9/11's Death Toll Is Still Climbing, New Cancer Data Shows
The attacks didn't end on September 11, 2001. They're still ending lives today.
As the nation prepares to mark the 25th anniversary of the September 11 attacks, new data from the World Trade Center Health Program reveals a milestone nobody wanted to reach: for the first time, cancer cases among people who lived, worked, or attended school near Ground Zero have surpassed the number of cases among first responders.
Survivors — the office workers, residents, students, and bystanders who breathed the same air but never wore a badge or carried a hose — now account for 28,913 of the total cancer cases. First responders account for 28,131. The gap is 782 cases. Small in number, enormous in meaning.
The 25th anniversary commemoration will include a new moment of silence specifically to honor those who have died from cancer, respiratory illness, and other 9/11-related conditions — a recognition that the death toll from that day has never stopped climbing.
The Numbers Are Staggering
The total number of certified cancer cases linked to 9/11 toxins has risen from 3,204 in 2015 to 57,044 in 2026. That's a 1,680% increase in eleven years. Among survivors specifically, the increase is even sharper — from 694 cases in 2015 to 28,913 today. A jump of 4,066%.
There are currently 145,275 members enrolled in the World Trade Center Health Program. Sixty-seven percent of them are certified for at least one cancer linked to 9/11 toxins.
Attorney Michael Barasch, whose firm represents thousands of people enrolled in the program, offered the most gut-punch summary of where things stand: "Sadly, we lose roughly two clients a day and see a new cancer certification every 50 minutes. 9/11 did not end on 9/11. The cancer clock is ticking 24/7."
Why the Survivor Numbers Are Now Higher
The sheer math of population size explains a lot. Roughly 90,000 first responders were exposed at Ground Zero. The survivor population — downtown residents, office workers, students — numbered over 300,000. A far larger group breathed the same toxic air. More people exposed means more eventual cases, even if individual exposure levels were lower.
When the Twin Towers collapsed and burned for months, the buildings were pulverized into a massive toxic cloud containing over 70 known carcinogens — asbestos, benzene, jet fuel residue, heavy metals, pulverized glass and cement. Scientists ultimately identified more than 2,500 distinct contaminants in the air. Everyone in Lower Manhattan in the days and weeks after the attacks breathed all of it.
The cancers showing up now are partly a function of biology and time. Many carcinogens have latency periods of 10 to 25 years — meaning exposure in 2001 is producing diagnoses in 2020, 2022, 2025, and beyond. The survivor population, larger to begin with and now aging into the demographic where cancer becomes more common, is bearing the brunt of that biological timeline.
Rare cancers are surging specifically. Neuroendocrine cancers — rare tumors of the pancreas, bowel, lungs, or adrenal glands — have jumped 6% in a single quarter. Brain cancer is up 9% in the same period.
The People Who Don't Know They Qualify
Perhaps the most troubling dimension of the survivor data is how many people still don't know they're eligible for help.
The World Trade Center Health Program provides free lifetime medical care and monitoring for certified 9/11-related conditions. The September 11th Victim Compensation Fund provides financial compensation. Both programs exist specifically for survivors — not just first responders. But awareness has lagged dramatically in the survivor community, which is far more dispersed than the firefighter and police populations with organized unions and advocacy networks.
Many survivors don't realize that simply being in Lower Manhattan on or after September 11 — not just on the day of the attacks but during the months of cleanup and recovery when toxic air was still saturated throughout the area — may qualify them for both free healthcare and financial compensation. The legal exposure window for the Health Program extends through May 2002. Thousands of people who lived in Tribeca, worked in the Financial District, or attended school near the site may be eligible and have never looked into it.
The anniversary is a natural moment to check. If you or someone you know was in Lower Manhattan after September 11, 2001, visit the World Trade Center Health Program at cdc.gov/wtc or call 1-888-982-4748.
Twenty-five years. The towers are gone. Sadly, the deaths aren't.
