Living with Neuroendocrine tumor of pancreas

A tumor, also called an islet cell tumor, that forms from hormone-making cells, usually in the pancreas.

Understanding Neuroendocrine tumor of pancreas

A pancreatic neuroendocrine tumor (NET), also called an islet cell tumor, is a tumor that typically arises in the pancreas.

It arises from cells that make hormones, so the tumor can make hormones too. It may be benign (not cancerous) or malignant (cancerous). Functional tumors cause symptoms by making extra hormones, such as gastrin, insulin, or glucagon. Nonfunctional tumors generally don't cause specific symptoms at first but may later, based on their location and size. GARD lists onset in adulthood.

Signs & symptoms

GARD doesn't list a symptom list. Symptoms depend on the type of hormone made.

  • Symptoms from extra hormones, depending on type
  • Symptoms from tumor size and location

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, digestive system 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

    National Pancreas Foundation and Neuroendocrine Tumor Research Foundation may keep lists of experts for this condition.

InheritanceAutosomal Dominant

Most pancreatic NETs are not inherited and occur in people with no family history. About 10% are linked to a hereditary tumor syndrome such as multiple endocrine neoplasia type 1 (MEN1), which is autosomal dominant.
