Silicosis is a lung disease caused by inhaling tiny crystalline particles of silica, or silicon dioxide, often linked to work environments like mining, construction, stonework, and sandblasting. The disease leads to symptoms such as coughing, inflammation, and fibrosis (scarring) and is classified under pneumoconioses, a group of lung conditions caused by inhaling dust. Silicosis can be chronic, developing over more than 10 years of exposure; subacute, occurring in two to five years with heavier exposure; or acute, which can happen within months of intense exposure. Although silicosis is irreversible and has no cure, treatments are available to manage symptoms.
