As of July 31, 2026, 9,677 first responders and survivors have died of illnesses tied to 9/11, according to September 11 Victim Compensation Fund data. That total includes 5,892 deaths attributed to cancer and is more than three times the 2,977 people killed on the day of the attacks.
World Trade Center Health Program figures also show about 57,000 certified cancer diagnoses among enrolled responders and survivors. Advocates note the true toll is likely higher because not everyone exposed has enrolled or had a death certified as 9/11-related.
