firefighters; occupational disease; adenocarcinoma

HB 2231 presumes that certain cancers, including adenocarcinoma, are work-related for Arizona firefighters and fire investigators who meet specific conditions. It applies to current and former firefighters diagnosed with listed cancers (like adenocarcinoma, leukemia, or lung cancer) within 15 years of leaving hazardous duty service, provided they: passed a pre-employment physical without cancer signs, served at least five years in hazardous roles, and meet medical exam standards. The presumption can be challenged if evidence shows non-occupational causes (e.g., tobacco use outside work) contributed to the cancer. This bill expands existing occupational disease protections for firefighters, adding adenocarcinoma to the list of presumed work-related cancers under Arizona law.
