Neuroendocrine tumors are a rare type of tumor affecting specialized neuroendocrine cells. Neuroendocrine cells are cells similar to nerve and hormone-producing cells. These tumors can be benigh (harmless) or malignant (cancerous). Cancerous neuroendocrine tumors can occur anywhere in the body and can spread slowly or quickly throughout the body, though most grow over the course of years. People with Multiple Endocrine Neoplasia type 1 or 2, Von Hippel-Lindau disease, Tuberous sclerosis, and Neurofibromatosis are more at risk for neuroendocrine cancer. Sometimes this cancer will affect your hormone production and can cause behavioral changes.
Treatment for neuroendocrine tumors depends on the type and mass of the tumor, and ranges from chemotherapy to radiation to surgery.
