More than 5,400 people have been diagnosed with cancers linked to the attacks of September 11, 2001, according to the US government. The number could be higher, as the current total reflects only those who have enrolled in a 9/11 federal health program.
The World Trade Center Health Program, run by the Centers for Disease Control and Prevention, has counted 5,441 people diagnosed with cancers believed to be associated with the 9/11 attacks, as of June 30.
Most of those diagnosed were emergency responders, recovery or cleanup workers, and volunteers who worked during or after the attacks at the World Trade Center in New York; the Pentagon in Arlington, Virginia; and the Shanksville, Pennsylvania site where the fourth hijacked airliner crashed. More than 700 people lived, worked or attended school near the World Trade Center on September 11, 2001, or in the months immediately after the attacks.
Nearly half of those diagnosed with cancer are between the ages of 55 and 64.
