Can You Carcinoid Tumors Quickly
How much metastasis does there need to be to cause carcinoid syndrome from midgut carcinoid tumors?
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
Highly variable: Some are very slow like meningiomas in the elderly, some very rapid, such as secondary metastatic spread from a primary source. Tumors in children tend to be localized in the mid-line posterior, and can rapidly create havoc due to location. Primary brain gliomas can start off seemingly localized and benign but can transform into horrendous glioblastoma multiforme. ...Read moreSee 1 more doctor answer
Depends on location: Serious symptoms from a brain tumor depend upon the location in the brain and the rate of tumor growth. There are parts of the brain where a tumor can grow to a large size with few symptoms and others where a small tumor can cause profound symptoms. ...Read moreSee 1 more doctor answer

Come again?: Your question is really WAY out there. I can't recall ever being asked that. I think some years ago there were studies that SUGGESTED that SSRIs MAY inhibit a metabolic pathway that THEORETICALLY could increase the risk, but they were on cell cultures, not on humans or even animals. Bupropion IS contraindicated to treat people WITH brain cancer. Maybe you heard that and got it backwards? ...Read moreSee 1 more doctor answer
Additional oncogenes: Many tumors begin as benign, eventually transforming to malignancy. Small lipomas as they grow develop additional oncogene mutations to become liposarcomas. Adenomatous polyps that are benign can have Cmyc and p53 nutations leading to malignant polyps. Additionally telometrase activity has to be put in place for immortality probably thru EBV transfection. ...Read more
Clinicopath. correla: One of the most important clinical features is the age of the patient. Approximately one of eight ovarian tumors in patients less than 45 year of age is malignant; by contrast, in older women, the proportion is about one of three. The single most common ovarian tumor, the mature cystic teratoma, dermoid cyst-benign tumor, is encountered at all ages. Clinicopathologic correlation is important. ...Read more
It is a fast growing: The exact starting time of any cancer is difficult to pin point. Most scientists believe that it can take more than one or two years(or perhaps upto 5/10 years) but the obvious visible tumors can show up in 6 to 12 months if you are undergoing regular medical check ups ...Read more
Yep! They can!: Benign neoplasms are non-cancerous growths. They can show up anywhere, kind of like moles. We tend to get more of them as we age. Usually they don't cause problems, unless they are big and pressing on something important (like your brain). It's a fancy word for a lump or bump that's not cancer. ...Read more
It Can Be Fast: 60-80% of vipomas are malignant and have metastasized by the time of diagnosis. Diagnosis usually takes years because of the insidious onset. They are also associated with men-1 (multiple endocrine neoplasm) syndrome, which is associated with other cancers of the pituitary and parathyroid glands. ...Read moreSee 1 more doctor answer
Absolutely yes: In many ways- obstruction to the adjacent organ from the increase size of the cancer; organ failure from cancer infiltration/replacement to the organ, decrease immune system and increase catabolism- cause weight lost and increase susceptibility to infections, erosion/invasion to blood vessel/organ cause bleeding, perforation, obstruction etc. Ultimately it can cause death. ...Read moreSee 2 more doctor answers
Size and feature: Tumors > 6 CM are high risk for malignancy. Tumors 4-6 CM are in the gray zone (you need to look at other fearues as well). Tumors < 4 CM are less likely to be malignant. There are features on the imaging studies that can also help your physcian determine the likelihood of tumor malignancy potential (hounsfield units, contrast wash out...). ...Read moreSee 2 more doctor answers
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
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
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 moreSee 2 more doctor answers
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

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 moreSee 1 more doctor answer
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
Can Abilify (aripiprazole) cause false negative test results when being tested for carcinoid tumors?
Apparently not: 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.

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 moreSee 1 more doctor answer
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 moreSee 2 more doctor answers
