What are the stages of mesothelioma?
In stage I, the cancer is localized in the chest wall lining, lung lining, diaphragm lining or the lining of the sac covering the heart. In stage II, the cancer has spread to the lymph nodes. In stage III, the cancer has spread to the chest wall, the mediastinum, the heart, beyond the diaphragm, the peritoneum and/or the lymph nodes. In stage IV, the cancer has spread to distant organs or tissues.
