Mesothelioma Staging Systems
There are currently three main staging systems used by doctors to determine how far a patient’s mesothelioma has progressed.  Each system uses 4 stages to describe the progression of a particular case, but the definitions of the stages vary slightly according to the method used..



Butchart Staging System
The Butchart System is the most widely recognized and most commonly used 
mesothelioma staging system.  This system is based on tumor size, dividing malignant 
mesothelioma into four stages..
Who should be concerned?
Asbestos is imported into the United States and was even mined in the country during the 20th century. In the US, the use of asbestos peaked in 1973 when it amounted to 803,000 metric tons before declining to 1,700 metric tons in 2007. Industrial workers employed in settings such as manufacturing, construction and shipbuilding prior to 1980s are the ones who are at most risk, as federal safety regulation was not in place at the that time. Exposure continues to occur today because of the demolition of buildings in which asbestos was used during construction.
