Are Carcinoid Tumors Linked To Asbestos
Carcinoid refers to neuroendocrine tumors originating in gastrointestinal (GI) tract, lungs and appendix. They are usually indolent developing over many years. Aggressive, fast-growing forms such SCLC known as Oat Cell Ca of lung represents neuroendocrine carcinoma that exhibits rapid growth and early spread to distant sites. They are sensitive ...Read more
It is a relatively benign type of tumor that can secrete a variety of hormones, most notably serotonin. They are most commonly found in the gut or the lungs. They do not come from the lining of the lungs or the gut (as adenocarcinomata do). They come from a different line of cells.
Carcinoid syndrome occurs when large amounts of serotonin get into the bloodstream, assoc with flushing and diarrhea. ...Read more
Location? Extent?: Tumors of neuroendocrine origin; can be hard to localize; can be in appendix, rectum, bowel, stomach/duodenum, ovaries, bronchi (breathing tubes), elsewhere. "low" malignant potential, but can be aggressive, spread; can cause abd pain, ;"syndrome" with flushing, wheezing, murmurs, etc. Small ones can be cured by surgical removal; may need chemo, embolization, or octreotide rx for symptom control. ...Read more
Carcinoid tumor: Carcinoid tumors can be found in several places in the intestines. They do not cause symptoms unless the liver is affected. Carcinoid syndrome can be associated with flushing, increase in blood pressure, irregular heart beat, etc. If a carcinoid is located with a bowel lumen it can cause blockage. Carcinoids can spread directly to other areas. Usually not by blood stream. ...Read more
Long yet variable: Carcinoid tumors are slow growing cancers which can exist in the body for 10-20+ years without causing a major threat to life. But this depends on where they are located and if they have spread to the liver or not. Liver spread does lead to increasing problems and some fatal outcomes, typically after 5 to 10+ years. It has a highly variable prognosis. ...Read more
Not always!: The most common place to have a carcinoid is the appendix. When the tumor is there, and most of the other common locations which are in the intestinal tract, you don't feel anything because the liver removes the hormones the tumors produce. Only when the tumors are large, outside the intestinal tract, or metastatic do the symptoms occur. They can get very bad then. ...Read more
Not known: Carcinoid tumors of the bowel are neuroendocrine tumors that have a high propensity of spreading to the liver and producing the carcinoid syndrome. The lesions arise anywhere in the bowel and respond to the same chemo used for small cell neuroendocrine of lung. They even arise in organs like pancreas, like Jobs had but are not pancreatic tumors. Cause is not known but possibly viral in etiology ...Read more

Can Abilify (aripiprazole) cause false negative test results when being tested for carcinoid tumors?
There are a variety of drugs that can affect the 5-hiaa test. Medications that can increase 5-hiaa include acetaminophen (in percocet) ephedrine, (ephedrine sulfate) diazepam (valium), nicotine, , and phenobarbital. Medications that can decrease 5-hiaa include aspirin, ethyl alcohol, imipramine, levodopa, heparin, isoniazid, methyldopa, and tca's.

Octreoscan is used for visualization of carcinoid tumors based on SOM receptor ability to bind octreioide analogs. Does the same apply for mast cells?
Unlikely: There is no evidence that octreotide scans are able to image mast cells. ...Read more
Mother was diagnosed with carcinoid cancer can that put me at a higher risk to develope carcinoid tumors?
No: Those is no inherited predisposition to these tumors. ...Read more
What is the risk of having multifocal carcinoid tumors in stomach and duodenal type-1 and what is the latest news about available treatments?
REcurrence: Type I gastric carcinoids are the most common and usually do not metastasize. They require careful surveillance with endoscopic resection for the smaller lesions and antrectomy for multifocal and larger recurrences. Reduction of gastrin levels felt to be helpful. ...Read more
Does carcinoid syndrome/ carcinoid tumors always present with frequent diarrhea and constipation?
Are carcinoid tumors carcinoma? Is malignant metastatic stomach carcinoma that's hereditary a carcinoid cancer? Carcinoid Neuroendocrine tumors?
Can carcinoid tumors cause carcinoid crises with clonoscopy&endoscopy anesthesia? I have elavated serotonin;constipation, heat in neck&head;night diahri
Unlikely: Carcinoid crisis is a possible complication in someone who has a carcinoid tumor. You don't say if you have been diagnosed with Carcinoid. General anesthesia can trigger carcinoid crisis in such patients, but the "conscious sedation" used for most diagnostic procedures such as colonoscopy or endoscopy would be unlikely to do so. Have you done a 24 hr urine 5-HIAA? ...Read more
Slower growing: Carcinoid tumors can occur throughout the intestine and may act in a malignant fashion and spread to lymph nodes and other organs. They tend to grow more slowly that more common (adenocarcinomas) cancers in the intestinal tract. They can sometimes be cured with surgery and survival can be long term even after spread due to their nature of sometimes growing very slowly. ...Read more
Asbestos is a silicate mineral that was used extensively in construction as insulation for buildings. It was later found to cause lung disease in humans, and is no longer used in construction. However, the demolition of old building continues to put some people at risk of ...Read more
