This bill allows firefighters to use federal grants to establish cancer prevention programs, including multi-cancer early detection testing and other preventative health screenings. The legislation authorizes $700 million in funding through the Assistance to Firefighters Grant program, with a cap of $1,750 per test per firefighter. Additionally, the bill creates a voluntary research partnership between the Federal Emergency Management Agency and the Centers for Disease Control and Prevention to collect and analyze de-identified test results from firefighters to identify cancer trends and potential causes in the profession. The funding and research initiatives address the elevated cancer risks firefighters face due to occupational exposure to hazardous materials.
