Abstract

An apparent cancer cluster at a police detachment in a coastal British Columbia community was investigated. Police personnel suspected that the detachment building may have been a factor. Police personnel (20 current and 154 previous employees) associated with the detachment since 1963, the date of occupancy, were traced. After all 174 cases were contacted directly, or next of kin in case of death, a total of 16 cases of cancer or suspected cancers were reported. Of these 16, eight cases of cancer were confirmed through a cancer registry. Cancers included testicular, cervical, colon, skin (including melanoma), leukemias and lymphomas with an age range of diagnosis between 22 and 44 years. There was no evidence for an underlying event, factor or condition in the police building that could be attributed to the observed cancer cases. A possible association between these cancers and the use of police traffic radar is discussed.

Main findings

Among 174 traced personnel, 16 cancers or suspected cancers were reported; 8 cancers were confirmed through a cancer registry. The investigation found no evidence of an event, factor, or condition in the police building that could be attributed to the observed cancer cases; a possible association with police traffic radar use is discussed.

Outcomes measured

  • Cancer (reported and registry-confirmed)
  • Testicular cancer
  • Cervical cancer
  • Colon cancer
  • Skin cancer (including melanoma)
  • Leukemias
  • Lymphomas

Limitations

  • Cancer ascertainment included self-report/suspected cases (only 8/16 confirmed via cancer registry)
  • No exposure metrics (e.g., radar frequency, intensity, duration) reported in abstract
  • No comparison group or expected cancer rates described in abstract
  • Small number of confirmed cases
