Carcinoid tumors are a type of neuroendocrine tumor that can occur in various parts of the body, including the gastrointestinal tract, lung, and ovary. They are slow-growing tumors that produce hormones and other substances that can cause a range of symptoms, including flushing, diarrhea, and heart valve problems. Carcinoid tumors can also spread to other parts of the body, such as the liver, causing symptoms such as abdominal pain and jaundice. Diagnosis is typically made through imaging studies and biopsy.

Treatment options may include surgery, radiation therapy, and chemotherapy. The choice of treatment depends on the size and location of the tumor, as well as the overall health of the patient. It is important to seek medical attention if you experience symptoms that may be related to a carcinoid tumor.
