How is Asbestos tied to Mesothelioma?
1. How is Asbestos tied to Mesothelioma?
What Is Malignant Mesothelioma
Malignant mesothelioma is an aggressive cancer that causes tumors to form in the protective membranes lining the
thoracic, peritoneal and pericardial cavities and, in rare instances, the internal reproductive tracts of both women
and men. In all but a handful of the 2,000 to 3,000 cases of malignant mesothelioma diagnosed in the United
States every year, asbestos exposure is the cause of the disease.

Malignant mesothelioma is characterized by an exceptionally prolonged latency interval. Twenty to 50 years may
occur between the initial asbestos exposure and the time malignant mesothelioma is diagnosed. Because this
interval is so very long, the disease is rarely detected early enough for curative treatments to be an option. The
average survival time for a patient who is diagnosed with malignant mesothelioma is between four and 18 months.
Asbestos and Malignant Mesothelioma
Asbestos is a mineral that has been extensively used for centuries in a huge number of industrial applications.
Asbestos lawyer has properties that make it seem like an ideal insulator. Asbestos is lightweight, extremely strong
and impervious to flame, heat, sound, electrical conductivity and most types of chemical corrosion.
Unfortunately, under heavy use or when they degrade over time, asbestos-containing materials release asbestos
back into the air in the fibrous form in which the mineral occurs in nature. These asbestos microfilaments are razor
sharp; when workers in the vicinity of asbestos-containing materials inhale them, they lodge in workers’ lungs,
occasionally migrating to other parts of their bodies, where over time they precipitate inflammatory changes that
become the precursors to asbestos-related diseases including malignant mesothelioma.

Types of Malignant Mesothelioma
There are three main types of malignant mesothelioma.
Malignant Pleural mesothelioma: Pleural mesothelioma affects the lining of the lungs, or pleura. It's the most
common type of mesothelioma, found in 70 percent of all malignant mesothelioma patients.
2. Tumor growth causes a characteristic thickening of the pleural membranes that show up on imaging studies.
Tumors also cause the cells that produce the lubricating fluids that prevent friction among the components of the
respiratory system when they rub up against one another to overproduce, leading to pleural effusion, a buildup of
fluid in the chest. The median life expectancy for a patient diagnosed with pleural mesothelioma is between two
and four years.
Malignant Peritoneal mesothelioma: Malignant mesothelioma develops in the abdomen and accounts for 10 to 20
percent of all mesothelioma diagnoses. Medical scientists are not quite sure how asbestos fibers travel from the
lungs to the peritoneum. Some believe that asbestos fibers may be ingested on contaminated food or in secretions
that are coughed up and reswallowed, while others believe that asbestos fibers travel through the lymphatic system
to colonize parts of the body outside the lungs. The median life expectancy for a patient who has been diagnosed
with peritoneal mesothelioma is seven months.
Malignant Pericardial Mesothelioma: Pericardial mesothelioma is very rare: Only 200 cases of pericardial
mesothelioma have ever been diagnosed. Because the cancer is so rare, treatment regimens have not been
standardized and its characteristic tumors are so close to the heart, surgery is seldom an option. Scientists do not
understand the mechanism whereby asbestos microfibers are inhaled and then travel to the heart. The median life
expectancy for a patient diagnosed with pericardial mesothelioma is under six months.
