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 has certain unique features whereby tumours can produce one or more symptoms which are known collectively as a syndrome.  Neuroendocrine Tumours secreting excess amounts of serotonin, can be accompanied by Carcinoid Syndrome which if not diagnosed and treated early enough, can lead to an additional complication known as Hedlinger Syndrome (often known as Carcinoid Heart Disease (CHD)). However, very late diagnoses can present with CHD already in place. Excess serotonin, a hormone released by NETs into the bloodstream seems to be the prime and lead suspect for causing thick ‘plaques’ or fibrosis tissue within the heart muscle and damage to (mainly) the tricuspid and pulmonary valves on the right side of the heart which can become ‘tightly narrowed’ or ‘leaky’.  It's very similar to the reasons for mesenteric and peritoneal…
