fdny logo Studies continue to show increased cancer risk for 9/11 first respondersResearch conducted by the Fire Department of the City of (FDNY), and published by The Lancet, provides evidence of an increased risk for cancers of all types among who were first responders on 9/11. The findings were released on Sept. 3, as American began to reflect on the 10th anniversary of the terrorist attacks. This particular study focused on rescue workers who responded to the attack on the World Trade Center in City.

According to The Lancet, “Respiratory illnesses and post-traumatic stress disorder are known to be increased in those who survived the World Trade Center disaster, but data reported in this issue show that 9 years after the attacks, rescue and recovery workers continue to have substantial physical and mental health problems.”

While it is too early yet to find evidence of increased mortality among these workers, the research indicates that “An excess of cases is reported in who survived the disaster..” according to The Lancet.

The study, titled “Early assessment of outcomes in City after the 9/11 attacks: an observational cohort study” was published in Volume 378, Issue 9794 of The Lancet. Researchers studied incidence and its potential association to exposure of City to known and suspected carcinogens at Ground Zero. The study examined the effect of these possible carcinogens on FDNY first responders in the first 7 years after 9/11/01.

According to the report, the study included 9,853 men who were employed as on Jan. 1, 1996. Researchers determined that “on and after 9/11, person-time for 8,927 was classified as WTC-exposed; all person-time before 9/11, and person-time after 9/11 for 926 non-WTC-exposed , was classifed as non-WTC exposed.” Explaining their methods, researchers state in the report, “We estimated the ratio of incidence rates in WTC-exposed to non-exposed , adjusted for age, race and ethnic origin, and secular trends, with the US National Institute Surveillance Epidemiology and End Results (SEER) reference population.”

In its Findings summary, the report concluded that incidence in exposed to toxins at the World Trade Center was about 1 in 10, while incidence in the general male population in the U.S. was about 1 in 19. This incidence among the non-WTC-exposed also was about 1 in 19. This leads researchers to believe there is a “modest excess of cases in the WTC-exposed” group.

However, researchers also caution that there has been a relatively short time period since the events of 9/11 and the exposures, while many cancers, such as , may have long developmental periods. They recommend continued follow-up including screenings and prevention strategies.

  1. Mesothelioma

    Due to this, large numbers of rescue workers as well as people living or working in the close by areas were exposed to this deadly mineral when they inhaled it. It took a long period of time for asbestos dust and particles to settle and by then numerous people had already inhaled it.

  2. Order Taking Service

    That is shocking news because these firefighter take risk to save the lives of people in the twin towers. Government should take action to fight against this dangerous disease “Cancer” in firefighters.
