Firefighters Face Increased Risk for Certain Cancers

Cincinnati—University of Cincinnati (UC) environmental health researchers have determined that firefighters are significantly more likely to develop four different types of cancer than workers in other fields.

 

Their findings suggest that the protective equipment firefighters have used in the past didn’t do a good job in protecting them against cancer-causing agents they encounter in their profession, the researchers say.

 

The researchers found, for example, that firefighters are twice as likely to develop testicular cancer and have significantly higher rates of non-Hodgkin’s lymphoma and prostate cancer than non-firefighters. The researchers also confirmed previous findings that firefighters are at greater risk for multiple myeloma.

 

Grace LeMasters, PhD, Ash Genaidy, PhD, and James Lockey, MD, report these findings in the November edition of the Journal of Occupational and Environmental Medicine. The UC-led research is the largest comprehensive study to date investigating cancer risk associated with working as a firefighter.

 

“We believe there’s a direct correlation between the chemical exposures firefighters experience on the job and their increased risk for cancer,” says LeMasters, professor of epidemiology and biostatistics at UC.

 

Firefighters are exposed to many compounds designated as carcinogens by the International Agency for Research on Cancer (IARC)—including benzene, diesel engine exhaust, chloroform, soot, styrene and formaldehyde, LeMasters explains. These substances can be inhaled or absorbed through the skin and occur both at the scene of a fire and in the firehouse, where idling diesel fire trucks produce diesel exhaust.

 

“Firefighters work in an inherently dangerous occupation on a daily basis,” LeMasters adds. “As public servants, they need—and deserve—additional protective measures that will ensure they aren’t at an increased cancer risk.”

 

The UC-led team analyzed information on 110,000 firefighters, most of them full-time, white male workers, from 32 previously published scientific studies to determine the comprehensive health effects and correlating cancer risks of their profession.

 

Risk for 20 different cancers was classified into three categories—probable, possible or not likely—patterned after the IARC’s risk-assessment model.

 

UC epidemiologists found that half the studied cancers—including testicular, prostate, skin, brain, rectum, stomach and colon cancer, non-Hodgkin’s lymphoma, multiple myeloma and malignant melanoma—were associated with firefighting to varying levels of increased risk.

 

“There’s a critical and immediate need for additional protective equipment to help firefighters avoid inhalation and skin exposures to known and suspected occupational carcinogens,” says Lockey, professor of environmental health and pulmonary medicine at UC. “In addition, firefighters should meticulously wash their entire body to remove soot and other residues from fires to avoid skin exposure.”

 

The research was supported in part by a grant from the Ohio Bureau of Workers Compensation. Study collaborators include UC’s Paul Succop, PhD, James Deddens, PhD and Kari Dunning, PhD, as well as Tarek Sobeih, MD, PhD, of Cairo University, and Heriberto Barriera-Viruet, PhD, of the Interamerican University of Puerto Rico.

UC to host symposium on socially just community research

March 2, 2021

Event: March 5, 2021 9:30 AM

On Friday, March 5, The Cincinnati Project (TCP) will host its seventh-annual symposium titled “The Art and Science of Socially Just Community Partnered Research,” sponsored by UC’s College of Arts and Sciences and The Taft Research Center. Director of the Center for Culture-Centered Approach to Research and Evaluation (CARE) Mohan Dutta will deliver the keynote speech. Based in New Zealand, CARE is a global organization dedicated to developing community-based solutions for social change, advocacy and activism, inspired by the conviction that health is a human right. Founded in 2016, TCP unites researchers from UC’s College of Arts and Sciences with community partners to benefit marginalized communities in Cincinnati, tackling economic, race, gender and health issues. Past TCP research has focused on high eviction rates in Hamilton County, resulting in city legislation to protect the rights of renters through an eviction prevention plan. In addition to the keynote speaker, the symposium will include discussion panels from area organizations such as Housing Opportunities Made Equal (HOME), the Urban League of Greater Southwestern Ohio, the Center for Closing the Health Gap, and UC faculty researchers. Topics will include ways in which community-based research can be conducted in socially just ways, in order to benefit the communities it is designed to serve. The symposium will be held virtually via Zoom from 9:30 a.m. to 1:30 p.m., and is free and open to the public. For more information or to register, please visit The Cincinnati Project.
