Frequency of diagnosis
Annual incidence of malignant mesothelioma is 7-13 per 1,000,000 male patients with a history of asbestos exposure. This incidence is highest in locations relative to industries such as shipyards, i.e., the Pacific and Middle-Atlantic states.
Age at Onset
Mesothelioma is most commonly diagnosed in the 50-70 year age group, although specialists are now seeing many 30-40 year olds, raising speculation that these cases may be the result of second-hand or household exposure.
The incidence of mesothelioma is lower in women than in men, due largely to the fact that fewer women worked outside the home in the 40s, 50s, and 60s. Sharing households with spouses who worked with asbestos, or living in the vicinity of asbestos mines or product manufacturing facilities, tends to increase risk.
No racial predisposition to mesothelioma exists.
