September 11 is Still Producing New Mesothelioma Diagnoses

I've spent much of my career representing people harmed by asbestos, and I've come to know a hard truth about exposure: it doesn't respect timelines. Mesothelioma can take decades to appear, which means the health consequences of September 11, 2001, are still unfolding today – a quarter-century after the towers fell.

When the World Trade Center Towers collapsed, they didn't just release smoke and debris. They released a toxic plume containing asbestos fibers, which had been used throughout the towers' construction as fireproofing and insulation. First responders, recovery workers, students, office workers and residents in Lower Manhattan breathed that dust for weeks, often without adequate respiratory protection. While the attacks claimed thousands of lives that day, the consequences of that exposure continued long after the fires were extinguished.

The numbers tell part of the story

The federal World Trade Center Health Program, created by the James Zadroga 9/11 Health and Compensation Act, currently has more than 86,000 responders and survivors enrolled for monitoring and treatment of 9/11-related conditions. More than two decades after September 11, cancer remains one of the most significant health challenges facing those exposed to the disaster. Cancer is one of the most serious categories of illness the program tracks. As of March 2026 statistics, there are 54, 956 certified World Trade Center-related responder and survivor cancer cases, a stark reminder that the health consequences of 9/11 continue to affect thousands of Americans.

The science helps explain why

Mesothelioma is one of the longest-latency cancers known to medicine. NIOSH and the World Trade Center Health Program have determined that at least 11 years must pass between asbestos exposure and a mesothelioma diagnosis, but it is not uncommon for the disease to emerge 20, 30, or even 40 years later. For tens of thousands of people who lived, worked, studied, responded, or volunteered in Lower Manhattan, the window for asbestos-related disease remains open.

That reality is worth remembering as we mark the 25th anniversary of September 11th. We remember the 2,977 people who were murdered that day. We remember the first responders who made the ultimate sacrifice. But we must also remember those who spent days, weeks, and months searching the ruins, clearing debris, rebuilding, and helping their communities recover. Many of them carried the effects of that exposure with them for decades before illness appeared.

Today, new mesothelioma diagnoses continue to emerge among people exposed to the toxic environment surrounding Ground Zero. Their stories are part of the September 11 story, too. They remind us that the human cost of that day did not end in 2001, and that for many families, its consequences are still being felt twenty-five years later.

The passage of time may change how we remember September 11, but it does not change what happened, nor does it lessen the impact on those who continue to live with the consequences. Twenty-five years on, the science is clear: 9/11 asbestos exposure is still producing new mesothelioma diagnoses, and it likely will for years to come. Remembering September 11 means remembering them, too.
