A mesothelioma, in general, is an aggressive malignant tumor, the vast majority arising from the pleural.

It is strongly associated with asbestos exposure, therefore afflicting those in industries with potential exposure, such as electricians and shipbuilders.  A significant lag response is known, being up to 20-30 afters exposure.

It typically causes circumferential thickening of the pleura, encasing the lung with resultant volume loss.

Treatment options are limited.  Prognosis is poor.
