Bernier MO, et al. - Researchers determined the risk of cancer in nuclear medicine (NM) technologists, from the US Radiologic Technologists cohort study, in relation to work history, procedures performed and radioprotection practices. They used multivariable-adjusted models and performed follow-up of mean 7.5 years, during which 960 incident cancers and 425 cancer deaths were reported among the 22 360 technologists who worked with NM procedures. Frequency of performing diagnostic or therapeutic NM procedures and use of radioprotection measures were not found to be consistently related to cancer risk. Moreover, for specific cancers, no clear links were noted. Overall, cancer incidence and mortality were not found to be related to NM work history practices, including greater frequency of procedures performed.
