Internal radiation therapy, by contrast

Clinical research to treat malignant mesothelioma is very active and although no treatment has yet proved entirely successful, there exist a range of treatments available to individuals diagnosed with the disease. There are three types of standard treatments used to treat malignant mesothelioma which include: surgery, radiation therapy, and chemotherapy. Surgery Surgery for malignant mesothelioma is divided into a number of sub-classes, which are specially designed to limit the disease for individuals with particular strains of the disease. Extrapleural pneumonectomy is a severe form of surgery in which the entire lung and a portion of the lining of the chest, the diaphragm, and some or the entire sac which surrounds the heart is removed. Wide local excision is a form of surgery which targets and removes the cancer and a limited amount of the healthy tissue surrounding the cancerous region. Pleurectomy and decortication removes part of the covering of the lungs, as well as the lining of the chest and portions of the outside covering of the lungs. The surgical procedure pleurodesis is a distinct technique insofar as it employs a blend of chemicals and/or drugs to create an intentional scar between the layers of the pleura. Post surgery, the space created by the scar must be drained, using either a catheter or chest tube, and is then filled with a chemical which inhibits the accumulation of fluid in the pleura cavity.
