As of my last knowledge update in January 2022, the exact number of mesothelioma cases worldwide can be challenging to pinpoint due to variations in reporting standards, diagnosis, and access to healthcare in different regions. Mesothelioma is a relatively rare form of cancer primarily associated with exposure to asbestos.
However, according to estimates from organizations such as the World Health Organization (WHO) and the American Cancer Society (ACS), there were thousands of new mesothelioma cases reported annually globally.
The majority of these cases are linked to occupational exposure to asbestos, which was commonly used in industries such as construction, shipbuilding, and manufacturing, among others, before its health risks were widely recognized.
It’s important to note that the number of cases may vary by country and region due to differences in asbestos usage, regulations, and reporting standards. Efforts to ban or limit asbestos use in various countries may also impact the number of new mesothelioma cases reported.
For the most current and accurate statistics on mesothelioma cases worldwide, I recommend referring to recent reports or databases from health organizations like the WHO, national cancer registries, or research institutions specializing in mesothelioma and asbestos-related diseases.
