Medical Definition of ASBESTOSIS
: a pneumoconiosis due to asbestos particles that is marked by fibrosis and scarring of lung tissue
Lung disease caused by long-term inhalation of asbestos fibres. A pneumoconiosis found primarily in asbestos workers, asbestosis is also seen in people living near asbestos industries. Fibres remain in the lungs and many years later cause extensive scarring and fibrosis. Shortness of breath and inadequate oxygenation result; advanced cases include a dry cough. There is no effective treatment. The associated increased cardiac effort may induce heart disease. Cigarette smoking greatly exacerbates its symptoms. Lung cancer and malignant mesothelioma are more common with asbestos inhalation and asbestosis.
