Idiopathic pulmonary fibrosis (IPF) is a progressive condition causing lung scarring, making breathing increasingly difficult.

IPF is the most common type of pulmonary fibrosis.

The clinical course of IPF can be unpredictable, but its five-year survival from diagnosis is comparable to, or even worse than, a number of common cancers.
