Asbestosis is a lung disease caused by exposure to asbestos dust. Inhaling asbestos dust can cause scarring in the lungs and in the pleural membrane (lining) that surrounds the lungs.
People with asbestosis have difficulty breathing, often have a cough and, in severe cases, have an enlarged heart.
Symptoms usually occur 10 to 20 years after exposure to asbestos dust. Symptomatic treatment such as oxygen therapy may help, but the lung damage is not reversible.
