Occupational Lung Diseases American Thoracic Society
While it is well known to cause lung cancer and mesothelioma, asbestos also results in other diseases. Asbestosis is a scarring, or fibrotic lung, disease. The most common manifestation of asbestosrelated disease is in the pleura. Pleural plaques are areas of thickened fibrous tissue, which often calcify.
