By Mayo Clinic staff

In many cases, carcinoid tumors don't cause any signs or symptoms. When they do occur, signs and symptoms are usually vague and depend on the location of the tumor. Signs and symptoms of carcinoid tumors may include:

  • Abdominal pain
  • Bowel obstruction
  • Changes in bowel movements
  • Chest pain
  • Diarrhea
  • Difficulty breathing
  • Rectal bleeding
  • Rectal pain
  • Recurrent pneumonia
  • Redness or a feeling of warmth in your face and neck (skin flushing)

When to see a doctor
Carcinoid tumors often don't cause any signs and symptoms. If you experience any signs and symptoms that bother you and are persistent, make an appointment with your doctor.
