Asbestosis is a long-term (chronic) lung disease that can get worse over time. It is caused by breathing tiny asbestos fibres into the lungs. The fibres scar the inside of the lungs, which makes it hard to breathe.
Many years may pass between the time you are exposed to the fibres and when you feel the effects of the disease. The amount of time can depend on how long the exposure was and how many fibres you breathed in.
Smoking makes the disease get worse faster and increases the chances of it leading to lung cancer.
Asbestos is a material that was commonly used for insulating and soundproofing older homes and buildings. It was also used as a material in manufacturing. Many people have been exposed to asbestos while working in mining, construction, and the military, and by removing asbestos from old buildings.
