In a new study, medical researchers at the University of Nebraska and Duke University investigated the relation between the size and shape of asbestos fibers and incidence of lung cancer among workers employed at asbestos textile mills. Asbestos, a mineral fiber, causes respiratory disease in humans including pleural abnormalities; asbestosis, a chronic scarring of the lungs; lung cancer and mesothelioma, a cancer of the lining of the chest cavity and abdominal cavity.
Writing in the May issue of the journal Occupational and Environmental Medicine, the researchers reported tracking the health and vital status of more than 6,100 workers employed at textile mills that used asbestos in North and South Carolina from 1940 to 1973. As part of the research, the researchers estimated the size of asbestos fibers the workers were exposed to, depending on their particular job, based on an analysis of 160 historical dust samples from the textile mills. Certain jobs have a greater occupational risk of exposure to asbestos.
The researchers observed an increased risk of lung cancer among textile workers exposed to asbestos fibers of all lengths and diameters. They noted that the risk of lung cancer increased as the length of the asbestos fibers increased. The research supports the hypothesis that lung cancer is associated most strongly with exposure to long, thin asbestos fibers.
People may be exposed to asbestos in workplaces or homes if products containing asbestos are disturbed and tiny asbestos fibers are released into the air. Asbestos fibers may get trapped in the lungs if inhaled and remain in the lungs for a lifetime. The fibers can accumulate and cause scarring and inflammation, leading to disease.
Asbestos is classified as a known cause of cancer by the U.S. Department of Health and Human Services, the U.S. Environmental Protection Agency and the International Agency for Research on Cancer.
Mesothelioma is the most common form of cancer associated with asbestos exposure. Symptoms of mesothelioma typically take 20 years to 40 years after exposure to asbestos. Most people diagnosed with mesothelioma and asbestos related disease are older workers, retired workers and veterans who were exposed to asbestos in a workplace or in the service.
