Good morning @davidsmith76 From information I’ve found, most people exposed to asbestos don’t develop (asbestos based) mesothelioma. Mesothelioma is rare and can happen without exposure to asbestos.

From our Mayo Website (with the informational link attached below) “Most people with asbestos exposure never develop mesothelioma. This indicates that other factors may be involved in determining whether someone gets mesothelioma. For instance, you could inherit a predisposition to cancer or some other condition could increase your risk.”

The possibility for chances of this cancer can be impacted by the level of exposure and the length of time. It can take decades for the disease to develop.
Another informational article for you to read from Asbestos.com https://www.asbestos.com/mesothelioma/latency-period/#:~:text=How%20Long%20Does%20Mesothelioma%20Take%20to%20Develop%3F%20Mesothelioma,cases%20have%20been%20around%2060%20to%2070%20years.
