A carcinoid tumor often causes no symptoms in its early stages and is usually found unexpectedly by a surgeon during an unrelated surgery or on x-rays for another condition. Below you will find possible signs and symptoms of GI carcinoid tumors, lung carcinoid tumors, carcinoid syndrome, and carcinoid crisis. However, the cause of a symptom may be another medical condition that is not a carcinoid tumor.
