Though researchers continue to develop new ways to diagnose and treat mesothelioma, there are a number of techniques that have been on the scene for several decades. One such technique, thoracentesis, was developed in the late 19th century and is still used today.
Thoracentesis, the extraction of fluid from the lungs and the pleura (pleural effusion), can be used for two purposes. The first is as a diagnostic tool. In this procedure, a doctor uses a hollow needle, or cannula, to extract pleural fluid. This procedure helps to determine the causes behind the fluid buildup. The fluid is then examined for certain qualities that may indicate disease. Usually, however, thoracentesis is not sufficient to determine whether or not a person has mesothelioma. A biopsy is typically required as well.
