How much exposure to asbestos is needed for there to be a possibility of getting pericardial mesothelioma?
This depends on how strong and resistant the person is to disease and on the concentration of asbestos in the environment around him. It is possible to get pericardial mesothelioma from as little as a couple of months of exposure to asbestos although on average it would take a couple of years for enough asbestos fibres to build up to cause cancer.
