What causes silicosis?

Silicosis is mainly associated with long-term inhalation of dust with high silica content. There are no obvious clinical symptoms in the early stage. As the patient progresses, he may show clinical symptoms such as dyspnea, chest tightness, cough, etc. If it has developed into end-stage lung disease, lung transplantation may be required at this time to effectively prolong the patient's survival time.
