Abstract

Overview

This study investigates the impact of funding sources on the conclusions of studies related to the risk of cancer from exposure to electromagnetic fields, specifically those at extremely low frequencies (50 to 60 Hz).

Findings

• Childhood Cancer: Meta-analyses show significant associations between magnetic field exposure and an increased risk of childhood leukemia. Government or independent studies generally report a significant risk, whereas industry-backed studies often do not.
• Adult Cancers: There is substantial evidence linking excessive exposure to magnetic fields with higher risks of leukemia, breast cancer, and brain cancer in adults. Other cancer types show suggestive associations.
• Parental Exposure: Evidence suggests that prenatal exposure to magnetic fields through parents might increase the risk of leukemia and brain cancer in offspring.

Conclusion

Accounting for the bias in source of funding reveals a consistent link between electromagnetic fields and an increase in cancer risk. Both adults and children show susceptibility, with stronger evidence for certain cancers such as leukemia, brain, and breast cancer.
