Study examines cancer rates among World Trade Center-exposed firefighters

(Wiley) Researchers found no overall increase in cancer risk among World Trade Center (WTC)-exposed firefighters following the 9/11 attacks compared with other firefighters from several US cities. They noted a nearly 4-fold increase in the rate in thyroid cancer, but this increased risk was not significant after controlling for possible biases related to cancer screening. (WTC-exposed firefighters have access to health care and routine health monitoring exams even after retirement.)
