Increased risk of prostate cancer, thyroid cancer and multiple myeloma in 9-11 rescue and recovery workers


Among rescue and recovery workers exposed to the dust, debris and fumes following the World Trade Center terrorist attack, there was an increased incidence of prostate and thyroid cancers and multiple myeloma, although it is not clear how big a factor medical screening and non-WTC risk factors contributed to these increases, according to a study in the Dec. 19 issue of JAMA. The authors did not find a statistically significant increased incidence for all cancer sites combined, and note that the findings on the three cancers that did increase should be viewed with caution for several reasons, including that they were based on a small number of cancers, multiple comparisons and a relatively short follow-up time.
