In the US: Annual incidence of mesothelioma is 7-13 per 1,000,000 male patients with a history of asbestos exposure. Approximately 1 in 1,000,000 North American patients with no asbestos exposure present with mesothelioma per year. The incidence of mesothelioma is lower in women than in men, probably because fewer women than men worked outside the home in the mid-20th century; therefore, they were exposed less to asbestos.
The incidence of mesothelioma is highest in the Pacific and mid-Atlantic states and may be related to the location of industries such as shipyards.
Internationally: The incidence
of mesothelioma in women is 2/1,000,000/year and in men is
10-30/1,000,000/year in industrialized countries where asbestos was used
widely. The incidence of mesothelioma varies greatly among nations and is
difficult to document in countries without mesothelioma registries. In
France, an estimated 950 new patients are seen per year. In the United
Kingdom (where a mesothelioma registry exists), incidence is expected to
peak in the year 2020 at 2700 deaths per year and is expected to decline
Malignant mesothelioma usually is fatal. Death usually occurs within 18 months of first onset of symptoms. Mesothelioma usually presents 30-40 years after asbestos exposure.
