Asbestos
Cancer
While the term " asbestos cancer " most often refers to
mesothelioma, a number of other cancers are associated with asbestos exposure.
Lung cancer, for example, is a direct result of asbestos exposure, and some
studies have suggested an association between asbestos exposure and
gastrointestinal and colorectal cancer. Elevated risks for a number of other
cancers listed below continue to be investigated. According to the World Health
Organization, approximately half of all deaths from occupational cancer are
caused by asbestos.
Mesothelioma Cancer
Mesothelioma
cancer is the only asbestos-related cancer almost exclusively caused by
asbestos. Mesothelioma can develop after someone inhales or ingests elevated
amounts of asbestos over time. The inflammation and DNA damage that can result
from asbestos exposure may eventually lead to the formation of tumors in the
lining of the lungs (pleura) or abdominal cavity (peritoneum ). In rare cases, the lining of the
heart or testicles can be affected.
Asbestos-Related Lung
Cancer
Lung
cancer is the second most common cancer in the United States and the
Occupational Safety and Health Administration calls it “the greatest health
risk for American asbestos workers.” Asbestos-related lung cancers are diagnosed more
frequently than any other type of asbestos-connected disease. The Environmental
Working Group estimates that between 5,000 and 10,000 asbestos-related lung
cancer fatalities have occurred each year over the span of the last two
decades.
Unlike mesothelioma, the risk of lung cancer
is greater among asbestos-exposed smokers. The synergistic effect of smoke and
asbestos drastically weakens the lungs and makes smokers with past asbestos
exposure more likely to develop lung cancer. This substantially contributes to
the rate of asbestos-related lung cancer diagnoses.
Other Asbestos-Related
Cancers
Aside
from mesothelioma and lung cancer, asbestos has been associated with a number
of other cancers. Research is still determining the extent to which asbestos
can cause other asbestos cancers, but studies indicate that asbestos exposure
is associated with gastrointestinal and colorectal cancer. Additionally,
asbestos may elevate the risk of developing kidney, throat, esophagus and
gallbladder cancers.

Incidence
of Asbestos-Related Cancer
The
Environmental Working Group (EWG) states that mesothelioma, asbestosis
and asbestos-related lung and gastrointestinal cancers have claimed as many as
230,000 lives between 1979 and 2001. The following chart reflects the EWG’s
yearly morbidity estimates for three primary asbestos-associated cancers as
well as asbestosis, a non-cancerous condition that is commonly diagnosed in
asbestos cancer patients.
