The Texas legislature has granted UTHealth Houston School of Public Health a significant $5 million funding allocation over the next two years to spearhead pioneering research focused on early detection and cancer risk among firefighters in Texas. Leading this critical initiative is Dr. Jooyeon Hwang, an associate professor in the Department of Environmental and Occupational Health Sciences. This study aims to unravel the complex health ramifications of chronic, repeated exposure to toxic chemicals commonly found in fire smoke, illuminating an occupational hazard that has long been overlooked despite its severe consequences.
Firefighters, by nature of their profession, are repeatedly exposed to a cocktail of hazardous substances resulting from combustion during fire events. This exposure increasingly contributes to long-term health issues, most notably cancer. Epidemiological data from institutions such as the Centers for Disease Control and Prevention (CDC) and the National Institute for Occupational Safety and Health (NIOSH) underscores that firefighters are at a 9% higher risk of developing cancer and suffer a 14% greater mortality rate due to cancer than the general population. Dr. Hwang’s research situates itself at the forefront of addressing this crucial public health concern, especially within the Texas firefighting community.
Between 2019 and 2023, there has been an alarming quintuple increase in cancer cases among Texas firefighters, escalating from 19 reported cases to 91. Given that Texas hosts over 55,000 firefighters, this rising trend demands dedicated investigation. While numerous previous studies have assessed cancer risks in firefighters across the United States, none have homed in specifically on Texas, a state characterized by unique environmental and occupational conditions. This grant thus provides a critical opportunity to generate localized, in-depth data that reflect the realities faced by Texan firefighters.

What distinguishes this research is its comprehensive inclusion of firefighter populations, spanning cadets, active service members, and retirees. By integrating longitudinal data across career stages, the study seeks to elucidate the cumulative and perhaps latent effects of occupational exposures on long-term health outcomes. Understanding the precise mechanisms by which fire smoke carcinogens infiltrate and affect the human body will be instrumental in developing tailored prevention, intervention, and policy strategies aimed at reducing cancer incidence in this dedicated workforce.
Dr. Hwang emphasizes the deep commitment and resilience of firefighters despite the evident health risks involved. The investigation aims not only to characterize exposure to known carcinogens but also to identify cancer biomarkers that might serve as early-warning signals for disease onset. This dual focus on toxicological profiling and biomarker discovery will push forward the frontier of occupational health science, offering new avenues for early detection and protection.
Importantly, this endeavor could not be realized without legislative support. The investment by Texas lawmakers reflects a growing recognition of the urgency of mitigating occupational cancer risks within fire services. Collaboration with firefighter associations, notably the Texas State Association of Fire Fighters and the Houston Professional Fire Fighters Association, further anchors the research in the operational realities and welfare concerns of firefighters themselves, ensuring that outcomes are meaningful and actionable.
John Riddle, president of the Texas State Association of Fire Fighters, publicly expressed gratitude for legislative champions such as Senator Brandon Creighton and Representatives Jared Patterson, Stan Kitzman, and Armando Martinez. He highlighted the bipartisan nature of the initiative and specifically lauded Senator Creighton’s efforts to double the project’s funding. This robust political and organizational backing is pivotal in sustaining long-term research programs of this magnitude.
The Houston Professional Fire Fighters Association, under the leadership of Patrick M. “Marty” Lancton, reinforced the personal and professional resonance of this study. The incidence of cancer among firefighters is not just an abstract statistic, but a lived tragedy, with many losing colleagues to this occupational disease. This research paradigm extends beyond epidemiology—it encompasses the urgent quest for tangible answers that will benefit current firefighters and future generations alike.
The research methodology integrates several innovative approaches. Alongside detailed work history analyses of firefighters from the Houston Fire Department, notably one of the nation’s largest fire departments with nearly 4,000 personnel, real-time environmental sampling will be conducted. Air samples collected at active fire scenes will be analyzed to quantify exposure levels to established and emergent carcinogens present in fire smoke. This rigorous environmental monitoring complements biological sampling regimes aimed at identifying urinary protein markers indicative of carcinogenic exposure and early-stage cancer.
Furthermore, the program envisions partnerships with local healthcare providers to facilitate free annual cancer screenings for firefighters. These screenings are designed to promote early detection, significantly improving prognoses and providing a potential model for occupational health surveillance nationwide. By coupling exposure assessment with clinical monitoring, the study establishes a multifaceted and translational research framework.
Chief Thomas Muñoz of the Houston Fire Department expressed optimism about the potential cultural shift this research may inspire within fire services. Historically, a stoic acceptance of risk has characterized firefighting culture, at times marginalizing safety concerns. The data-driven approach led by UTHealth Houston stands to inform evidence-based policy and prevention initiatives that can alter entrenched attitudes, safeguarding the health and longevity of firefighters.
Beyond Houston, the study will aggregate data from firefighters serving in other cities, expanding the scope and generalizability of findings. Data integration from the Texas Cancer Registry and additional databases will further strengthen epidemiological analyses, enabling comprehensive risk stratification and identification of particularly vulnerable subpopulations within fire services.
Dr. Hwang, an industrial hygienist and occupational health expert certified by the Board for Global Environmental Health Services, brings an extensive research portfolio to the project. Her recent 2024 publication in the journal Science of The Total Environment illuminates potential carcinogenic mechanisms induced by fire smoke, leveraging urinary proteomic profiles to decipher biological responses to toxic exposures. This foundational work underscores the translational potential embedded in the new study funded by Texas.
Leading co-investigators include Dr. Kristina Mena, a well-respected professor and regional dean who chairs the Department of Environmental and Occupational Health Sciences, and Dr. Miryoung Lee, an associate professor in the Department of Epidemiology. The administrative backbone is provided by the Southwest Center for Occupational and Environmental Health at the School of Public Health, where Dr. Hwang serves as both deputy director and director of the Industrial Hygiene Program, ensuring expert stewardship and interdisciplinary collaboration.
This landmark initiative represents a critical juncture in occupational cancer research, with outcomes that extend beyond Texas. By elucidating the carcinogenic hazards of fire smoke and enhancing early detection strategies, this program promises to reshape firefighter health protocols and underpin policies that can protect one of society’s most indispensable yet vulnerable groups.
