Although the carcinogenic properties of asbestos are presently attracting a good deal of attention, asbestosis is still the earliest lung disease resulting from exposure to it and its incidence in an exposed population is the most useful indicator of the degree of dust control exercised over a period of time. The diagnosis of asbestosis depends upon: (1) An adequate occupational exposure history. (2) Physical signs of pulmonary fibrosis. (3) Progressive radiological changes. (4) Confirmatory measurements of altered lung function. Asbestosis is a clinical entity and is readily diagnosed when all the above-mentioned criteria are met. Problems in diagnosis are encountered when one or more of the diagnostic criteria listed above cannot be substantiated. At the present time every effort is made to diagnose the disease in its early stages in the hope that removal from further exposure will prevent the direct and indirect complications.
尽管石棉的致癌特性目前备受关注，但石棉沉着病仍是因接触石棉而引发的最早的肺部疾病，在接触人群中的发病率是一段时间内粉尘控制程度最有用的指标。石棉沉着病的诊断取决于：（1）充分的职业接触史。（2）肺纤维化的体征。（3）进行性放射学改变。（4）肺功能改变的确认性测量。石棉沉着病是一种临床病症，当满足上述所有标准时很容易诊断。当上述一项或多项诊断标准无法证实时，就会遇到诊断问题。目前正在尽一切努力在疾病早期进行诊断，希望脱离进一步接触能预防直接和间接并发症。
