the lungs or digestive tract. They are more common in Black people than in White people, especially Black men.
