Asbestosis   

Overview | Symptoms | Treatment | Prevention

Alternative names:

Pulmonary fibrosis - from asbestos exposure; Idiopathic interstitial pneumonitis - from asbestos exposure

Definition:

Asbestosis is a respiratory disease caused by inhaling asbestos fibers.  Asbestosis is one form of lung disease related to asbestos inhalation.  Inhalation of asbestos fibers can cause a variety of diseases, from thickening of the lining of the lungs, which is usually asymptomatic, to malignant mesothelioma (a cancer arising from the lining of the lung). 

Causes and Risks

Inhaling asbestos fibers can cause scar tissue (fibrosis) to form inside the lung. Scarred lung tissue does not expand and contract (elasticity) normally. The severity of the respiratory disease depends upon the duration of exposure and the amount inhaled.

Asbestos fibers were commonly used in construction before 1975. Asbestos exposure occurs from asbestos mining and milling industries, construction, fireproofing, and other industries. In families of asbestos workers, exposure can also occur from particles brought home in the worker's clothing. Asbestos-related disease includes pleural plaques (calcification), malignant (cancerous) tumor called mesotheliomas--see mesothelioma (malignant), and pleural effusion. Mesotheliomas may develop 20 to 40 years after exposure. More than 9 million workers are at risk of developing this disease. Cigarette smoking increases the risk of developing the disease. The incidence is 4 out of 10,000 people.
