Carcinoids may grow for a long time without causing any problems. Most patients are diagnosed in advanced stages. This is the most common sign of Carcinoid tumors. This can be triggered by alcohol consumption or emotional distress. It is due to enlargement of the vessels of the skin by chemical stimulation from chemicals released by the tumor.
Diarrhea is also a common symptom.
The constellation of these symptoms in patients with metastatic or widespread Carcinoid tumor is referred to as Carcinoid Syndrome . When suspected, CT scan or Ultrasound examination of the abdomen may establish the site and extent of the disease. A Fine needle aspiration of the Carcinoid may confirm the existence of this cancer. Detection of hormones and chemicals in the blood and urine may also assist in making a diagnosis. A CT scan of the abdomen, as well as bone scans , may be necessary to complete the staging workup.
