The rate of new mesothelioma cases is going down because fewer people are exposed to asbestos.OverviewMesothelioma is a cancer that forms in the mesothelium, the thin tissue that lines many internal organs. Mesothelioma is a rare cancer—2,803 cases were reported in the United States in 2021. Exposure to asbestos causes most cases of mesothelioma.Asbestos was used in many consumer products, automobile parts, and building materials in the 20th century before scientists learned about its dangers to health. The potential for asbestos exposure in the United States peaked in the 1970s but has since declined as U.S. asbestos mines were closed and asbestos-containing products and materials were withdrawn from the market.The decline in asbestos exposure is reflected by declines in mesothelioma incidence rates. However, people can still be exposed to asbestos in some consumer products and older buildings.How mesothelioma is definedThe International Classification of Diseases for Oncology, Third Edition (ICD-O-3) defines mesothelioma with the following histology:* 9050 (mesothelioma).* 9051 (fibrous mesothelioma).* 9052 (epithelioid mesothelioma).* 9053 (mesothelioma, biphasic).* 9055 (multicystic mesothelioma).Mesothelioma is also defined by the part of the body it is found in, using ICD-O-3 anatomic site codes. The most common site is in the tissue around the lungs, called the pleura (ICD-O-3 anatomic site code C38.4). Mesothelioma may also form in:* the tissue in the abdomen (peritoneum; C48.0 to C48.8).* the tissue around the heart (pericardium; C38.0).* the tissue around the testicles (tunica vaginalis; C63.7).Table and figuresTable 1.

U.S. Cancer Statistics incidence data are from population-based registries that participate in CDC's National Program of Cancer Registries (NPCR) and/or the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program and met high-quality data criteria during 1999–2021 for the 2023 data submission period, covering 97% of the U.S. population (excluding data from Indiana, Mississippi, and South Dakota).The 2023 data submission, released in June 2024, includes new cancer cases diagnosed in 2020 and 2021, the first and second years of the COVID-19 pandemic. The missed cancer diagnoses resulting from disruptions in health services caused by the pandemic may have contributed to an observed decline in incidence for most cancer sites in 2020. The numbers of new cases diagnosed in 2021 are still a little lower than expected for some cancer types but have returned to pre-pandemic counts for other cancer types. Caution must be taken when examining trends to avoid incorrect interpretations of the effect of cancer prevention and early detection efforts. Observed downward trends may be due largely to the lower observed incidence in 2020.Footnotesa Percentages in Table 1 may not add to 100% due to rounding.b Based on cases with ICD-O-3 histology codes 9050, 9051, 9052, 9053, or 9055. 94% of cases were based on microscopic confirmation.c “Other” includes all other anatomic sites. The most common were lung and bronchus (C34.0 to C34.9; 66% of “other” cases); unknown primary site (C80.9; 14%); mediastinum (C38.1 to C38.3 and C38.8; 4%); soft tissue (C49.1 to C49.9; 4%); and testis (C62.0 to C62.9; 4%). Other sites made up less than 3% of “other” cases.d New cancer cases per 100,000 standard population.
