What is an atypical carcinoid tumor?

Are neuroendocrine tumors benign or malignant?

Neuroendocrine tumors can develop anywhere in the body, but most occur in the digestive tract, pancreas, rectum, lungs, or appendix. They can be non-cancerous (benign) or cancerous (malignant). They usually grow slowly over many years, but there are fast-growing forms.

What is the difference between typical and atypical carcinoid tumor?

Do carcinoid tumors metastasize?

Carcinoid tumors usually metastasize to the liver, lymph nodes and lungs (3). In approximately 10% of cases, the primary tumor site remains unknown (4).
