Histamine - Ronny Allan - Living with Neuroendocrine Cancer

Tag: Histamine

A substance that has many effects in the body. It is released from some types of white blood cells during allergic reactions. It causes small blood vessels to dilate (widen) and become leaky, which can cause tissues to swell. It also causes smooth muscles to contract, gastric acid to be made, and the heart rate to increase. Histamine is used in tests for allergies, asthma, and gastric acid secretion. It also has an important role in the brain where it functions as a neurotransmitter.

Rosacea – the NET Effect

Awareness, Patient Advocacy

Around 2001, I started noticing some issues on my nose, particularly around the creases, an issue I still experience today. It normally starts with a stinging feeling, an indication I'm about to experience some sort of inflammation. What eventually happens is something which looks like a 'whitehead' which I now know to be a 'pustule'. Sometimes there are multiples, and most are not normally bigger than 2mm, mostly smaller. These pustules nearly always disappear within a short period of time, normally after washing/showering, but they tend to leave reddish marks which eventually fade. Very infrequently, these pustules would appear on my chin. My nose is slightly discoloured and more reddish than the rest of my face since the issue started. Shortly after I started experiencing this issue, a doctor diagnosed me…

Living with Neuroendocrine Cancer – the 7 Year Itch

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Treatment

Share on facebook Facebook Share on twitter Twitter Share on pinterest Pinterest Share on whatsapp WhatsApp Share on email Email I quite like the Facebook memory thing. This morning I got a reminder of a post I made from 7 years ago whilst I was in hospital recovering from my 9 Nov surgery. It had taken 12 days for me to feel strong enough to venture onto social media with a simple message "I'm feeling perkier". For those not familiar with English localisms, it just means lively, spirited, bright, sunny, cheerful, animated, upbeat, buoyant, bubbly, cheery, bouncy, genial, jaunty, chirpy, sprightly, vivacious, in fine fettle, full of beans, bright-eyed and bushy-tailed. I guess I met some of these descriptors most of the time! I had gotten through the worst and…

Neuroendocrine Cancer – tumour markers and hormone levels

Patient Advocacy

BackgroundI think most people 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 much higher levels in cancerous conditions. These substances can be found in the blood, urine, stool, tumour tissue,…

Serotonin – the NET effect

Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy

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…

Neuroendocrine Cancer Nutrition Series Part 4 – Amines: Food for Thought?

Diet and Nutrition, Living with Neuroendocrine Cancer, Patient Advocacy, Survivorship

reviewed and updated 12th Feb 2022Background.Nutrition is an important subject for many cancers, but it can be particularly important for many Neuroendocrine Cancer patients. When I started writing my nutrition series (I listed the other parts below), I said that my intention is not to tell you what to eat, even though that might be a challenge for many, and this theme continues. The issue with Nutrition and Diet, in general, is that it's very individual and what works for one may not work for another.I like to focus on why such things might have an effect - patients can then experiment and see what works for them. Sometimes very few changes are required and settling on a diet that works for you is the optimum solution. p.s. Not everyone has…

I bet my flush beats yours?

Awareness, Living with Neuroendocrine Cancer, Patient Advocacy, Treatment

BackgroundNeuroendocrine Tumours (NETs) can sometimes present with one or more vague symptoms which occasionally results in a lengthy diagnostic phase for some. Sure, there can be issues with doctor experience and knowledge that can add to the problem. However, some people do present with multiple vague and confusing symptoms and some people have comorbidities that have similar symptoms. Textbook diagnostics just don't make sense, sometimes even when the doctor suspects a NET i.e. classic symptoms of 'something' but with negative markers for NETs. Clearly, those are extreme cases and just like other complex diseases, many diagnoses of NET can be extremely challenging. Even for an experienced doctor, it can be a difficult jigsaw!Most types of NET can have associated 'syndrome' i.e. the tumours are 'functional' and this is normally (but not always)…

Neuroendocrine Cancer – Horrible Hormones

Patient Advocacy

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) is useful to aid a diagnosis, albeit…
