Carcinoid syndrome is the pattern of symptoms sometimes seen in people with carcinoid tumors. These tumors are rare, and often slow growing. Carcinoid syndrome occurs only 10% of the time, usually after the tumor has spread to the liver or lung. These tumors release too much of the hormone serotonin, as well as several other chemicals that cause the blood vessels to open (dilate). More carcinoid tumors are being diagnosed today than in the past.
