Neuroendocrine Tumors | Symptoms & Causes

What are the symptoms of neuroendocrine tumors?

The symptoms of a neuroendocrine tumor  (NET) may vary from child to child and can depend on where the tumor is located, what kind of neuroendocrine tumor it is, and what type of hormone it secretes. Symptoms might mimic other, more common ailments.

Some of the most common symptoms may include:

  • abdominal pain that resembles appendicitis
  • high blood pressure, dizziness, heart palpitations, nausea, vomiting, or excessive
  • abdominal pain, stomach ulcers, vomiting, diarrhea, or weight changes
  • lump or swelling in the neck
  • pain or feeling full near the site of the tumor if the tumor is large

Because many of these symptoms can also point to other conditions, it’s important to have your child evaluated for diagnosis by a qualified medical professional right away.

What causes NETs? 

Some neuroendocrine tumors result from hereditary factors. Examples of hereditary or genetic conditions that carry an increased risk for developing NETs include multiple endocrine neoplasia (MEN), familial medullary thyroid cancer (FMTC) syndrome, von Hippel-Lindau syndrome, hereditary paraganglioma-pheochromocytoma syndromes, and Carney triad.
