MESOTHELIOMA is a cancer that is basically found in people who are exposed to asbestos environment in a more prolonged tenure. In the video at http://www.youtube.com/watch?v=YLW08jEGqWw, Dr. Robert Case says mesothelium consists of a solitary coating of compacted to cuboidal cells shaping the epithelial lining of the serous cavities of the human body together with the peritoneal, pericardial and pleural cavities. Prolonged presence of asbestos fibres in the parenchyma of the lung may effect in the diffusion of the visceral pleura from where the fibre can then be transferred to the pleural exterior, thus leading to the improvement of malignant mesothelial plaques. All these process happen within the human body, and one will get to know about the integration of his health only at a point of no return a person will get to know about the Mesothelioma.
