A collective study exposed a greater rate of asbestos-related lung cancers amongst British and Australian marine workers compared to other military branches, likely due to direct exposure aboard ships. This underscores the relentless risk of asbestos and the importance of rigid protections against harmful air-borne substances.
Research study shows increased lung cancer rates in Australian and british marine personnel due to asbestos direct exposure, highlighting the ongoing threats of asbestos and the requirement for strict protective steps.
A University of Adelaide and Oxford University research study has found asbestos exposure resulted in a higher occurrence of asbestos-related lung cancers in British and Australian marine workers than in other armed forces.
The information were collected from 30,085 United Kingdom and Australian personnel who served in the 50s and 60s, a time when asbestos-containing materials were present in British and Australian naval vessels.
Link Between Asbestos and Lung Cancer
Three of the four associates had actually previously been studied by the University of Adelaide and the UK Health Security Agency to determine the effects of radiation exposure from British nuclear testing; nevertheless, a raised occurrence of mesothelioma, a cancer highly linked to asbestos exposure, was seen in naval workers in all mates.
The University of Adelaides Dr. Richie Gun and Oxford Universitys Dr. Gerry Kendall were prompted by this finding to take a look at the dataset for the occurrence of lung cancers, which can likewise arise from asbestos direct exposure.

The fourth accomplice was Australian veterans of the Korean War, which had actually been studied by the Australian Department of Veterans Affairs and the Australian Institute of Health and Welfare.
” We discovered the lung cancer rate was greater overall in marine personnel than in the other armed services, and, while smoking stays the dominant reason for lung cancer, it is unlikely the excess could be explained by a greater smoking rate in the navy,” Dr. Gun stated.
Asbestos Exposure: A Major Concern
” Although real measurements of airborne asbestos levels were not available, and estimates are hard, we have actually concluded that the greater lung cancer rate in sailors was most probably caused by onboard asbestos direct exposure.
” This conclusion was enhanced by the event of deaths in sailors from asbestosis, a condition which is non-cancerous but is nonetheless disabling and potentially deadly.”
The researchers have estimated that the proportion of lung cancers associated with onboard asbestos exposure was of the order of 27 percent in Australian seafarers and 12 percent in British seamen.
Continuing Risks of Asbestos
While there is a ban on imports and strict regulative control of asbestos-containing materials in Australia, they still posture a risk to employees and some homeowners. There were 142 cases of asbestosis and 111 asbestosis deaths in 2021-2022 reported in the New South Wales Dust Diseases Register.
Dr. Gun said the impacts of asbestos direct exposure are likely being undervalued unless lung cancer is considered along with mesothelioma and asbestosis.
” Although it stays real that smoking triggers most lung cancers, other representatives such as asbestos can add to the incidence of cancer in an exposed population,” he said.
” Moreover, we understand from other studies that the mix of smoking and asbestos direct exposure has actually a boosted impact on lung cancer danger; this interactive result would have added to the observed lung cancer excess.”
The discovery of a link in between asbestos direct exposure and a higher occurrence of lung cancer is a timely tip of the need for defenses against direct exposure to other hazardous air-borne dusts.
” Strict control measures are required to protect employees potentially exposed not just to asbestos but to other hazardous dusts, such as dust from crafted stone now installed in many kitchen areas,” said Dr. Gun.
