Carcinoid tumors are a slow-growing cancer that can arise in several places throughout your body. Carcinoid tumors, which are one subset of tumors called neuroendocrine tumors, usually appear in the gastrointestinal tract (appendix, stomach, small intestine, colon, rectum) and in the lungs.

Carcinoid tumors often don't cause signs and symptoms until late in the disease. Carcinoid tumors can produce and release hormones into your body that cause signs and symptoms such as diarrhea or skin flushing.

Treatment for carcinoid tumors usually includes surgery and may include medication.
