A Mesothelioma - asbestos-related diseases
Asbestos is a group of minerals that course in the form of bundle of fibers occurs. These fibers can in thin threads, are resistant to heat, chemicals and are not conductors of electricity be converted. Asbestos is in fact of a silicon-based connection with several variants such as amphibole, chrysotile... Etc.
Asbestos, see the construction of cement, insulation, covers, boilers, steam pipes, hot water pipes and a host of other products. In the 1900s, asbestos to a number of respiratory diseases were linked, were together known as asbestosis. Later, in the 1950s, was the link between asbestos and mesothelioma. Asbestos is recognized now as one of the most potent carcinogens in our environment. But still, asbestos found in many everyday products (such as fireproof clothing, caulk, clutch plates, brake pads... etc..)
Who are at risk of developing mesothelioma?
Asbestos is particularly dangerous, those people who regularly work with her. When an asbestos-containing material is disturbed, the fibres in the atmosphere are and can be inhaled by people in this environment. Construction work (e.g. renovation of old buildings built with asbestos cement), pipe fittings and other such works can release asbestos fibres, which can then be inhaled by workers. Secondary exposure has also known to be on. Collected as dust on the clothing and hair of workers asbestos fibers can be inhaled by their family members. It is known that to 30-40 years down the line mesothelioma lead exposure from as low as two months is sufficient.
Factors, the the risk of developing mesothelioma
Several factors determine whether asbestos Mesothelioma Cancer will result in the future:
* Dose (how much asbestos is inhaled)
* Duration (length of exposure to asbestos)
* Type the asbestos fiber (for mesothelioma, amphibole fibers are dangerous, because they stay longer in the lungs and migrate the mesothelial layer).
* Individual risk factors such as smoking and existing lung conditions
How asbestos mesothelioma causes cancer?
After inhalation, asbestos caused cells die caused be the lungs to drawn. Asbestos fibres slowly working their way towards the alveoli, and from there into the mesothelium.
For a while now been scientists determine not the exact pathway the asbestos cancer cause. This is because asbestos is allegedly necrotic in nature (i.e. it kills cells). Dead cells will not multiply and produce tumors. It is only recently, in 2010, that this paradox was resolved. Asbestos fibres cause programmed cell necrosis the a molecule known as high-mobility group box 1 (HMGB 1) protein release. HMGB1 initiates an inflammatory reaction, which results in the production of mutagenic and tumor growth factors.
Mutagens damages the DNA of the cells and the parts, to regulate the cell reproduction. Cells start, uncontrollably to form tumors to reproduce. The growth factors promote the tumors to expand from it resulting in mesothelioma and lung cancer, depending on the location of the damage.
