Silicosis is a condition caused by inhalation of silica dust resulting in lung fibrosis.
Silica is found in sand, rock and mineral ore. Occupational exposure may occur through mining, drilling, sandblasting or quarrying.
Crystalline/free silica (such as quartz) is a carcinogen and linked to lung cancer.
Radiographs may show small nodules or more widespread fibrotic changes.
Spirometry shows a restrictive pattern
