Nov 10, 2019· Coal worker's pneumoconiosis, also known as black lung disease, still occurs in around 2 percent of coal miners and is associated with the formation of one- to two-millimeter nodules. There has been a recent increase in the incidence of severe black lung disease (progressive massive fibrosis) in young coal workers in Appalachia.

Background Coal is produced across 25 states and provides 42% of US energy. With production expected to increase 7.6% by 2035, proximate populations remain at risk of exposure to carcinogenic coal products such as silica dust and organic compounds. It is unclear if population exposure is associated with increased risk, or even which cancers have been studied in this .

Coal dust is made of carbon-containing particles, and coal miners are at risk of inhaling this dust. Coal miners may also be exposed to silica-containing dust because coal mining may involve some drilling into silica-containing rock. Workers exposed to graphite dust can also develop pneumoconiosis similar to CWP.
Coal workers' pneumoconiosis (CWP) is an occupational disease (type of pneumoconiosis) caused by exposure to coal dust free of silica (washed coal).Histologically, CWP is classified according to disease severity into simple (presence of coal macules) and complicated (with progressive massive fibrosis) 3,7.

The sample consisted of 2,511 black-coal miners with pneumoconiosis. These workers were registered in the National Register of Occupational Diseases from 1992 to 2001. The data on individual and occupational history of workers were linked with the data from the National Cancer Register and the National Population Register.
In a study of coal-miners suffering from lung cancer two features of special interest are recorded. The difficulties in diagnosis are illustrated by case reports. The two-year survival rate after surgical removal of the tumour is significantly better in coal-miners than in non-miners.
It is unclear whether CWP predisposes miners to developing RA, whether RA takes on a unique form in patients with CWP, or whether RA alters the response of miners to coal dust. Multiple rounded nodules in the lung appearing over a relatively short time (Caplan syndrome) represent an immunopathologic response related to rheumatoid diathesis.
Generally this paper deals with the same subject as the one above but it is based on experience of cases occurring among coal-miners in another coalfield in Great Britain, namely, South Wales, where the incidence of PMF is very high. Details are given of 5 illustrative cases. The author reaffirms from his experience that the clinical distinction between lung cancer and PMF is .

Objectives Working in mines and quarries has been associated with an elevated lung cancer risk but with inconsistent results for coal miners. This study aimed to estimate the smoking-adjusted lung cancer risk among coal miners and compare the risk pattern with lung cancer risks among ore miners and quarrymen. Methods We estimated lung cancer risks of coal and ore miners .
Lung cancer can also be an incidental finding, as a solitary pulmonary nodule on a chest radiograph or CT scan done for an unrelated reason. The definitive diagnosis of lung cancer is based on the histological examination of the suspicious tissue in the context of the clinical and radiological features.
