Asbestos Mesothelioma Definations
source(google.compk)The latest Asbestos News & Mesothelioma News articles published daily. Includes news on asbestos and the cancers caused by exposure to it - pleural mesothelioma (lung cancer) pericardial mesothelioma (heart cancer) and peritoneal mesothelioma (abdominal cancer).
Asbestos was once called a miracle material because of its toughness and fire-resistant properties. It was used as insulation, incorporated into cement and even woven into firemen's protective clothing...
The chances of developing lung cancer associated with asbestos exposure, asbestosis and smoking are dramatically increased when these three risk factors are combined, and quitting smoking significantly reduces the risk of.Poly (ADP-ribose) polymerase inhibitors may be a novel treatment strategy for patients with cancer that has become resistant to the commonly used chemotherapy drug cisplatin, according to data from a preclinical study.
Mesothelioma, more precisely known as malignant mesothelioma is a rare cancer of the mesothelial cells, most commonly those in the lining that covers the lungs (pleura). Mesothelial cells exist in the lining (membrane) that covers the outer surface of our body organs. The majority of people with mesothelioma have been exposed to asbestos at some time during their life.
Mortality reports on asbestos exposed cohorts which gave information on exposure levels from which (as a minimum) a cohort average cumulative exposure could be estimated were reviewed. At exposure levels seen in occupational cohorts it is concluded that the exposure specific risk of mesothelioma from the three principal commercial asbestos types is broadly in the ratio 1:100:500 for chrysotile, amosite and crocidolite respectively. For lung cancer the conclusions are less clear cut. Cohorts exposed only to crocidolite or amosite record similar exposure specific risk levels (around 5% excess lung cancer per f/ml.yr); but chrysotile exposed cohorts show a less consistent picture, with a clear discrepancy between the mortality experience of a cohort of xhrysotile textile workers in Carolina and the Quebec miners cohort. Taking account of the excess risk recorded by cohorts with mixed fibre exposures (generally<1%), the Carolina experience looks uptypically high. It is suggested that a best estimate lung cancer risk for chrysotile alone would be 0.1%, with a highest reasonable estimate of 0.5%. The risk differential between chrysotile and the two amphibole fibres for lunc cancer is thus between 1:10 and 1:50.
Examination of the inter-study dose response relationship for the amphibole fibres suggests a non-linear relationship for all three cancer endpoints (pleural and peritoneal mesotheliomas, and lung cancer). The peritoneal mesothelioma risk is proportional to the square of cumulative exposure, lung cancer risk lies between a linear and square relationship and pleural mesothelioma seems to rise less than linearly with cumulative dose. Although these non-linear relationships provide a best fit ot the data, statistical and other uncertainties mean that a linear relationship remains arguable for pleural and lung tumours (but not or peritoneal tumours).
Since asbestos-related disease has been identified by the medical profession in the late 1920s, workers' compensation cases were filed and resolved in secrecy, with a flood of litigation starting in the United States in the 1970s, and culminating in the 1980s and 1990s. A massive multi-district litigation (MDL) complex filing has remained pending in the Eastern District of Pennsylvania for over 20 years. As many of the scarring-related injury cases have been resolved, asbestos litigation continues to be hard-fought among the litigants, mainly in individually-brought cases for terminal cases of asbestosis and cancers. In the late 19th century and early 20th century, asbestos was considered an ideal material for use in the construction industry. It was known to be an excellent fire retardant, to have high electrical resistance, and was inexpensive and easy to use. The problem with asbestos arises when the fibers become airborne and are inhaled. Because of the size of the fibers.
