Most carcinoid tumors grow in the gastrointestinal tract, including the small intestine, appendix, colon and rectum, stomach and pancreas.
They account for about 1/3 of all tumors of the small intestine, of which 50% are malignant.However, despite this and carcinoids can be detected in the lungs, ovaries or any other organs.
Carcinoid tumors are neuroendocrine.This means that they originate from the cells of the nervous and endocrine systems, and may form hormones and other biologically active substances.When tumor
generates substances such as histamine and serotonin, that gives rise to the so-called carcinoid syndrome.It is characterized by a rush of blood to the skin, stomach cramps and diarrhea.
Like most other types of cancer, carcinoid easiest to treat when detected early.In the early stages of these tumors can be
Symptoms of carcinoid tumor often blurry and vague, and are similar to symptoms of many other diseases.In some tumors of the gastrointestinal tract appear such symptoms as abdominal pain or cramps, constipation, bleeding.
carcinoids lungs may lead to the development of respiratory tract infections, pneumonia, chronic cough.
addition, carcinoid tumors may occur two states: carcinoid syndrome and Cushing's syndrome.
The symptoms of carcinoid syndrome include diarrhea, rush of blood to the skin, breathing with wheezing, shortness of breath, abdominal cramps and a feeling of palpitations.When Cushing's syndrome there is weight gain, muscle weakness, thinning of the skin, increased hair growth on the face and body (including women), increased blood sugar levels and high blood pressure.
According to Professor Richard Warner, head for the treatment of carcinoid tumors Foundation (New York, USA), many doctors often do not even think about these tumors.And this is the biggest problem in the diagnosis of carcinoids.Since they are relatively rare, experts simply do not compare the symptoms and possible causes.
Researchers still have not figured out definitively what causes these tumors.However, some risk factors are known precisely, and people are not able to control or change them.
Due to the slow growth of tumors are often detected data to metastasis, and often - and to the development of any symptoms.In many cases they are found during a routine inspection or examination for other diseases.
By its symptoms carcinoids rarely found.If the doctor suspects a carcinoid tumor, it may assign the following survey.
earlier carcinoid detected before it spread to other organs, the higher the chances of a complete cure by surgery.If the tumor has moved beyond its initial position, it may require combination therapy.In this surgical treatment is combined with chemotherapy, radiotherapy or radio frequency ablation, that is, the destruction of the tumor by means of high frequency pulses.
No matter how early the tumor is detected.Most importantly, how quickly treatment is started.Many doctors believe that it is better to wait until there are clear symptoms of the disease.However, it is the wrong tactic.Early aggressive treatment carcinoids provides the best prognosis for the patient's life.
