Mesothelioma diagnosis

Mesothelioma diagnosis is often difficult because symptoms are similar to many other conditions. Beginning with the diagnosis of the patient medical history. A history of exposure to asbestos may increase clinical suspicion for mesothelioma. Physical examination performed, followed by chest X-ray examinations and lung function often. May X-Ray revealed pleural thickening commonly seen after asbestos exposure and increases suspicion of mesothelioma. A CT (or CAT) scan or MRI is usually done. If there is a large amount of fluid, abnormal cells can be detected by liquid cytology if it is aspirated with a syringe. For pleural fluid this is done by pleural tap or end of the chest, in ascites with paracentesis or ascitic East and in pericardial fluid by pericardiocentesis. Despite the absence of malignant cells on cytology does not completely exclude mesothelioma, it will be more, especially if an alternative diagnosis can be made (eg tuberculosis, heart).
If cytology is positive or plate is considered suspect, A biopsy is needed to confirm the diagnosis of mesothelioma. Doctor remove the network as an example of the microscopic pathology. A biopsy can be done in different ways, depending on where the abnormal area is located. If the cancer in the chest, the doctor may perform thoracoscopy. Under this procedure, doctors make a small cut through the chest wall and put small, lighted tube called a thoracoscope to the chest between two ribs. Thoracoscopy allows the doctor to see the chest and the example network.
If the stomach cancer, doctors may perform laparoscopy. To get the network to review, the doctor makes a small incision in the stomach and enter a special instrument into the abdominal cavity. If this procedure does not produce enough network diagnostic surgery may be needed more widely.
