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.

also called  white lung 

      lung disease that is caused by the prolonged inhalation of asbestos fibres. A type of pneumoconiosis, it is found primarily among workers whose occupations involved asbestos, principally mining, construction, and the manufacture of insulation, fireproofing, cement products, and automobile brakes. The disease is not limited solely to asbestos workers but is also known among people living near mines, factories, and construction sites.

      Asbestos fibres that have been inhaled remain in the lungs for years and eventually cause excessive scarring and fibrosis, resulting in a stiffening of the lungs that continues long after exposure ceases. Greater effort is needed to make the stiffened lungs expand during breathing, which results in shortness of breath and inadequate oxygenation of the blood. Persons with advanced cases of the disease have a dry cough. The increased cardiac effort needed to perfuse the lungs may induce a secondary heart disease called cor pulmonole. An increased incidence of lung cancer and of malignant mesothelioma (a rare cancer of the membrane lining the lungs) is also associated with asbestos inhalation and asbestosis. There is no effective treatment for asbestosis.

      Asbestosis appears after at least 10 years' exposure to asbestos. The first symptoms typically do not appear until many years after the initial exposure; shipyard workers exposed to asbestos during World War II began developing asbestosis in the 1960s and '70s. (Mesothelioma, by contrast, can develop after relatively little exposure to asbestos.) Cigarette smoking seriously aggravates the symptoms of asbestosis and increases the risk of cancer. The incidence of asbestosis increased after 1950, probably due to the increasingly widespread industrial use of asbestos. This use declined from the 1970s and had been prohibited in many countries by the 1990s owing to asbestos fibres' deleterious effects on the lungs. As a result, the incidence and severity of asbestosis has decreased sharply.
