Cancer data reveal cases rise in 9/11 workers

The number of cancer-stricken NYPD employees who worked at Ground Zero is 8 percent higher than originally thought, The Post has learned.

The revelation comes from city data that the Bloomberg administration refused to reveal for several years.

Of nearly 40,000 NYPD officers and civilians who worked at Ground Zero and related sites after the 9/11 attacks, 321 reported having cancer to the police force’s medical division or applied for WTC disability benefits. All attribute their failing health to inhaling the toxic dust. That’s an increase from the 297 cases documented by the officers union.

Mayor Bloomberg gave the numbers Friday night to Public Advocate Bill de Blasio (a likely 2013 mayoral candidate who has taken charge of this issue) and the Mount Sinai School of Medicine, which is treating ailing first responders and just completed a study showing cancer rates went up 14 percent among the workers.

De Blasio slammed the city for failing to release the names of those with cancer.

The city has repeatedly said that releasing the names poses a privacy concern, but it is now working with Mount Sinai to gather them.

“For first responders living today with cancer, or living in fear of a diagnosis that could come at any time, this information could mean the difference between life and death,” de Blasio said.
