Welcome to my Neuroendocrine Cancer terms and definitions list providing a source of meanings for acronyms and medical terms, all sourced from top cancer/Neuroendocrine Cancer sites. This version is a simple combination of an intelligent search (e.g. type first character to filter etc) plus a simple long list of all the terms in my repository. But each has a link which will direct you to the definition of the term plus where applicable, links to any of my articles where I have tagged this term (therefore providing added context).Please note I’m constantly working on the repository to clean up all definitions, adding…

Neuroendocrine Cancer: Functional vs Non-functional

A spotlight on NENs - Syndromes, Patient Advocacy, Spotlight on NENs - Types SeriesCarcinoid syndrome, Cushing's syndrome, Ectopic Cushing’s syndrome (ECS), Functional tumour, Gastrinoma, Glucagonoma, Insulinoma, NET syndromes, Non-functional tumour, Somatostatinoma, VIPoma

The terms functional and non-functional come up a lot in documents describing Neuroendocrine Cancer. They also feature highly in patient groups. But what do these terms actually mean? Functional / Non-FunctionalNeuroendocrine Tumours are treatable for most but the difficult part can be arriving at a diagnosis. Moreover, some Neuroendocrine Tumours (NETs) can be silently growing and as they grow slowly, the 'silence' can go on for some years. Even with a syndrome, the root cause can remain disguised as the symptoms are similar to many day-to-day illnesses. There can be the odd exception but in general terms, NETs are either functional (with…

A spotlight on Appendiceal Neuroendocrine Neoplasms

A spotlight on NENs - Types, Awareness, Patient Advocacy, Spotlight on NENs - Types SeriesAppendectomy, Appendiceal NET, Appendix, Right hemicolectomy

What are Appendiceal NENs Appendiceal Neuroendocrine Neoplasms (NENs) account for approximately 60% of all primary cancers in the appendix. The other main cancer types found in the appendix are regular adenocarcinomas (including signet ring cell and goblet cell) and mucinous neoplasms such as Pseudomyxoma Peritonei (PMP) or Low-Grade Mucinous Neoplasms (LAMD). Appendiceal neuroendocrine tumours (aNET) (i.e. well differentiated) account for 75% of all aNENs, are mostly indolent tumours treated effectively with simple appendectomy. In fact, most are incidentally found upon presentation of right lower quadrant (RLQ) pain in keeping with appendicitis. They are typically (but not exclusively) diagnosed in younger…

A spotlight on Gastric Neuroendocrine Neoplasms (based on 2026 WHO Classification)

A spotlight on NENs - Types, Awareness, Patient Advocacy, Spotlight on NENs - Types Series, TreatmentAtrophic gastritis, Gastric NET, Gastrin, Gastrin pH, Gastrinoma, Hypergastrinemia, Neuroendocrine carcinoma (NEC), Neuroendocrine neoplasm (NEN), Neuroendocrine tumour (NET), Pernicious anaemia, Proton pump inhibitors (PPI)

What are Gastric NENs Unlike other anatomical types, the word Gastric is used to indicate a tumour (NET) or carcinoma (NEC) in the stomach. The stomach lies at the bottom of your oesophagus and connects to the first part of the small intestine (the duodenum). Clearly a key part of the gastrointestinal system, it processes food on its journey downwards. The stomach produces strong acid. This kills many microorganisms that might have been swallowed along with the food. It also contains special chemicals called enzymes. These are important for breaking down the food so it can be absorbed by the…

A Spotlight on Lung Neuroendocrine Neoplasms

A spotlight on NENs - Types, Awareness, Patient Advocacy, Spotlight on NENs - Types SeriesAtypical carcinoid tumour, Atypical Lung NET, Combined Neuroendocrine Carcinoma, Cushing's syndrome, DIPNECH, Large cell neuroendocrine carcinoma (LCNEC), Lung NETs, MEN1 syndrome, Neuroendocrine carcinoma (NEC), Small cell lung cancer (SCLC), Syndrome of inappropriate antidiuretic hormone secretion (SIADH), Typical lung NET

WHO Classification of Tumours, 5th Edition, Volume 5: Thoracic Tumours The aim of this spotlight is to provide a summary of the latest information on Lung Neuroendocrine Neoplasms (NEN) including the latest terminology, epidemiology data, and guidelines. This follows the publication of the Thoracic WHO classification 5th edition (2021): terminology and criteria for neuroendocrine neoplasms (Blue Book). This book has been anticipated to see if the panel compiling this follows the lead of the Gastroenteropancreatic Neuroendocrine Neoplasms (GEPNEN) editions issued in 2017 (Endocrine) and 2019 (Digestive systems) by removing the antiquated misnomer term ''Carcinoid" in line with the recommendations made…

Updated 19th August 2025 I spend a lot of time talking about the most common forms of Neuroendocrine Tumours (NETs), but what about the less well-known types? As part of my commitment to all types of NETs, I'd like to shine a light on two less common tumour types known as Pheochromocytomas and Paragangliomas - with an incidence rate of approximately 8 per million per year. They are normally grouped together, and the definitions below will confirm why. If you think it's difficult to diagnose a mainstream NET, this particular sub-type is a real challenge. So, let's get definitions out…
