Abstract

Industrial talc has been widely circulated in the world for a long time. The pure talc has little effects on humans, but inhalation of talc contaminated with asbestos can causes severe asbestos-related diseases such as lung cancer and malignant mesothelioma. Herein, we represent a case of lung cancer after occupational exposure to industrial talc in the rubber manufacturing industry.
