There are many different jurisdictions that operate differently. Some will recognize any cancer that is attributable to an IARC-recognized chemical, which allows for certain jurisdictions to be flexible with their coverage. For instance, in a lot of provinces, esophageal cancer is covered and colorectal cancer is covered, but anything in between is not, whereas tracts—digestive tract and reproductive tracts, whether male or female—are covered because the science has caught up.
As stated by a number of individuals who were in Lyon and participated in the reclassification of firefighting as an occupation for IARC, the science is settled. Out of all the different characteristics of carcinogenesis, half of them already have sufficient information that says firefighting is linked to them, whether it's chronic inflammation or oxidative stress. There are also some of the epigenetic effects and genotoxicity. We need an impetus for some of the acts, statutes and legislation to catch up.
