The major health problem caused by asbestos exposure, aside from cancer, is a lung disease called asbestosis. Irritation caused by the fibers can eventually lead to scarring (fibrosis) in the lungs. This can make it hard to breathe. The main symptoms of asbestosis are shortness of breath and a chronic cough.
