Firefighter cancer presumption in California
California's law names leukemia and presumes it is job-related, plus other cancers linked to exposure.
That law is Cal. Lab. Code § 3212.1. Workers' comp and disability retirement both use it.
Presumed means the law assumes your job caused the cancer, so your employer has to show it came from something else. Workers' comp (workers' compensation) is the insurance that pays medical bills and part of your lost pay when work makes you sick.
Conditions under California's law
- The law covers volunteers, plus partly paid and fully paid firefighters.
- You need to show that you were exposed at work to a known cancer-causing substance, one listed by IARC or the director.
- Your cancer must develop or appear while you serve, or within 3 months for each year served after you leave, up to 120 months.
- To qualify, you must actively fight fires as a member of a fire department or unit.
- For a job at a federal installation or a commercial airport, your injury must happen on or after January 1, 2026.
An employer may argue that something other than your work caused your cancer.

How do you file a workers' comp cancer claim as a firefighter in California?
- Put it in writing: tell your department you have cancer and you believe the job caused it. Save a copy for yourself.
- Send the claim to the California Division of Workers' Compensation (DWC) or the insurer your employer uses, and name the law that applies (Cal. Lab. Code § 3212.1) on your form.
- Collect your diagnosis, any physical exam results, your fire and exposure records, and the dates you were hired and served.
- Start soon. Workers' comp claims have time limits for telling your employer and for filing, and some are short.
