Since Mesothelioma is so fibrous, light and easily inhaled, it can lodge itself in the lungs and within the mesothelium. Where the individual fibers lodge themselves is where the tumors are formed. It is relatively agreed upon in the scientific community that it is usually very latent to develop mesothelioma from the asbestos exposure happened. That means that most scientists agree that asbestos exposure takes years and years to develop into mesothelioma.
“Inhaled asbestos fibers are known to be the cause of pleural mesothelioma, whereas ingested asbestos fibers are the cause of peritoneal mesothelioma. While the exact causal nature between asbestos and pericardial mesothelioma is not known, physicians and cancer researchers surmise asbestos fibers in the blood stream lodge in the outer layers of the heart’s ventricles and lodge in the pericardium. Once asbestos fibers reach the surface of the peritoneum or pericardium, the inflammation process is essentially the same as it is on the surface of the pleura.”
The main places that people were exposed were in naval shipyards with submarines or any maritime vessels, utilities services like power plants or railroads, and many other industrial type service areas such as the automotive industry.
