Living with Neuroendocrine neoplasm

A tumor (carcinoid tumor) of hormone-making cells that usually forms in the digestive tract or lungs.

Understanding Neuroendocrine neoplasm

Neuroendocrine neoplasm (carcinoid tumor) is a type of neuroendocrine tumor that usually develops in the digestive tract or the lungs.

It can also develop in other places, such as the pancreas, testicle, or ovary. Symptoms depend on where the tumor is, and may appear only in later stages. A digestive tract tumor may cause symptoms only if it has spread to the liver. Tumors can release hormone-like substances that cause carcinoid syndrome. GARD lists onset in adulthood.

Signs & symptoms

GARD doesn't list a symptom list, but the summary describes these features:

  • Flushing of the face and chest
  • Diarrhea
  • Trouble breathing
  • Coughing or wheezing (lung tumors)
  • Pneumonia (lung tumors)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include cancer specialists and hormone specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Carcinoid Cancer Foundation, GO2 Foundation for Lung Cancer and Neuroendocrine Tumor Research Foundation may keep lists of experts for this condition.
