Carcinoid Syndrome is a group of symptoms that occur in some people with carcinoid tumors, which are a type of slow-growing cancer that usually starts in the digestive system. These tumors can release hormones, particularly serotonin, into the bloodstream, leading to various symptoms. Common symptoms of Carcinoid Syndrome include flushing of the skin, diarrhea, and wheezing. These symptoms can significantly affect a person's quality of life. Diagnosis often involves blood tests to measure hormone levels and imaging studies to locate the tumors. Treatment may include surgery, medications, or other therapies to manage symptoms and control tumor growth.
