X-Rays, CT scans. MRI and PET scans provide a fair diagnosis. However, to reach a definitive conclusion a physician often recommends a biopsy. A biopsy is a surgical procedure in which a tissue sample or receive fluid from the affected area and it is then examined in a laboratory by a pathologist. The sample is then analyzed under a microscope and a final conclusion can be reached, whether the individual has Mesothelioma or not. A biopsy can also determine theCells of the type of mesothelioma, so that the appropriate treatment plan can be established. The physician selects the appropriate biopsy, depending on the area affected.
If the patient accumulation of fluid in the chest (pleural effusion), has a long hollow needle can be inserted into the thoracic cavity and a sample of this fluid is aspirated. The same procedure can be done if the patient has fluid in the abdominal cavity or around the heart. This liquid is thenanalyzed in the laboratory to determine whether cancer cells are present. If this is the case, further tests must be conducted to determine whether the cancer mesothelioma or some other type of cancer. However, this procedure leads often inconclusive results, and many doctors want to take a tissue sample.
To take a biopsy, a needle is inserted into the chest and then rotated. Tissue samples will be when the needle is removed collected.However, these methods are can be dangerous, because there the chance of tumor seeding along the needle tract, radiotherapy may be so, according to which the test is performed. Because the fabric is usually made is small, this method has limited reliability.
A tissue sample can be achieved by a new technique called thoroscopy. In this method, a thoroscope (like a telescopic instrument to a video camera attached) is inserted through a small incision in the chest of the patient. The doctors can seethe tumor through the thoroscope. With the help of special forecep a sample of the tumor can be removed. This technique is usually performed under local anesthesia and is usually performed in cases of pleural mesothelioma and pericardial mesothelioma.
In the case of peritoneal mesothelioma, a laparoscopy is performed to obtain a sample of the tumor. A laparoscopy is similar thoroscopy but the procedure is performed in the abdominal cavity instead ofthe breast. At laparoscopy a hose attached to a video camera is introduced into the abdomen through a small incision. The physician can then take the body of the patient's appearance and the samples of altered tissue. This procedure is usually performed under general anesthesia and more than one cut can be performed. Fluid samples may be taken during the laparoscopy and thoroscopy.
Thoracotomy is a surgical procedure to open the chest and check for signs of tumors. A largeTissue sample is taken to be tested in the laboratory. Sometimes the tumor is removed during this procedure.
Laparotomy is surgery in the abdominal cavity to open and check for signs of tumors. A large tissue sample is taken in order to be tested in the laboratory. Sometimes the tumor is removed during this procedure.
VATS (Video Assisted Thoracoscopic Surgery) is a procedure done in which several small incisions in the chest wall. A camera and the necessary surgicalInstruments can be used in various sections in order to collect tissue samples. The surgeon can look at a screen showing the images of the camera.
Mediastinoscopy is a procedure done in which a small incision above the sternum and inserted a tube in his chest and moved down. A doctor can look at the lymph nodes through the tube. Lymph nodes are part of the immune system of the body and their function is to collect and destroy bacteria and viruses. When the body is fightingan infection or cancer, are usually swollen lymph nodes. With a view to obtain the lymph nodes, the doctor information about the nature and spread of cancer. Obtained by analyzing the tissue samples, the pathologist can determine whether the tumor is mesothelioma or some other type of cancer.
Peritoneoscopy is a procedure that, in case of peritoneal mesothelioma can be carried out if the doctor can look inside the abdomen through an incision with a peritonescopeMade in the stomach. If fluid is removed first in the abdominal cavity is collected.
Bronchoscopy is a procedure that will be used if the patient is suspected to be, may have pleural mesothelioma. Introduced a flexible tube (bronchoscope) into the bronchial tubes through the mouth of the patient to see a mass in the airways. The doctor can see into the airways through an eyepiece. The doctor may abnormal-looking samples of tissue for analysis.
