Asbestos-related Lung Diseases: A Brief Update

Health risks from asbestos exposures have been evaluated, considering past professional histories when exposures at workplaces were higher than today. A linear no-threshold (LNT) model has been applied, although its relevance is unproven. Fibers are often found in the lungs and pleura of deceased people. Fiber findings do not prove that a disease is caused by asbestos. It is reasonable to assume that a targeted search for mesothelioma and other asbestos-related conditions in asbestos workers resulted in an increased detection rate. Histological and immunohistochemical characteristics of malignant mesothelioma partly overlap with other cancers, which may contribute to the overdiagnosis in exposed populations. The etiology and differential diagnosis of malignant pleural mesothelioma as well as differences in carcinogenicity between different asbestos types are briefly discussed here. In the author rsquo;s opinion, current regulations applied in some countries are excessive and should be reconsidered based on independent research. The most promising way to obtain reliable information would be through lifelong bioassays. It can be reasonably assumed that the non-use of asbestos-containing brakes, fireproofing, insulation, etc. increases the harm caused by fires, traffic accidents, and armed conflicts.
