Relation between asbestosis and bronchial cancer in amphibole asbestos miners.

Asbestos exposure, asbestosis, and asbestos-attributable lung cancer.

The study was designed to test the hypothesis that the risk of lung cancer from asbestos exposure is confined to persons with radiographic evidence of pulmonary fibrosis. Occupational and smoking histories were obtained from 271 patients with a confirmed diagnosis of primary lung cancer and 678 referents (279 with other respiratory disease and 399 with cardiac disease). Histories were reviewed ...

Asbestos, asbestosis, and lung cancer: observations in Quebec chrysotile workers.

One prospective epidemiologic study of asbestos cement workers with radiological small opacities has been cited as a rationale for attributing excess lung cancer to asbestosis. This approach could have considerable practical value for disease attribution in an era of decreasing exposure. However, a recent International Agency for Research on Cancer review concludes that the mechanism of product...

Lung, Tracheal and Bronchial Cancer in Nickel, Uranium & Gold Miners

Dr. Ronald A. House completed his B.Sc. (Genetics) and his MD, CM degrees at McGill University. He subsequently did training in occupational health at the University of Toronto. He was awarded his fellowship in occupational medicine (FRCPC) by the Royal College of Physicians and Surgeons of Canada in 1988. He also completed a M.Sc. degree in Clinical Epidemiology at McMaster University in 1986....

Cancer Mortality in Chinese Chrysotile Asbestos Miners: Exposure-Response Relationships

OBJECTIVE This study was conducted to assess the relationship of mortality from lung cancer and other selected causes to asbestos exposure levels. METHODS A cohort of 1539 male workers from a chrysotile mine in China was followed for 26 years. Data on vital status, occupation and smoking were collected from the mine records and individual contacts. Causes and dates of death were further verif...

Is asbestos or asbestosis the cause of the increased risk of lung cancer in asbestos workers?
