title: Risk for leukaemia and brain and breast cancer among Danish utility workers: a second follow-up.
abstract: OBJECTIVE
  To update a study of risks for leukaemia, brain cancer and breast cancer in a Danish nationwide, population-based cohort of utility employees.
  
  
  METHODS
  A multivariate statistical model including information on age, duration of employment, date of first employment and level of occupational exposure to electromagnetic fields was applied.
  
  
  RESULTS
  No increased risk for these cancers was seen among 28,224 subjects with more than 3 months of employment in whom cancer had not been diagnosed before first employment.
  
  
  CONCLUSIONS
  The results do not support the hypothesis of an association between occupational exposure to magnetic fields in the electric utility industry and risks for leukaemia, brain cancer and breast cancer.
