This process is often difficult, because the indications are similar to a number of other conditions. Biopsy comprises of physical tests, chest X-ray, lungs function test, laparoscopy, breast cancer test and more.The history of exposure to asbestos may also enhance medical doubts for Mesothelioma.

Therefore a physical examination is performed, followed by chest X-ray and often lung function tests. The X-ray may disclose pleural thickening commonly seen after asbestos exposure and increases doubt of Mesothelioma Cancer. A C.T. scan or an MRI is generally done. If the liquid is in huge quantity, abnormal cells may be detected by cytology if this fluid is aspirated with an injection. Pleural tap or chest drain is used for pleural fluid, in ascites with paracentesis or ascitic drain and in a pericardial effusion with pericardiocentesis.

Mesothelioma Diagnosis

If cytology is positive or a plaque is regarded as doubtful, a test is needed to confirm or diagnose Mesothelioma. Doctors take a sample of tissue for examination under a microscope by a histopathologist. A biopsy may be done in different ways, depending on where the abnormal area is located. If the cancer is in the chest, the doctor may perform a thoracoscopy. In this procedure, the doctor makes a small cut through the chest wall and puts a thin, lighted tube called a thoracoscope into the chest between two ribs. Thoracoscopy allows the doctor to look inside the chest and obtain tissue samples.

If abdominal cancer is proved by cancer diagnosis, the doctor may perform a laparoscopy. To obtain tissue for examination, a small opening is made in the abdomen and a special instrument is inserted into the abdominal cavity. If these actions do not yield enough tissue, more wide diagnostic surgery may be required.
