A total of 453 FDNY members have died from World Trade Center-related illnesses as of September 2026, surpassing the 343 firefighters killed on September 11, 2001. More than 12,000 FDNY members have been diagnosed with at least one WTC-related condition, and nearly a quarter of them have developed cancer.
9/11 First Responder – Introduction
9/11 first responders, the firefighters, police officers, EMTs, and construction workers who rushed toward Ground Zero rather than away from it, now face a health toll that has grown to outweigh the losses of the attack itself. Twenty-five years after the towers fell, the toxic mix of pulverized concrete, asbestos, jet fuel residue, and combustion byproducts that blanketed Lower Manhattan continues to claim the lives of the men and women who spent weeks or months working in that debris field. The FDNY alone has now lost more members to World Trade Center-related illness than it lost on the day of the attacks.
That milestone, reached in September 2026 around the 25th anniversary, has renewed national attention on exactly how many responders were exposed, how many have since fallen ill, and how the federal government continues to track and treat this aging population of Ground Zero veterans. Newly released records, updated FDNY health reports, and fresh federal program data released around the anniversary offer the clearest picture yet of the scale of illness among the people who answered the call on September 11, 2001, and in the recovery effort that followed.
The story behind these numbers extends well beyond the FDNY, even though the department’s own detailed medical monitoring program has produced the most granular public data available. Police officers, emergency medical technicians, ironworkers, utility crews, and thousands of volunteers who spent time in the debris field over the following months all share overlapping risk with the more heavily documented firefighter population. Piecing together their combined experience requires drawing on several distinct data sources, each tracking a different slice of the same underlying exposed population.

These interesting facts about 9/11 first responders capture a grim statistical crossover point that took a quarter-century to arrive. The climb from 343 FDNY deaths on the day of the attacks to 453 subsequent deaths from illness means illness has now claimed more FDNY lives than the attack itself, a threshold department officials had long anticipated but hoped medical advances might prevent.
The scale of illness reaches far beyond fatalities. With more than 12,000 FDNY members carrying at least one certified WTC-related condition, and nearly a quarter of them diagnosed with cancer specifically, the health consequences of Ground Zero work now touch a population many times larger than the number who have died.
Placed alongside the broader WTC Health Program’s ~50,000 total certified cancer diagnoses across its full responder and survivor population, the FDNY’s roughly 5,000 cancer cases represent a meaningful share of the overall cancer burden tied to the attacks, even though firefighters make up only a fraction of the total exposed population documented across all covered agencies and civilian groups combined.

The population of 9/11 first responders extends well beyond FDNY firefighters alone. The city’s original World Trade Center Health Registry tracked roughly 34,000 rescue and recovery workers, a group that included firefighters, police officers, emergency medical technicians, construction and utility workers, and volunteers who spent time in the debris field during the recovery operation that stretched for months after the attacks. That same recovery effort followed a rescue operation in which FDNY crews pulled an estimated 30,000 people out of the Twin Towers before they collapsed.
Individual police officers who responded were issued personal exposure numbers by the NYPD in the days following the attacks, a form of documentation intended to formally certify their presence at Ground Zero for future health and compensation purposes. While no single, centralized figure captures exactly how many officers received such documentation, the practice reflects how early officials recognized that the health consequences of the response would likely extend for years, if not decades, after the immediate rescue and recovery work ended.
The composition of the original 34,000-person registry cohort also illustrates how broad the exposed population actually was. Beyond uniformed firefighters and police officers, the group included ironworkers who helped clear structural debris, utility crews restoring power and communications infrastructure, and volunteers who arrived from across the country to assist however they could. That diversity of occupations means the health consequences documented in later years have never been confined to any single profession, even though public attention has tended to focus most heavily on FDNY and NYPD personnel specifically.

The moment illness-related deaths surpassed the 343 FDNY members killed on September 11, 2001, had been building for years, with department officials tracking the toll climbing steadily each anniversary. By September 2026, that number had reached 453 FDNY members lost to World Trade Center-related cancers and respiratory illnesses, a toll department leadership described as a “somber milestone” in official statements marking the 25th anniversary.
Individual cases behind these statistics illustrate the pattern driving the overall numbers upward. EMT Hilda Vannata, who volunteered for recovery work in 2001 alongside her husband, an NYPD sergeant, died of pancreatic cancer she developed after her time at Ground Zero. Firefighter Robert Fulco died of pulmonary fibrosis, a chronic lung disease linked to prolonged exposure to the toxic dust that settled over Lower Manhattan. The FDNY’s memorial wall, which honors both those killed in the attacks and those who died later from related illness, has continued adding names each year, with 43 names added in a single recent update ahead of the 25th anniversary.
The pace at which new names are added has itself become a data point department officials track closely. Union leaders representing FDNY members have described the ongoing additions as evidence that the health toll from Ground Zero exposure has not slowed even a quarter-century after the attacks, with new diagnoses and deaths continuing to emerge among firefighters who worked extended shifts in the debris field during the weeks immediately following September 11.

