Neuroendocrine Cancer – tumour markers and hormone levels

I 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…

Neuroendocrine Cancer – the diarrhea jigsaw

Diarrhea can be a symptom of many conditions but it is particularly key in Neuroendocrine Tumour (NET) Syndromes and types, in particular, Carcinoid Syndrome but also in those associated with various other NET types such as VIPoma, PPoma, Gastrinoma, Somatostatinoma, Medullary Thyroid Carcinoma. Secondly, it can be a key consequence (side effect) of the treatment for Neuroendocrine Tumours and Carcinomas, in particular following surgery where various bits of the gastrointestinal tract are excised to remove and/or debulk tumour load. There are other reasons that might be causing or contributing, including (but not limited to) endocrine problems such as hyperthryoidism, mastocytosis or Addison's disease (which may be secondary illnesses in those with NETs).  It's also possible that 'non-sydromic' issues such as stress and diet are contributing. It could be caused by other things such as Irritable Bowel…

Neuroendocrine Cancer Syndromes – Early Signs of a Late Diagnosis

Neuroendocrine Cancer Syndromes – Early Signs of a Late Diagnosis

Awareness, Diet and Nutrition, Living with Neuroendocrine Cancer, Technical NETs, Treatment
One of the curious things about Neuroendocrine Cancer (NETs going forward) is that it can very often exhibit one or more vague symptoms collectively known as a 'syndrome'.  Syndrome is an apt word to describe these complications as the most general meaning in medical terms is a group of symptoms that together are characteristic of a specific disorder or disease".  Having a syndrome can often be the difference between having a 'functional' condition or a non-functional' condition - see more below. This frequently makes Neuroendocrine Cancer very difficult to diagnose quickly.  It's a very devious disease. It's not all about Carcinoid Syndrome! Most people think of Carcinoid Syndrome when they discuss NETs. Anyone suggesting that all NET patients get carcinoid syndrome or that all symptoms of NETs are caused by carcinoid syndrome,…

Neuroendocrine Cancer – Hormones

Neuroendocrine Cancer – Hormones

Awareness, Living with Neuroendocrine Cancer, Technical NETs
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 ........like a lot of other things in life I suppose! The presence of over-secreting hormones (often called peptides throughout) is useful to aid diagnosis albeit it often (but not always) means the tumours have metastasized. It's also a frequent indication that the person has an associated NET syndrome. This is a really complex area and to understand the hormone problems associated with Neuroendocrine Cancer, you need to have a basic knowledge of the endocrine and neuroendocrine systems.  I've no intention…
