Following the attacks on the World Trade Center, 50,000 workers were involved in rescue and recovery, with many of them caught directly in the dust cloud from the collapsing towers. From then until cleanup of the site ended in June 2002, workers were potentially exposed to an array of toxins later shown to cause adverse health effects, including cancer.
This study examined cancer incidence in responders including law enforcement, construction, and telecommunications workers, and found an increased overall cancer incidence, with the greatest elevation in thyroid cancer. It is the first to show an increase in leukemia, which is known to occur after exposure to occupational carcinogens, including benzene fuel and other sources that existed at the World Trade Center site, in some cases at low levels of exposure and with a latency of several years from exposure.
Researchers - Length - Time - Responders - Recovery
Researchers also found that neither the length of time that first responders and recovery workers worked on the World Trade Center site, nor the intensity of their exposure, had any bearing on the development of the elevated cancers. However, some risk factors -- such as responders' age on September 11, their gender, and whether...
