A report by doctors at the Yale School of Medicine regarding cases of pulmonary cancer in patients who had been diagnosed with asbestosis. The report is indicative of a growing realization among scientists of that time regarding the link between asbestos exposure and cancer. Exposure to asbestos can lead to a number of serious illnesses, including mesothelioma, lung cancer, asbestosis, stomach cancer, and throat cancer.

The Yale report examines the case histories of several individuals who developed cancer after being exposed to asbestos, detailing their work histories and the symptoms of their diseases.
