Elevated risk of leukemia among 9/11 responders, study suggests

There's now evidence to suggest that responders at the World Trade Center on 9/11 may have an elevated risk of leukemia. These responders have previously been diagnosed with other cancers including mesothelioma and thyroid cancer. And the new study, which included data from nearly 29,000 responders, 999 of whom developed cancer, found that the overall incidence of leukemia was 41% higher than in the general population. In addition, they were more than twice as likely to develop thyroid cancer, and had a 25% higher rate of prostate cancer. Some of these cancers, such as thyroid, emerge long after exposure to harmful substances, and the authors suggest continued monitoring of WTC responders for cancers that may not yet have been observed in this population.
