Pulmonary Fibrosis (PF)

Pulmonary fibrosis (PF) is one of a family of related diseases called interstitial lung diseases that can result in lung scarring. As the lung tissue becomes scarred, it interferes with a person's ability to breathe. In some cases, the cause of pulmonary fibrosis can be found. But most cases of pulmonary fibrosis have no known cause. These cases are called idiopathic pulmonary fibrosis (IPF).
