Most cases take at least 20 to 30 years for the symptoms to show up and this period often depends on how intense and how long was the asbestos exposure
In people who were subjected to heavy asbestos exposure, for instance, in asbestos miners and insulation workers, the latency period is generally between 12 and 20 years, sometimes maybe shorter.
About 27% of mill workers developed symptoms of asbestosis after 5-9 years of heavy asbestos exposure whereas those people who were exposed to a lower quantity of asbestos, the latency period was well over 30 years, as per a study. Therefore, the latency period for asbestosis may range from 10 to 40 years.
Imaging tests and screening can recognize signs of asbestosis even before the major symptoms develop, and for this reason, if you have been exposed to asbestos on the job, ensure that you have a consultation with a doctor specializing in asbestos-related illness.
