THE DIAGNOSIS OF LUNG CANCER IN COAL-MINERS WITH PNEUMOCONIOSIS 145 whereas a tumour can arise in any part of the lung, P.M.F. usually arises in the upper part, in either an upper lobe or the apex of a lower lobe. Thus a solitary lesion in a basal segment is more likely to be cancer, in which respect case 3 was exceptional. A large opacity in any part of one lung-field, in the absence of other

Lung disease and coal mining: what

Purpose of review: Coal mine workers are at risk for a range of chronic respiratory diseases including coal workers' pneumoconiosis, diffuse dust-related fibrosis, and chronic obstructive pulmonary disease. The purpose of this review is to describe coal mining processes and associated exposures to inform the diagnostic evaluation of miners with respiratory symptoms.

Coal workers' pneumoconiosis (CWP), also known as black lung disease or black lung, is caused by long-term exposure to coal dust.It is common in coal miners and others who work with coal. It is similar to both silicosis from inhaling silica dust and asbestosis from inhaling asbestos dust. Inhaled coal dust progressively builds up in the lungs and leads to inflammation, fibrosis, and in worse ...

The two main types are small-cell lung carcinoma (SCLC) and ...
