Asbestos-induced diseases are still major health problems, as a remarkably large number of workers have been exposed to asbestos over the past 50 years. Personal injury lawsuits against asbestos manufacturers number hundreds of thousands, and new cases are still being filed. Asbestosis is a complex issue, and although the broad outlines of asbestos-related diseases are well set, many important areas, especially pathology, are poorly understood. In Brazil, since 1940, asbestos has been commercially explored, producing around 200,000 tons/year, exposing about 10,000 workers in the mining activity, and an unknown number of workers in asbestos-cement industry. A study, with scientific appropriate investigation, with the purpose to evaluate the effects of asbestos exposure over the health of the mine workers in this country, was done by interinstitution researchers, and untitled "Morbidity and mortality among workers exposed to asbestos in mining activities -- 1940/1996". With the experience achieved in the course of this study, the objective of this report is to make an overview of asbestos-related diseases, mainly with respect to difficulties in establishing the histopathologic diagnosis.
