Mesothelioma treatment options (traditional and new treatments being studied)

Treatment options are determined by the stage of mesothelioma (the extent to which the tumor has spread in the body). There are three staging systems currently in use, and each one measures somewhat different variables.

The oldest staging system and the one most often used is the Butchart system, which is based mainly on the extent of primary tumor mass and divides mesotheliomas into four stages.