FDNY Chief Medical Officer Dr. David Prezant, who was present at Ground Zero on the day of the attacks and has led the department’s long-term health monitoring efforts ever since, confirmed that more than 12,000 FDNY members have now been diagnosed with at least one illness tied to their World Trade Center exposure. Of that group, nearly a quarter have developed cancer, a proportion that has climbed steadily as the responder population ages into the decades of life when cancer risk naturally increases alongside the elevated risk tied to their original toxic exposure.
United States Veterans Statistics tracking service-connected disability rates among military veterans offer a useful point of comparison for understanding the scale of disability among 9/11 responders, since both populations represent groups whose service-related exposures have translated into long-term, federally tracked health and disability outcomes. Dr. Prezant reported that more than 2,100 firefighters and EMS personnel have retired on disability specifically due to World Trade Center-related illnesses since 2001, primarily driven by lung disease and cancer diagnoses that made continued active duty impossible.
Dr. Prezant himself represents a unique bridge between these statistics and the lived experience behind them, having been present at Ground Zero on the day of the attacks before spending the following twenty-five years leading the department’s medical monitoring efforts. His continued involvement has given the FDNY’s health reporting a level of institutional continuity rarely matched by other responding agencies, allowing the department to track individual members’ health trajectories across the full quarter-century since the attacks rather than relying solely on periodic snapshot studies.
Cancer Among 9/11 First Responders in 2026

| Total Cancer Diagnoses Certified (WTC Health Program, all members) | ~50,000 |
| FDNY Members With Certified Cancer | Nearly 5,000 |
| Share of FDNY Cancer Patients With Multiple Cancer Types | 26% |
| 5-Year Survival Rate (FDNY WTC-Related Cancer Patients) | 86% |

Cancer stands as the dominant illness category among 9/11 first responders, with roughly 50,000 total cancer diagnoses certified across the full WTC Health Program population, responders and survivors combined. Within the FDNY specifically, nearly 5,000 members have had a cancer certified as WTC-related, and 26% of those members have been diagnosed with more than one distinct cancer type, reflecting the breadth of the toxic exposure rather than a single dominant carcinogen.
Death Statistics in U.S tracking cancer’s role as a leading cause of death nationally provide useful context for interpreting the FDNY’s own survival data, since the department reports an 86% five-year survival rate among its members diagnosed with WTC-related cancer, a figure officials attribute directly to early detection made possible through mandatory, regular program screenings. Earlier registry research covering roughly 34,000 original rescue and recovery workers had already identified small but measurable increases in prostate cancer, thyroid cancer, and the blood cancer multiple myeloma compared to the general New York State population, findings that helped establish the scientific basis for the WTC Health Program’s ongoing cancer monitoring and certification process.
That 86% survival figure stands considerably higher than many national cancer survival benchmarks for comparable cancer types, a gap researchers attribute largely to the intensive, mandatory screening protocols built into the WTC Health Program specifically for its responder population. Because members undergo regular monitoring exams rather than relying solely on symptom-driven diagnosis, cancers are frequently caught at earlier, more treatable stages than would typically occur in the general population, a pattern FDNY officials have cited as one of the program’s clearest public health successes even amid the broader tragedy of the underlying exposure itself.

While FDNY data dominates public reporting due to the department’s detailed, decades-long tracking program, 9/11 first responders also include thousands of NYPD officers, construction and utility workers, and volunteers who spent time in the debris field during rescue and recovery operations. These groups are collectively covered under the same federal WTC Health Program framework, though the FDNY’s internal medical monitoring system, run by its own dedicated Bureau of Health Services, has produced far more granular and frequently updated public statistics than most other responding agencies have published.
Leading Causes of Death Statistics in US covering how cancer and respiratory disease rank among the nation’s top killers help frame why the WTC Health Program continues treating cancer and pulmonary conditions as its highest priority certification categories. Because exposure levels, protective equipment use, and time spent at Ground Zero varied significantly across police officers, ironworkers, utility crews, and volunteers, individual risk profiles differ considerably from the FDNY’s own well-documented experience, even though all these groups draw on the same underlying federal health program for monitoring and treatment.

The WTC Health Program, established under the James Zadroga 9/11 Health and Compensation Act of 2010, remains the primary federal mechanism through which 9/11 first responders access ongoing medical monitoring and treatment. As of June 30, 2026, the program was actively caring for 145,275 members, the majority of whom qualify as responders based on documented presence at Ground Zero, the Pentagon, or the Shanksville, Pennsylvania crash site during the response and recovery period.
For first responders specifically, program enrollment provides access to regular screening exams designed to catch cancer and respiratory conditions early, a feature FDNY officials have repeatedly credited with improving survival outcomes among members who do develop WTC-related cancer. As the responder population continues aging, and as newly released records like the recently disclosed 170,000 pages of Ground Zero air-quality data continue prompting fresh scrutiny of what officials knew about toxic exposure levels in real time, the program’s role in tracking, certifying, and treating this population is expected to remain central to the ongoing 9/11 health story for years to come.
