More than 40,000 firefighters nationwide have now joined the National Firefighter Registry for Cancer, an effort by CDC's National Institute for Occupational Safety and Health to study and reduce cancer risk in the fire service. With this level of participation, the NFR is now the largest firefighter cohort in the nation dedicated to understanding occupational cancer risks and advancing prevention efforts to protect firefighters' health.

In the line of duty, firefighters are exposed to hazardous substances such as smoke and toxic chemicals during their work, which can increase their risk of certain cancers. The NFR collects detailed work history information and links it with state cancer registries to improve understanding of occupational cancer risks and guide efforts to prevent cancer among firefighters.

“This milestone represents more than just numbers. It demonstrates the fire service's unwavering commitment to understanding and reducing work-related cancer,” said Kenny Fent, Ph.D., CIH, NFR Team Lead. “Every firefighter who joins the NFR plays a vital role in advancing knowledge to help protect the health of all who serve.”

Enrollment is open to all U.S. firefighters—whether career or volunteer, active or retired, with or without a cancer diagnosis, and from all specialties. More information about the NFR is availablehereand firefighters can joinhere.

Whether diseases start at home or abroad, are curable or preventable, chronic or acute, or from human activity or deliberate attack, CDC’s world-leading experts protect lives and livelihoods, national security and the U.S. economy by providing timely, commonsense information, and rapidly identifying and responding to diseases, including outbreaks and illnesses. CDC drives science, public health research, and data innovation in communities across the country by investing in local initiatives to protect everyone’s health.
