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.
Conclusion:
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.
