There are approximately 2,000-3,000 new cases diagnosed per year in the United States. It is most often seen in men over age 65, although any
age may be affected. According to OSHA, 1.3 million employees face significant asbestos exposure (most common cause of mesothelioma) in the
workplace. People with mesothelioma often show no signs or symptoms for 30-50 years. Once a person begins to show signs and symptoms, the disease
is usually quite progressed, with an average life expectancy of a few months to a couple of years remaining. Those who are at greatest risk of
developing mesothelioma are in contact with asbesstos, particularly in a dust form, like during asbestos removal. Workers who are most at risk are
miners, factory workers, insulation manufacturers, railroad workers, ship builders, gas mask manufacturers and construction workers. The families of
these workers are also at risk if the worker brings home asbestos dust on his or her clothing or hair.
