City should release cancer info on 9/11 first responders: de Blasio

The city should release even more details on cancer among police officers exposed to toxic 9/11 dust, Public Advocate Bill de Blasio demanded Monday.

Last week, the Bloomberg administration reported that 321 of the more than 40,000 cops and civilian NYPD employees who worked at Ground Zero documented having cancer.

The city, worried about releasing private medical information, finally presented its data to Mount Sinai Medical Center researchers after growing calls by the police union and de Blasio. The number affected is about 8% higher than initially believed.
