A combined population of 30,000 firefighters from three large cities had higher rates of several types of cancers, and of all cancers combined, than the U.S. population as a whole, researchers from the National Institute for Occupational Safety and Health (NIOSH) and colleagues found in a new study.
The new findings are generally consistent with the results of several previous, smaller studies. Because the new study had a larger study population followed for a longer period of time, the results strengthen the scientific evidence for a relation between firefighting and cancer, the researchers said.
The findings were reported in an article posted on-line on Oct. 14, 2013, by the peer-reviewed journal Occupational and Environmental Medicine. The article is available online at http://oem.bmj.com/content/early/2013/10/14/oemed-2013-101662.full .
