Cancer will not be covered by the Zadroga Act, according to a new report released today by the federal government.

Dr. John Howard, in a report released today by the National Institute for Occupational Safety and Health, said that there is “insufficient evidence” to add cancer to the list of diseases for which 9/11 first responders are covered to be reimbursed for treatment.

The report comes a blow to the estimated “hundreds, if not thousands” of responders suffering from cancer, said John Feal, who runs the FealGood Foundation to help sick 9/11 responders.

“This report is going to cause a lot of pain and a lot of upset people,” Feal told Metro.
