They originate from different types hormone-producing cells located not only in endocrine glands like the thyroid but almost every tissue. Even when NET can arise part body, lung (about 30 % all NETs) and gastroenteropancreatic system – so-called GEP (small intestine 17 %, colorectal 12 pancreatic 7 %) most common locations Especially, GEP-NETs often diagnosed at already advanced tumor stage (UICC IV) exhibiting liver metastases.
