When silica dust is inhaled over time, the tiny particles cause scarring and inflammation. This leads to the formation of lung nodules, which may be a sign of lung cancer. The scarring can also become so severe it stiffens the lungs and makes it difficult to breathe, leading to pulmonary fibrosis or COPD.
