The International Agency for Research on Cancer (IARC) lately categorised occupational publicity as a firefighter as carcinogenic, altering the earlier classification of presumably carcinogenic. The reclassification got here after many new research, together with a number of led by the University of Arizona Health Sciences in collaboration with the Tucson Fire Department, provided proof that occupational publicity as a firefighter causes most cancers.
“The IARC, the foremost international body for cancer research, is saying that firefighting is definitely associated with cancer,” mentioned Jeff Burgess, MD, PhD, professor within the Mel and Enid Zuckerman College of Public Health and BIO5 Institute member. “This is a really important outcome that our research has helped to support, but it’s also just the beginning. Now it’s our job to work with the fire service to help way find ways of preventing these increased numbers of cancers.”
The International Agency for Research on Cancer, the most cancers company of the World Health Organization, convened a working group of 25 worldwide consultants and three invited specialists from eight international locations to assessment the scientific literature. They discovered enough proof that occupational publicity as a firefighter causes mesothelioma and bladder most cancers, and restricted proof that it causes colon most cancers, prostate most cancers, testicular most cancers, melanoma of the pores and skin and non-Hodgkin lymphoma. Dr. Burgess was one of many invited specialists who assisted the working group by gathering info on firefighter exposures.
Additionally, new mechanistic research discovered constant proof that occupational publicity as a firefighter met 5 key traits of carcinogens, offering robust mechanistic help for the brand new classification. Several of the findings, particularly about epigenetic and receptor-mediated mechanisms of most cancers, had been from research Dr. Burgess led in collaboration with the Tucson Fire Department, a company he has labored with for 3 many years.
Through this partnership with the University of Arizona Health Sciences and the Fire Fighter Cancer Cohort Study, the Tucson Fire Department grew to become a nationwide chief in firefighter most cancers analysis. One significantly impactful achievement was figuring out interventions to cut back firefighter exposures and thereby scale back their most cancers threat. The Tucson firefighters are actually sharing their profitable interventions with different hearth departments across the nation.
“I am so proud of the partnership with the University of Arizona Health Sciences and the Fire Fighter Cancer Cohort Study,” mentioned Darin Wallentine, retired deputy chief of security and wellness for the Tucson Fire Department. “During my time with the Tucson Fire Department and the Safety and Wellness Division, the Tucson Fire Department became a national leader in firefighter cancer research. Being named as a co-author in groundbreaking firefighter occupational exposure studies is a tremendous honor and a rewarding career achievement.”
More than 15 million firefighters worldwide are uncovered to a fancy combination of combustion merchandise from fires – polycyclic fragrant hydrocarbons, risky natural compounds, metals and particulates – diesel exhaust, constructing supplies equivalent to asbestos, and different hazards together with warmth stress, shift work, and ultraviolet and different radiation. In addition, using flame retardants in textiles and of persistent natural pollution together with per- and polyfluorinated substances in firefighting foams has elevated over time.
“The research that supports this new IARC classification gives us new insights into the risks firefighters face on the job. It’s another example of how public health research provides data to create a safer, healthier world,” mentioned Iman Hakim, MD, PhD, MPH, dean of the Zuckerman College of Public Health. “I’m so proud of Dr. Burgess and his team for the collaborative research they have done – and continue to do – with the Tucson Fire Department. This is an area where the college brings unique expertise that benefits first responders in Arizona and around the world.”
“The new classification gives even more emphasis to the need for exposure reduction and to look at other ways that we might be able to modify the effects of exposures,” Dr. Burgess mentioned. “We need to figure out how to prevent or reverse those effects, beyond just reducing exposures.”
