Mesothelioma is a rare form of cancer, which is almost always caused by exposure to asbestos. This type of cancer happens when harmful, or malignant, cells develop in the protective lining that covers most of the body's internal organs. The most common sites for mesothelioma are in the chest or belly, where cells become abnormal in response to asbestos fibers that have embedded in the outer lining of the lungs or abdominal cavity (belly), or in the sac that surrounds the heart.

Back to topAnnual Mesothelioma Incidence Data
Annual cancer incidence measures can be used to identify trends and patterns of cancer incidence over time. Annual measures are only available at the state level. County level cancer incidence measures are available as five year aggregate data.
Measure Description:
- The Cancer Count is the number of newly diagnosed malignant cancers.
- The Crude Rate (Per 100K) is the rate of newly diagnosed malignant cancers per 100,000 population
- The Age Adjusted Rate (Per 100K) is the age adjusted rate of newly diagnosed malignant cancers per 100,000 population. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
5-Year Mesothelioma Incidence Data
Five Year incidence measures can be used to identify trends and patterns of cancer incidence over time and in different geographic areas. Five-year aggregate measures are available at the state and county level. Five-year aggregate data is used to reduce the presence of suppressed values due to small numbers; allowing display of data, and stabilization of rates to better evaluate trends. Even with this aggregation some values still need to be suppressed.
Measure Description:
- The Average Annual Count is the average number of newly diagnosed malignant cancers per year in the five-year period.
- The Crude Rate (Per 100K) is the rate of newly diagnosed malignant cancers per 100,000 Population during the five-year period.
- The Age Adjusted Rate (Per 100K) is the age adjusted rate of newly diagnosed malignant cancers per 100,000 Population during the five-year period. Age adjustment to the 2000 Standard US Census is done to allow direct comparison of rates in counties and state with different population age distributions.
