Tag: Neurotransmitter

A chemical that is made by nerve cells and used to communicate with other cells, including other nerve cells and muscle cells. Experts have identified more than 100 neurotransmitters to date. Neurotransmitters have different types of action:

Excitatory neurotransmitters encourage a target cell to take action.
Inhibitory neurotransmitters decrease the chances of the target cell taking action. In some cases, these neurotransmitters have a relaxation-like effect.
Modulatory neurotransmitters can send messages to many neurons at the same time. They also communicate with other neurotransmitters.

The key ones are Serotonin, Dopamine, Acetylcholine, Endorphins, Adrenaline (Epinephrine), Gamma-aminobutyric acid (GABA),

Neuroendocrine Cancer – Horrible Hormones

Patient Advocacy

Updated and reviewed 20th March 2024 Hormonal imbalances are quite common in many conditions including day to day stuff. With Neuroendocrine Cancer, it can be a real challenge both at diagnostic and maintenance phases. In addition to the cancer angle, there's some strange stuff going on, inexplicable, frightening for the patient, an unwanted ingredient causing chaos! Until I was diagnosed with metastatic Neuroendocrine Cancer, I didn't have a clue about hormones - it's one of those things you just take for granted. However, hormones are vital to human health (male and female) and it's only when things go wrong you suddenly appreciate how important they are. Hormones are involved in many conditions, not just an issue with Neuroendocrine Tumours (NETs) but the presence of over-secreting hormones (often called peptides throughout)…

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 […]
