Silicosis, caused by the inhalation of silica dust, will also cause scarring in the lungs.

Idiopathic Pulmonary Fibrosis. Idiopathic pulmonary fibrosis (IPF) causes scar tissue to grow inside your lungs. Usually, when you breathe in, oxygen moves through tiny air sacs into your bloodstream. From there, it travels to organs in your body. IPF scar tissue is thick, like the scars you get on your skin after a cut. It slows oxygen flow from your lungs to your blood, which can keep your body from working as it should.
