New York thoracic surgeon: "For many patients 9/11 is not over"

The surgeon recounts treating numerous first-responders and construction workers who developed lung, esophageal cancer, leukemia, respiratory disease, and mesothelioma after inhaling dust and smoke from Ground Zero. He notes that the 25th-anniversary ceremony will include a moment of silence for those who died from these exposure-related illnesses, underscoring the ongoing health toll of 9/11.
