Cancer Rate for Ground Zero Cops 50 Percent Higher Than Pre-9/11

NYPD cops who worked at Ground Zero after 9/11 had 50 percent more cancer diagnoses than officers did in the years before the terror attacks, a long-awaited study has found.

The NYPD’s 20-year study — the largest ever of cancer among police officers — was distributed internally by the department’s chief surgeon Thursday and obtained exclusively by The Post.

Researchers scrutinized the medical records of nearly 40,000 cops who were on the job on 9/11 and tracked their cancer rates through 2014. Post-9/11 retirees’ rates were also tracked.

The findings showed 859 cops were diagnosed with cancer, with 11 having more than one case for a total of 870 diagnoses.
