Twenty-five years after the September 11, 2001, attacks, the WTC Health Program offers lessons about health effects that can persist long after a disaster. In a September 10, 2026, announcement, CDC described a new paper by program staff examining long-term outcomes, preventive care, and chronic disease management among people affected by 9/11.
The paper, published in the Journal of the American Medical Association, highlights the importance of ongoing, coordinated care. The findings are especially relevant to responders and survivors, as well as health professionals and organizations planning long-term support for disaster-exposed populations.
What the WTC Health Program report found
According to CDC’s summary of the paper, disaster-related health effects are often chronic, change over time, and involve multiple organs. People exposed to the attacks have a greater prevalence of chronic conditions and poorer health-related quality of life than the general population.
At the same time, CDC reports that people enrolled in the program have improved survival compared with those not enrolled. These findings describe both the continuing health burden associated with 9/11 exposure and the potential value of access to coordinated care.
The paper also emphasizes that effective disaster response requires connected systems of care and research—not only services immediately after an event. Following an affected population over time can help clinicians and researchers better understand changing health needs as that population ages.
Screening and cancer outcomes: What the numbers mean
In 2024, 54% of eligible program members who met U.S. Preventive Services Task Force criteria underwent lung cancer screening. CDC compared that figure with a 7.5% national screening benchmark and an actual U.S. lung cancer screening rate of 18% in 2022.
These figures refer to people meeting screening criteria, not every program member or everyone exposed to 9/11. The program and national screening-rate figures also come from different years. They should not be read as a recommendation that all responders or survivors need lung cancer screening.
CDC also cited program research showing that enrolled responders with cancer experienced mortality rates 26% to 64% lower than those of other New York residents living in the same area across several cancer types. The cancers included prostate, lung, kidney, and colorectal cancer.
That range describes comparisons across cancer types, not a single benefit that applies to every patient. The announcement does not provide enough study detail to determine how much of the difference was attributable to program care rather than other factors.
Who the program serves and what it covers
The WTC Health Program is a limited federal health program administered by CDC’s National Institute for Occupational Safety and Health. Launched in 2011, it is authorized through 2090.
It provides medical monitoring and treatment for certified WTC-related health conditions at no out-of-pocket cost to those directly affected by the attacks in New York, at the Pentagon, and in Shanksville, Pennsylvania. The announcement recognizes both responders and people who lived, worked, or attended school or daycare in the New York City Disaster Area.
The coverage description matters: the program is limited, and treatment coverage concerns certified WTC-related conditions. This announcement does not establish whether a particular person qualifies or whether an individual health condition is covered.
What this means for responders and survivors
The practical message is the importance of long-term monitoring and connected care. The report does not offer a universal screening schedule or an individual treatment plan. Questions about symptoms, screening eligibility, or care needs require professional medical assessment rather than conclusions drawn from population-level statistics.
Research is another part of the program’s mission. Members contribute by participating in studies that evaluate health outcomes and identify ways to improve care. CDC says those findings may also help people facing similar exposures in future disasters.
Frequently Asked Questions
Does every person exposed to 9/11 need lung cancer screening?
The announcement does not make that recommendation. Its screening statistic applies to eligible members who met U.S. Preventive Services Task Force criteria; individual eligibility needs clinical assessment.
What care does the program provide without out-of-pocket costs?
CDC describes medical monitoring and treatment for certified WTC-related health conditions. The release does not establish individual eligibility or coverage for a particular condition.
Why does follow-up still matter 25 years later?
The report describes disaster-related health effects as chronic, changing over time, and affecting multiple organs. Ongoing care and research help address the needs of an aging exposed population.
