Neuroendocrine Tumours (NETs)
- Neuroendocrine tumours (NETs) are relatively rare cancers. They start in a person’s neuroendocrine cells, found throughout the body. NETs can be cancerous (malignant) or non-cancerous (benign). They often grow slowly, but not always.
- Different types of NETs are named based on the place in the body where they develop:
- NETs can develop in organs of the gastrointestinal (GI) tract, including small intestine, rectum and stomach, colon, esophagus and appendix. These types of tumours are called GI NETs.
- NETs can also develop in the lungs (called lung NETs) or the islet cells of the pancreas (called pancreatic NETs or pNETs).
- Other types of NETs include thyroid cancer, pheochromocytoma (adrenal gland) and Merkel cell carcinoma (skin).
