Rising Cancer Toll Highlights Ongoing 9/11 Health Crisis

Escalating Cancer Toll 25 Years After the Attacks
Federal data show that diagnoses of cancers linked to the September 11, 2001 attacks continue to climb. Civilian cases have now overtaken those of first-responders, and the overall death count from 9/11-related illnesses exceeds the 2,977 fatalities on the day of the attacks. The World Trade Center (WTC) Health Program reports more than 57,000 certified cancer cases nationwide, with a sharp rise in new diagnoses over the past few years.
Background: Toxic Dust and Delayed Disclosure
In the months after the towers collapsed, city officials repeatedly assured residents that the air was safe. Recent releases of over 170,000 pages of air-quality reports reveal that asbestos and other hazardous particles were still detectable up to half a mile from Ground Zero ten months later. Internal city memos, including the “Harding Memo,” warned that the city could face tens of thousands of legal claims because health advisories encouraged premature return to the contaminated area. Mayor Zohran Mamdani has ordered the full set of documents to be posted online for the 25th-anniversary commemorations.
Data and Statistics: Surge in Diagnoses
- Northwell Health’s WTC program recorded 811 new cancer cases over a 42-month span, a 75 % increase from three years earlier.
- Certified cases at Northwell rose from 120 in 2023 to 262 in 2025 (118 % jump) and added 236 new cases in the first six months of 2026, about 5 % of all Northwell WTC patients.
- The broader federal WTC Health Program logged 235 new cancer diagnoses among responders in 2025, up from 177 in 2023; the first half of 2026 saw 132 new cases, putting the year on track to exceed 2025 totals.
- Approximately 30 % of Northwell’s responder cohort has been diagnosed with cancer, many with multiple primary sites.
- The most common cancers linked to exposure include prostate, skin, breast, urinary-tract, lymphoma (appearing roughly a decade earlier than in the general population), and lung cancer.
Official Statements & Responses
A CDC spokesperson affirmed that the WTC Health Program employs 82 federal staff and remains committed to high-quality care for responders and survivors. Dr. Craig Devoe emphasized that “screening is really, really important, and reporting new symptoms that are persisting.” Mayor Mamdani’s administration has allocated $34 million to review, redact, and publish additional unreleased documents related to post-9/11 environmental hazards.
Verbatim Quotes
- “They were all breathing the same toxic dust. They came back to work. They came back to school after the EPA assured us that the air was safe,” — Barasch.
- “These delays, sadly, cause a delay in diagnosis many of the times, and I don't have to tell you a delay in a cancer diagnosis can often be fatal,” — Michael Barasch
- “You're still at risk for a whole host of different cancers that take many, many years to develop,” — Dr. Jacqueline Moline, director of the Northwell World Trade Center Health Program
Conflicting Reports & Gaps
Sources differ on the magnitude of recent increases. News12 cites a “more than 3,200 %” rise in civilian cancer cases over a decade, while Northwell’s internal data show a 118 % jump in certified cases between 2023 and 2025. Newsday reports 235 new responder diagnoses in 2025, whereas ABC7 notes 811 new cases over a 42-month period. The variance reflects differing scopes (civilian vs. responder cohorts) and reporting intervals, leaving the precise national trend unclear.
