Asbestosis is fibrosis or scarring of the lungs caused by asbestos dust. Asbestosis develops 20 years or more after first exposure. It is necessary to breathe in large amounts of asbestos dust, usually over several years, to develop asbestosis.
Patients present with breathlessness on exertion. A cough is common. A chest X-ray and a CT scan are usually sufficient to confirm the diagnosis. Taking a sample of tissue from the lung, called a lung biopsy, is not usually necessary unless the diagnosis is in doubt. Lung function tests are performed to assess how badly the lungs are affected.
Asbestosis usually progresses slowly. It is generally resistant to drug treatment although corticosteroid and immunosuppressive drugs are tried occasionally.
Patients are at risk of lung cancer and malignant mesothelioma.
Asbestos causes the same types of lung cancer as are caused by smoking. The two hazards of smoking and asbestos act together to greatly increase the risk of lung cancer.
