Direct breathing of asbestos is the prime culprit of this disease. However studies have shown that a secondhand form of the disease is linked to families of asbestos workers.
If you contract this disease, you may exhibit a number of symptoms. You chest may hurt. You may also have trouble breathing. Weight loss often occurs.
In the future I will discuss discussion and treatment of mesothelioma. However be aware that once diagnosed, the prognosis is dim. I have found that WikiPedia is a good source for basic information about the disease.
