What is Mesothelioma Cancer?
Mesothelioma is a rare and virulent form of cancer of the mesothelial surfaces that affects the lining of the lungs (the pleura), the abdominal cavity (the peritoneum) or the envelope of the heart (the pericardium).
Mesothelioma is caused by exposure to mineral fibers (such as asbestos).
Some were exposed to their work and others were seconded by members of the family who unwittingly brought fiber back home from work in their clothing, hair or skin.
Most often mesothelioma cancer is the result of an exposure of 20 to 50 years or more before.
Malignant mesothelioma is a fairly rare form of cancer that begins in the mesothelium, a membrane that covers and protects most of the body's internal organs.
The mesothelium is composed of two layers, one surrounding the organ itself, and the other forming a sac surrounding it completely. A small amount of liquid is normally produced between these two layers, lubricating the movement of the protected organs.Mesothelioma Law Firm
When normal mesothelial cells lose control and disseminate rapidly, they produce mesothelioma.
The most common form of mesothelioma is pleural mesothelioma.
The lining of the lungs occurs in the pleura. The other forms are peritoneal mesothelioma, reaching the peritoneum, coating the abdominal cavity and pericardial mesothelioma, pericardium.
The occurrence of this disease, sometimes referred to as asbestos cancer, which is the main risk factor for this type of cancer, is not indicative of a minimum threshold of exposure and its medical treatment has an impact Limited on the life expectancy of patients, usually from 12 to 18 months.
A real market of lawyers specializing in mesothelioma cancer exists in the United States, some keywords are very present such as for example: mesothelioma lawyers, mesothelioma attorneys, also mesothelioma treatments or even mesothelioma.
The first manifestations found on clinical examination are chest pain, often associated with shortness of breath and recurrent pleural effusion, usually haemorrhagic. The latency between the first exposure and the development of mesothelioma is rarely less than 20 years, often of the order of 30 to 40 years, or even more. There appears to be no exposure threshold value in relation to a risk of onset.Mesothelioma Law Firm
It has been described cases of pleural mesotheliomas occurring in the family environment close to workers exposed to asbestos, with subjects exposed as a result of contamination of living quarters or maintenance of dusty clothing.
Tobacco plays a synergetic cofactor role in the risk of occurrence of mesothelioma.
The consequences of mesothelioma cancer:
Although the incidence rates reported have increased over the past twenty years, mesothelioma is still a relatively rare cancer.
The incidence is approximately one case per million inhabitants. By comparison, populations with a high level of smoking can reach the incidence of more than one thousand lung cancer per million inhabitants.
The incidence of malignant mesothelioma currently reaches about 7-40 cases per 1,000,000 inhabitants in industrialized Western nations, depending on the extent of exposure of populations to asbestos in past decades.
The incidence in the United States was estimated to have reached one to 15 per 1,000,000 inhabitants in 2004.
The incidence is expected to continue to increase in other regions of the world. Mesothelioma occurs more often in men than in women and the risk increases with age, but this disease can occur in men or women at any age.
It can be noted that an epidemic of mesothelioma was discovered in three Turkish villages (Karain, Tuzkoy and Sarehidir).
It is responsible today for 50% of deaths there.
The health risks of cancer mesothelioma:
Occupational exposure to asbestos is the main risk factor for mesothelioma.
A history of exposure to asbestos exists in almost all cases. However, mesothelioma has been reported in some cases of individuals without known exposure to asbestos.Mesothelioma Law Firm
Asbestos has been widely used in many industrial products, including cement, brake pads, roof shingles, flooring, textiles, and insulation products. If tiny particles of asbestos float in the air, particularly during the manufacturing process, they can be inhaled or swallowed and cause serious health problems.
In addition to mesothelioma, exposure to asbestos increases the risk of bronchial cancer, causes asbestosis a pulmonary fibrosis (chronic non-cancerous disease), and other cancers, such as larynx and kidney tumors.
For one person the association of smoking and exposure to asbestos significantly increases the risk of developing upper airway cancer or bronchial carcinoma.
Apart from this particular case, smoking does not seem to increase the risk of mesothelioma. Some studies suggest that the simian virus 40 could act as a cofactor in the development of mesothelioma.
Exposure and cancer of asbestos:
The occupational sectors that led to exposure to asbestos were extraction units and industries employing asbestos because of its properties.
The extraction units
Manufacture of asbestos-based materials: manufacture of fibro-cement, textile asbestos, etc.
Insulation (in the building industry, in the manufacture of industrial furnaces, in the manufacture of thermal and refrigerating equipment, in shipyards) and thermal insulation (flocking with products containing asbestos has been banned)
The use of asbestos as heat protection (gloves, aprons, cords, blankets ...) in various industries: shipyards, iron and steel, foundry, glass making, building industry, etc.
Those who have directly worked with asbestos or asbestos products are at greatest risk of developing mesothelioma, however, mesothelioma has been reported in some individuals who have had minimal exposure.
Crafts at high risk of cancer development mesothelioma:
Carpenters in the field of iron
Manufacturers of the vehicle chassis
Workers in the building industry
Sheet metal workers
Since the ban on the manufacture of the import and marketing of asbestos-containing materials, it is the intervention on materials containing asbestos Which is the major concern, especially among all building professionals (asbestos removal work).
The cause of mesothelioma cancer
Mesothelioma is almost always caused by exposure to asbestos fibers. Many people have been exposed to the army and others by their occupation or, secondarily, by contact with exposed workers. Due to the latent state of the cancer, it may appear only 20 to 50 years or more after exposure.
A rare cancer?
Based on information obtained from the Finnish Institute of Occupational Health in Helsinki, the incidence of mesothelioma is expected to peak between 2010 and 2020.
Types of products that may typically contain asbestos:
The following products commonly contain variable rates of asbestos.
This list does not include all of them and is only a source of documentation.
Molded or preformed shield used in the thermal insulation of pipes and boilers
Insulation boards used as protection against fire, thermal insulation, separations and ducts.
- Asbestos jam used as a firewall in false ceilings
- Wrapped cardboard, paper and paper products used for the isolation of electrical equipment; Asbestos paper can also be used as a non-combustible backing on wood fiber boards
- Asbestos cement products in flat and corrugated sheets used to cover ceilings or walls; Cement products have also been used in gutters, rainwater pipes and water tanks
- Textured coatings
- Roofing material in bitumen
- Floor tile made of vinyl or thermoplastic.
Organizations dedicated to mesothelioma cancers exist:
Mesothelioma International is dedicated to the fight against mesothelioma - a global health crisis that has its roots in the use of asbestos by mankind. Although the use of asbestos has now been banned in the European Union and United States, it is estimated that 250,000 workers in USA alone will die of mesothelioma before 2029. We hope that this website will be useful for those everywhere that are affected by this epidemic.Mesothelioma Law Firm
