A layer made up of specialized cells or membrane called mesothelium covers the most of the internal organs. There are two layers of cells in mesothelium. Organs are surrounded by the first one which is surrounded by the second thick layer. Between these two layer a lubricating fluid is concealed which is produced by the membrane itself. This lubricant allows the organs to move smoothly against adjacent organs and structures (for example the expansion and contraction of lungs, beating of the heart etc…
Mesothelioma has different names according to the different location in the body. One of all those is peritoneum which covers most of the organs in the abdominal cavity. Pleura is the membrane which surrounds the lungs and lines the wall of the chest cavity and tissue called as Pericardium covers and protects the heart.
In a disease known as Mesothelioma or the cancer of the mesothelioma, cells become abnormal and divide enormously and with out any order leading to the development of tumors. The tumors of the mesothelial cells can be non cancerous i.e. benign or cancerous i.e. malignant. As nearly all mesothelial tumors are malignant, cancerous mesothelioma is often just referred to as mesothelioma. They can spread and damage nearby tissues and organs too. Therefore the cancer cells may also metastasize from their parent location to other parts of the body.
The lining or membranes of certain large cavities in the body are get affected by the malignant 2011 Mesothelioma. Some major organs in the body such as heart, lungs, abdomen and others are housed by these cavities, known as the serious cavities.
Malignant mesothelioma undertakes 3 forms.
1) Peritoneal Mesothelioma: It is in the Peritoneum or membrane surrounding the abdomen.
2) Pericardial Mesothelioma: It is in the Pericardium or lining surrounding the heart.
3) Pleural Mesothelioma: This the most common form of malignant mesothelioma which affects the lining of the lung cavity.
The majority cases of malignant mesothelioma are related with an earlier experience of fibrous minerals, of which asbestos is the significant. The mineral which occurs naturally like strong and flexible fibers which can be separated in the form of thin threads and can be woven are called as Asbestos. Asbestos has been commonly used in several industrial products, as well as cement, brake linings, roof shingles, flooring products, textiles, and insulation. Particularly through the manufacturing process, these are simply inhaled or swallowed throughout the manufacturing process as asbestos dust are small particles which hover in the atmosphere.
The time span between developments of mesothelioma from asbestos exposure is 35-40 years. In general people exposed to asbestos for a prolonged period of time can develop mesothelioma, though few individuals with just brief exposure can also developed mesothelioma as seen. Conversely, people heavily exposed are not developing mesothelioma.
In previous decades of the 1970s, huge amounts of asbestos were utilized in industrial construction and shipbuilding. It’s used was restricted by government, by optional materials making available. Regardless of these changes, asbestos was continued in use.
Professions which content with asbestos and usually related with the inception of mesothelioma afterward in life comprise asbestos production, insulation work, heating trades, shipyard work, and construction.
