What is Asbestosis & Lung Cancer? I was so blur with this and tried to find some information from google and youtube. So now I know asbestosis exposure can also cause mesothelioma and lung cancer. Among people with asbestosis, lung cancer occurs most commonly in those who also smoke cigarettes, particularly those who smoke more than a pack a day. Wah, I almost smoke a pack a day, this looks really dangerous to me. I think it is time to plan to quit from smoke, otherwise I will be getting trouble in near future.
