The serotonin test measures the level of serotonin in the blood. It can be used in conjunction with the more stable test of 5HIAA (a serotonin metabolite.

Neuroendocrine Cancer – tumour markers and hormone levels

A Spotlight on NENs - Testing Series, Patient Advocacy

BackgroundSome people on hear the terms "tumour markers" and "hormone levels" when they are diagnosed with Neuroendocrine Cancer. Most of them will have had a form of medical testing at some point in their life, i.e. the sampling and testing of blood, urine, saliva, stool or body tissue. In a nutshell, the medical staff are just measuring the content of a 'substance' and then taking a view whether this is normal or not based on pre-determined ranges. These tests are normally done as a physician's reaction to symptom presentation or maintenance/surveillance of an existing diagnosed condition. Sometimes, abnormal results will lead to more specialist tests.In cancer, these tests are frequently called 'markers'. Most tumour markers are made by normal cells as well as by cancer cells; however, they are produced at…

Serotonin – the NET effect

Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, The NET Effect Series

picture shows an actual serotonin receptor BackgroundI'd never heard of Serotonin until I was diagnosed with Neuroendocrine Cancer in 2010. It is frequently discussed, often with contrasting views from the respondents. One common assumption/question is that it is responsible for many things that can go wrong with Neuroendocrine Cancer patients who have serotonin-producing tumours. To a certain extent, that's true but statement such as "it's the hormones" is an easy assumption to make; or an easy answer to give in response to a complex set of circumstances. It's difficult to get a definitive answer and the science behind the behaviour of our hormones isn't really 100% tied down - the human body is extremely complex.You may see serotonin referred to as a 'neurotransmitter', a 'chemical' and a 'hormone' - this…

Update of one of my posts from 2015 which was interesting in that year. This is not really about a treatment which is available everywhere but was a novel approach by one of the world’s most gifted and innovative NET surgeons. Please note this is not a nutrition post! One of my daily alerts brought […]

“An odd disposition of tumours” – less common metastases in Small Intestine and Pancreatic NETs

Every day is a learning day in NET! When I was diagnosed in 2010, my Oncologist sent me for a specialist scan that would help confirm my staging definition and to document anything that might not have shown up on CT. This was described as an Octreotide Scan (somatostatin receptor scintigraphy) (now mostly replaced by […]

Chemotherapy for Neuroendocrine Cancer

Edited and checked April 2024 One of the unusual aspects of Neuroendocrine Cancer is that chemotherapy is not normally considered as a ‘standard of care’ or first-line treatment, unlike many other cancers. One exception is high grade (Grade 3) where it is very often a first and/or second-line therapy. This is particularly the case with […]

Carcinoid vs Neuroendocrine

OPINION – There’s a constant debate regarding the validity of the term ‘Carcinoid‘. I’ve posted about this a few times and as far as I know, the debate has been raging for some years. This post was originally generated in April 2015 (and hasn’t changed that much!). EDIT MARCH 2024. There is now a consolidated Endocrine/Neuroendoceine […]

Things are not always how they seem

Graphic courtesy of SoBadAss.me (Sam Cleasby) In 2014, Chris and I walked 84 miles along Hadrian’s Wall on the English/Scottish border. It was a fantastic experience, and we met some really interesting people on our 6-day journey. On the 4th night, I encountered a lady who was pretty rude. I wanted to say something, but I […]
