Pneumoconiosis (Black Lung Disease)

Pneumoconiosis is an occupational lung disease caused by inhaling coal dust. It is also known as Black Lung Disease. There are two types of pneumoconiosis— simple, known as coal workers' pneumoconiosis (CWP) and complicated, known as progressive massive fibrosis (PMF). Pneumoconiosis is a type of interstitial lung disease. In this type of disease: the lung is damaged (in this case, by coal dust); the walls of the air sacs are inflamed; and the lung stiffens from scarring of the tissue between the air sacs. There is no known treatment for pneumoconiosis, but doctors treat the symptoms and complications of the disease.
