Declining relative risks for lung cancer after cessation of asbestos exposure

J Occup Med. 1984 Jun;26(6):422-6. doi: 10.1097/00043764-198406000-00014.


All studies that provide follow-up information for workers more than 35 years after initial exposure to asbestos show a declining ratio of observed to expected lung cancer deaths at the end of follow-up. The most parsimonious explanation of this finding is that relative risk for lung cancer begins to decline sometime after cessation of asbestos exposure.
