Mesothelioma Stages - Stage I
Stage I mesothelioma is the easiest to treat, as the disease remains localized in the pleura and has not yet spread elsewhere. Such mesothelioma treatments as surgery are more likely to be used in Stage I cancers than in more advanced stages that involve multiple tumors in different locations.
Treatment options are often determined by your stage of mesothelioma. The staging systems used for mesothelioma apply only to pleural mesothelioma, though any form of the disease will be evaluated using similar criteria to determine its extent and progress.

The three staging systems that doctors use to assess mesothelioma are the Butchart, TNM and Brigham systems. Though all three overlap to some degree as indicated below, each system has its particular utility and applications.
Stage I, Butchart system: Mesothelioma is located in the pleura on either the right or left side, not both. It may also be found in the lining of the chest cavity between the lungs and/or the lining that covers the diaphragm. The lymph nodes remain unaffected.
Stage I, TNM system: Cancer is found in either the right or left pleura and has only spread to the outer lining of the lung in, at most, a few small spots. The lymph nodes remain unaffected.
Stage I, Brigham system: Mesothelioma is operable and the tumor(s) can be removed. The lymph nodes remain unaffected.
