For those of you who are not familiar with mesothelioma, it’s a rare cancer that is associated with exposure to asbestos. At least that was what I always thought, but today I was visiting a site that had a lot more information about mesothelioma that states that malignant mesothelioma can occur in the absence of any known asbestos exposure which was determined because of the fact that in almost one third of the cases of people with this disease no exposure to asbestos was ever recorded.

Just goes to show that it is impossible to know everything about any given subject.
