What causes asbestosis?
Breathing in asbestos dust causes asbestosis. When inhaled, the asbestos dust sits deep in your lungs and causes scars.
The more you come in contact with asbestos, the more likely you’ll get asbestosis. If you aren’t in contact with asbestos at your job, you have a very low chance of getting asbestosis. People who work with asbestos a lot have the highest chance of asbestosis, for example, people who tear down buildings and miners who dig up minerals that contain asbestos.
