Evolution is slow and progressive. Once the disease develops, the condition continues even if the patient is removed from the contaminated atmosphere. The most common complications are pulmonary emphysema, chronic bronchitis, spontaneous pneumothorax, respiratory failure, chronic pulmonary cord.
Pulmonary tuberculosis is one of the most severe complications. The clinical form is called silicotuberculosis and occurs in the advanced stages of silicosis.
Prevention is the basis of treatment. It is also based on the mandatory hiring requirement, periodic preventive checks and especially the removal from the silicogenic environment of the patients found in early stages.
