Mesothelioma cancer is generally caused by exposure to asbestos, as explained in the article at the link. The problem is that symptoms or signs of mesothelioma may not appear until 20 to 50 years (or more) after exposure to asbestos. Because of the time lag, the true danger of asbestos was not recognized until long after millions of workers had been exposed to it, particularly during WWII. From the article at the link, “Working with asbestos is the major risk factor for mesothelioma.[5] In the United States, asbestos is the major cause of malignant mesothelioma[6] and has been considered “indisputably”[7] associated with the development of mesothelioma.” Further:

Today, the official position of the U.S. Occupational Safety and Health Administration (OSHA) and the U.S. EPA is that protections and “permissible exposure limits” required by U.S. regulations, while adequate to prevent most asbestos-related non-malignant disease, they are not adequate to prevent or protect against asbestos-related cancers such as mesothelioma.[13] Likewise, the British Government’s Health and Safety Executive (HSE) states formally that any threshold for mesothelioma must be at a very low level and it is widely agreed that if any such threshold does exist at all, then it cannot currently be quantified. For practical purposes, therefore, HSE assumes that no such “safe” threshold exists. Others have noted as well that there is no evidence of a threshold level below which there is no risk of mesothelioma. . .  Again, there is no known safe level of exposure to asbestos as it relates to increased risk of mesothelioma.

The duration of exposure to asbestos causing mesothelioma can be short. For example, cases of mesothelioma have been documented with only 1–3 months of exposure.

In other words, asbestos is unsafe at any level.

More information can be found at the Mesothelioma Cancer Alliance and at their associated blog. The time from first exposure to asbestos and the manifestation of the disease is never less than 15 years and peaks at 30-40 years, with 32 years being the overall median.
