Mesothelioma, a rare tumor, is highly correlated with asbestos exposure. 
Mesothelioma, similar to all asbestos-related diseases, is dose/intensity 
dependent to some degree, and studies showed the risk of mesothelioma rises with 
cumulative exposures. Multiple processes occur in an individual before 
mesothelioma occurs. The impact of mesothelioma in the United States has been 
continuous over the last half century, claiming between 2,000 and 3,000 lives 
each year. Mesothelioma is a preventable tumor that is more frequently reported 
as associated with asbestos exposure among men than women. However, the rate of 
asbestos-associated mesothelioma is on the rise among women due to better 
investigation into their histories of asbestos exposure. It is of interest that 
investigators detected asbestos-associated cases of mesothelioma in women from 
nonoccupational sources-that is, bystander, incidental, or take-home exposures. 
It is postulated that asbestos-associated mesotheliomas, in both men and women, 
are likely underreported. However, with the implementation of the most recent 
ICD-10 coding system, the correlation of mesothelioma with asbestos exposure is 
expected to rise to approximately 80% in the United States. This study examined 
the demographic and etiological nature of asbestos-related mesothelioma.
