A new report from the city's Health Department finds that September 11th survivors are more at risk for serious health problems than initially expected.

The report says September 11th first responders are 11 percent more likely to have cancer than the average New York State resident. 

Civilians who were near the World Trade Center that day are 8 percent more likely to have cancer.

Workers who were evacuated from the towers are 30 percent more likely to suffer post-traumatic stress disorder, and workers with September 11th health-related issues are more inclined to retire early or lose their jobs. 

The Health Department conducted the study between 2007 and 2011.
