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. 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. Early screening by chest X-ray of people who are exposed to asbestos. Stopping further exposure to asbestos is indicated. Supportive treatment of symptoms includes respiratory treatments to remove secretions from the lungs by postural drainage, chest percussion , and vibration. Aerosol medications to thin secretions may be prescribed.
