French Study Finds Exposure TIming Matters When it Comes to Mesothelioma Risk, According to Surviving Mesothelioma

Early on-the-job asbestos exposure appears to raise the risk for pleural mesothelioma more than overall exposure volume.

Younger Asbestos Exposure Most Dangerous

Mesothelioma Risk and Exposure Timing

...high doses during the first years and low doses thereafter were at higher risk of pleural mesothelioma..."

Environmental health researchers in Bordeaux, France say their new evaluation on the timing of asbestos exposure and mesothelioma risk finds that the younger a person is at first exposure, the more likely they are to develop malignant mesothelioma.

University of Bordeaux scientists used a job exposure matrix to determine that exposure in younger workers is even more dangerous when it comes to pleural mesothelioma development. that later exposure.

“Due to much stronger weights of early doses of asbestos exposure, subjects who accumulated 20 fibres/mL over the entire job history with high doses during the first years and low doses thereafter were at higher risk of pleural mesothelioma than those who accumulated most of the doses later,” writes lead study author Aude Lacourt.

The report in the journal Occupational and Environmental Medicine is based on an evaluation of the cases of 1,196 male asbestos workers and 2,369 men of the same age who had never been exposed.

“We have all heard cases of people who developed mesothelioma decades later after being exposed just briefly as a teenager,” says Alex Strauss, Managing Editor for Surviving Mesothelioma. “Then there are cases of long-time asbestos workers who never develop mesothelioma. These report is a reminder of the potential importance of timing, which is often overlooked.”
