Researchers Stumped as Asbestos-Related Illness Continues to Rise

Researchers at the Centers for Disease Control and Prevention report in a new study that cases of malignant mesothelioma are on the rise, and they don't understand why.
Malignant mesothelioma is caused by exposure to asbestos, a substance comprised of six naturally occurring minerals, that was commonly used before the 1980s in manufacturing, home insulation, cigarette filters, vehicle brakes and other commercial products.
The Environmental Protection Agency banned the use of most asbestos-related products in the United States beginning in the 1970s due to the health risks associated with it.
