Naval Veterans Frequently Encounter Lung Cancer Linked to Asbestos Exposure Onboard

According to findings published in Scientific Reports, naval veterans, particularly those serving in the 1950s and 1960s, exhibit higher incidences of lung cancer linked to asbestos exposure in comparison to army and air force veterans in the U.K. and Australia.


Mesothelioma Among Veterans


Richard T. Gun, MBBS, from The University of Adelaide's school of public health in Australia, emphasized that asbestos-related diseases continue to be prevalent.

Gun highlighted the importance for clinicians to gather detailed information on potential asbestos exposure in individuals presenting with lung cancer or interstitial lung disease, advising caution regarding asbestos and other hazardous dusts as potential causes.

The research, conducted by Gun and Gerry M. Kendall, BSc, MSc, PhD, from the cancer epidemiology unit at the University of Oxford, analyzed data from U.K. and Australian veterans who served in the 1950s and 1960s.

Their study aimed to determine the prevalence of asbestos exposure-related cancer among naval veterans compared to their counterparts in the army and air force.

The study included four cohorts: U.K. participants (n = 6,305), Australian participants (n = 73,43), a U.K. control cohort (n = 2,613), and a contemporary cohort of Australian Korean War veterans (n = 5,102).

The analysis revealed a higher occurrence of mesothelioma among naval veterans than other military branches, as indicated by standardized incidence ratios (SIRs) across various cohorts.

Specifically, in the Australian test participant cohort, SIRs for mesothelioma were notably higher among navy veterans compared to army and air force veterans.

Similar patterns were observed in other cohorts, emphasizing the higher incidence of mesothelioma among naval personnel.

Moreover, the incidence of lung cancer also demonstrated higher standardized incidence ratios among naval personnel than among army and air force members in several cohorts. These findings underscored the heightened risk of lung cancer associated with asbestos exposure among naval veterans compared to other military branches.

The researchers also compared smoking-related conditions between navy and army personnel. Their analysis showed comparable rates of smoking-related conditions such as ischemic heart disease, COPD, and bladder cancer between navy and army veterans.

This suggested that the increased incidence of lung cancer in naval personnel was not likely linked to smoking habits.

The study results further highlighted that asbestos-related conditions, including asbestosis, were more prevalent among navy veterans compared to army or air force veterans.

In conclusion, Gun stressed the persistent existence of asbestos-related health risks despite asbestos import prohibition for several years.

He also urged clinicians to be vigilant in gathering occupational histories and seeking occupational hygienists' expertise when the significance of an exposure remains unclear.

This approach is essential not only for asbestos exposure but also for potential health effects stemming from other airborne hazards, such as engineered stone, diesel exhaust, and other respirable urban pollutants.

Asbestos Cancer happens to be the most devastating form of lung cancer. But do you know how it develops and the probable causes responsible to spread the dreaded ailment? Well, let's give you some insights about this form of cancer before proceeding further. Medical researches had  already   begun as early as 1935 to track down the most common causes related to the Asbestos cancer. After a series of extensive research, the factors responsible to spread this form of cancer was none other than asbestos exposure to your body.  During the research, it was established by the National Cancer Institute that the level of asbestos exposure should be minimized to check the disorder under control. So, more will be the asbestos exposure to your body, lesser time it will take to spread the ailment. In the year 1986, OSHA (Occupational Safety and Health Administration) confirmed without proclaiming any doubts that Americans who have to work with Asbestos are most prone to su...

Asbestosis: Causes, Symptoms, Treatment, & More

Image
In this document, we are going to uncover a number of aspects related to asbestosis . It's a serious complication caused due to asbestos exposure. There are some other complications related to the exposure of asbestos including mesothelioma . But first we would like to discuss one of the chronic conditions caused due to asbestos exposure called asbestosis. Asbestosis is basically a chronic lung disease caused by exposure to asbestos and cannot be cured. Symptoms typically include shortness of breath, coughing, and chest pain and tightness. The life expectancy of patients diagnosed with asbestosis varies, and it also increases the risk of developing cancer.     What Is Asbestosis? Asbestosis is a chronic lung ailment brought about by exposure to asbestos. It entails a gradual scarring of the lungs and falls under the category of interstitial lung diseases. When the body attempts to get rid the lungs of asbestos particles, scar tissue forms, resulting in painful or ch...
