How does one get pulmonary fibrosis? is it genetic?

Unknown: At this time it is not known how pulmonary fibrosis occurs. It seems as if it is abnormal healing of the lungs resulting in an overgrowth of "scar tissue" from cells in the body known as fibroblasts. Approximately 1-2% of all fibrosis patients have familial pulmonary fibrosis (genetic cause) so it is rare to have other patients with the illness in your family.

Possibly: Pulmonary fibrosis is usually the result of chronic or recurrent inflammation of the lung, which subsequently leaves scarring in the lung, and can be due to environmental factors as well as genetic factors.
