What causes pulmonary fibrosis?

ANSWER

Pulmonary fibrosis is scarring in the lungs that makes it hard to get enough oxygen into your body. Usually, the cause is not known, which is called idiopathic pulmonary fibrosis. Sometimes it is caused by other diseases, your genes, or when you breathe in asbestos or other industrial dusts for a long time.
