Definition
Coal worker's pneumoconiosis is a lung disease caused by breathing in dust from coal, graphite, or man-made carbon for a long time.
Causes
Coal worker's pneumoconiosis occurs in 2 forms: simple and complicated (progressive massive fibrosis, or PMF).
Your risk of developing the disease depends on how long you have been around the coal dust. Most people with this disease are older than 50. Smoking does not increase your risk of developing this disease, but it may have an additional harmful effect on the lungs.
If coal worker's pneumoconiosis occurs along with rheumatoid arthritis , it is called Caplan syndrome .
Treatment
There is no specific treatment for this disorder. You should avoid further exposure to the dust.
Other Names
Black lung disease; Pneumoconiosis; Anthrosilicosis
Outlook (Prognosis)
The outcome for the simple form is usually good. In rare cases, the complicated form may get suddently worse. It rarely causes disability or death.
Prevention
Wear a protective mask when working around coal, graphite, or man-made carbon. Companies should enforce the maximum permitted dust levels.
Exams and Tests
The doctor will perform a physical exam and listen to your lungs with a stethoscope. A chest x-ray will be taken.
