What is Pulmonary Fibrosis?

Pulmonary fibrosis (PF) is a family of more than 200 interstitial lung disease (ILDs) that cause inflammation and/or scarring of the lungs.

About 30,000 Canadians live with PF. Approximately half of this group of people have Idiopathic Pulmonary Fibrosis (IPF), meaning the cause is uncertain or unknown.
