Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

What are carcinoid tumors / syndrome?

What are carcinoid tumors / syndrome?

Neuroendocrine tumor: 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

What's the safest way to treat carcinoid tumors?

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

What are the symptoms of carcinoid tumors I should be looking for?

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

Medications that can decrease 5-hiaa include aspirin, ethyl alcohol, imipramine, levodopa, heparin, isoniazid, methyldopa, and tca's.

Are the symptoms of carcinoid tumors bad?

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

Can you tell me the life expectancy ranges based on for carcinoid tumors?

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

Who is most prone to getting carcinoid tumors/syndrome?

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 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

Carcinoid (Definition)

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
