Hello. Exposure to cement dust increases the risk of development of lung cancer. The risk increases with the increase in years of work. If an average person has 1% risk of developing lung cancer, in cement factory workers, the risk rises to 1.4%. In a Korean study, out of 2500 cement factory workers,total 120 developed some type of cancer, 38 developed lung cancer. Try and reduce exposure to dust by putting on a protective mask at all times covering your nose and mouth. Also keep away from tobacco in any form including bidi, cigarettes and you should be fine. Hope this helps. Thanks.
