Where are most carcinoid tumors located?
Carcinoid tumors often grow very slowly. In children and young adults, carcinoid tumors are most often found in the appendix, called appendiceal carcinoid tumors, or in the lungs, called bronchial tumors. In adults, carcinoid tumors are most often found in the digestive tract.
Where do carcinoid tumors spread?
Regional: The cancer has either spread to nearby lymph nodes, or it has grown through the wall of the organ where it started and into nearby tissues such as fat, ligaments, and muscle (or both). Distant: The cancer has spread to distant parts of the body such as the lungs, liver or bones.
Why do carcinoid tumors occur?
Carcinoid syndrome is caused by a carcinoid tumor that secretes serotonin or other chemicals into your bloodstream. Carcinoid tumors occur most often in the gastrointestinal tract, including your stomach, small intestine, appendix, colon and rectum.
What is the origin of carcinoid?
Carcinoid tumors are endodermal in origin, classicallyconsidered to originate from the enterochromaffin cells (ECs; also known as the Kulchitsky cells), which are located in the crypts of Lieberkühn throughout the digestive tract.
Can you see carcinoid tumors on a CT scan?
A CT scan is most often used to look at the chest and/or belly (abdomen) to see if GI neuroendocrine (carcinoid) tumors have spread to nearby lymph nodes or other organs such as the liver. It can also be used to guide a biopsy needle into an area of concern..
Do carcinoid tumors need to be removed?
Because most carcinoid tumors grow slowly and some do not cause any symptoms, completely removing all metastatic carcinoid tumors may not always be needed. But in some patients, surgery to remove all visible cancer is the best option.
How long does it take for a carcinoid tumor to grow?
In general, it can take 3-5 years and even up to 10 or longer for carcinoid tumors to grow. These are generally very slow-growing tumors. How long does the octreotide/radioisotope remain in the body?
Are carcinoid tumors aggressive?
Sporadic carcinoid tumors may be aggressive, with a high incidence of metastases and a 5-year survival rate of less than 75% [48].
What foods to avoid if you have carcinoid tumors?
Avoid foods that contain high amounts of mines, nitrogen-containing organic compounds, as they can trigger the release of serotonin and other hormones. These foods include fatty meats, smoked or salted fish, aged cheeses, and even chocolate. There are other changes you can make to your diet to better manage symptoms.

Can carcinoid tumors be cured?
Most patients with resectable lung carcinoid tumors are cured with surgery alone and don’t need other treatments. Some experts recommend further treatment for people with an atypical carcinoid that has spread to lymph nodes. This can be chemotherapy, radiation therapy, or both.
