Mesothelioma risk after 40 years since first exposure to asbestos: a pooled analysis

Data from 6 cohort studies were evaluated to assess the ongoing risk of mesothelioma more than 40 years after initial environmental exposure to asbestos.  Among over 22,000 of those exposed, 707 cases of pleural mesothelioma were diagnosed.  The rate and risk increased until 45 years after exposure, then the rate of increase tapered off somewhat.
