Firefighters and other first-responders from across all boroughs in New York City and beyond raced to the scene to help. That day, the New York Fire Department lost 343 of their own. In the years since, and at least 250 firefighters have since joined the roll-call of the dead, felled by adverse health effects from toxic dust released into the air by the toppled towers. A report noted that 3,097 FDNY members had at least one cancer diagnosis related to 9/11 and hundreds were diagnosed with more than one cancer, writes Rosie DiManno.
