neuroendocrine tumor

Neuroendocrine tumors (NETs) are a diverse group of tumors that arise from neuroendocrine cells found throughout the body. These cells receive signals from the nervous system and can release hormones into the bloodstream. NETs most commonly occur in the digestive tract, pancreas, and lungs. Some neuroendocrine tumors produce excess hormones and cause specific symptoms, while others produce few or no hormone-related effects. NETs can range from slow-growing tumors to more aggressive cancers depending on their type, grade, and location. Examples include pancreatic neuroendocrine tumors, gastrinomas, insulinomas, and carcinoid tumors. Diagnosis and treatment depend on tumor characteristics and may involve imaging, laboratory tests, surgery, medications, or other therapies.

A neuroendocrine tumor is a tumor that starts from special cells that connect the nervous system and hormone system. Some release hormones that cause symptoms, while others may grow without producing noticeable hormone effects.

• Also called NET • Develops from neuroendocrine cells • Can occur in the digestive system, pancreas, lungs, and other organs • Some NETs release hormones and cause specific symptoms • Others may not produce hormone-related symptoms • Can be slow-growing or aggressive depending on type • Examples include gastrinoma and insulinoma • Treatment depends on location, growth rate, and spread
