A 62-YEAR-OLD man died from a rare form of cancer caused by exposure to asbestos over 24 years.
Joseph Peter Boulderstone died on June 1 this year of mesothelioma at Mount Edgecumbe Hospice in Porthpean Road, St Austell.
The disease develops from transformed cells originating in the mesothelium, the protective lining that covers many of the internal organs of the body.
An inquest in Truro on Tuesday heard Mr Boulderstone was exposed to asbestos at various times between 1965 and 1989 "without adequate protective clothing".
He had several jobs in this time, including as a maintenance and gas fitter. After his diagnosis he had undergone chemotherapy, but his condition deteriorated.
Coroner for Cornwall Emma Carlyon accepted the pathologist's report and concluded Mr Boulderstone's death was due to an industrial disease, mesothelioma.
