Neuroendocrine tumours
The neuroendocrine system is a network of glands and nerve cells that make hormones and release them into the bloodstream. These hormones help control normal body functions, for example digesting food. Neuroendocrine cells are found throughout the body, but mainly in the gastro-intestinal tract (including large bowel and small bowel), pancreas and lungs. Neuroendocrine tumours (also referred to as NET) are an uncommon type of tumour that forms in these cells.
