According to a new study published in Lung Cancer, textile workers that are exposed to asbestos have an increased risk of dying of lung cancer, mesothelioma and all forms of cancers. The cancer mortality correlated with the level of occupational exposure to asbestos. The researchers also found that the incidence of cancer was more pronounced among those workers who had high exposure to asbestos and were also smokers. The study helps to support the National Cancer Institute claims that while cigarette smoking alone has no known causative affect on mesothelioma incidence, the combination of smoking and asbestos exposure significantly increases the risk.
The researchers, based at The Chinese University of Hong Kong, tracked the employment and health status of 577 Chinese textile workers exposed to chrysotile asbestos from 1972 to 2008. The workers were then categorized into groups with high, medium or low exposure to asbestos based on their job titles and workplaces. Among the workers, there were 259 deaths including 53 deaths from lung cancer and two deaths from mesothelioma, an asbestos-caused cancer of the lining of the lung or abdomen.
The researchers found that the workers with high exposure to asbestos were twice as likely to die of lung cancer as those in the low exposure group, and one-and-a-half times as likely to die of any form of cancer.
On the heels of this study, Reuters reports that the World Bank has warned China that chronic non-communicable diseases (NCDs), including lung cancer, account for over 80 percent of all deaths in China, and unless they increase efforts to fight them the country risks an economic slowdown.
China has 300 million smokers, the world?s largest number, and both the World Bank and Lung Cancer have identified the increased risk of cancer among smokers. Stepping up access to smoking cessation programs and efforts to limit asbestos exposure among workers will lower health expenditures while also improving the health of the residents.
In a study in Environmental Health Perspectives researchers identified an underdiagnosis and underreporting of mesothelioma as a problem in countries with high cumulative use of asbestos, including China. The World Health Organization (WHO) estimates that asbestos causes approximately half of all deaths from occupational cancer. 125 million people worldwide are exposed to asbestos in the workplace.
