SOUTH BEND, Ind.- Firefighters nationwide are encouraged to enroll in an online system as part of the largest effort to support and further understand cancer in the fire service field.

Launched by the CDC through its National Institute for Occupational Safety and Health (NIOSH), the National Firefighter Registry (NFR) is designed to identify details about firefighters' work and match them with cancer information provided by state registries.

Enrollment takes approximately 30 minutes to complete and can be done by following this link.

Participation is voluntary and all U.S. firefighters are asked to enroll, whether or not they have a cancer diagnosis.
