Lung cancer in miners - CORE

The clinical, histological, and biological features of 157 lung cancers in coal miners and ex-miners are presented. In most respects—age, bronchoscopic appearances, histological type, and symptoms —the two groups are similar. A high incidence of dyspnoea in the miners was attributed to the concurrence of chronic bronchopulmonary disease.

The 171 miners with confirmed lung cancer were matched by age and pack year smoking history on a one to one basis with miners who did not have lung cancer. The years of underground mining experience (as a surrogate of coal mine dust exposure) was almost identical in both groups indicating that mining exposure does not increase the risk of lung cancer.

Lung cancer - Wikipedia

Lung cancer, also known as lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. This growth can spread beyond the lung by the process of metastasis into nearby tissue or other parts of the body. Most cancers that start in the lung, known as primary lung cancers, are carcinomas. The two main types are small-cell lung carcinoma (SCLC) and ...

As a result, lung cancer in miners was recognized as an occupational disease—and the miners therefore entitled for compensation—in 1926 in Germany and in 1932 in Czechoslovakia. While it was thought that chemical constituents of the ore that was produced, most notably arsenic, might be involved in the etiology of these lung cancers, it was early on suspected that “radium emanation” was ...
