Abstract

Overview

This systematic review and meta-analysis investigate the links between extremely low-frequency magnetic fields (ELF-MFs) and the risk of childhood cancer. These types of magnetic fields have been classified as a possible carcinogenic factor.

Methods

  • Assessment involved data from three databases collected in January 2020.
  • A meta-analysis calculated the association between ELF-MF exposure and childhood cancer rates.

Findings

  • The study examined a total of 33 studies involving 186,223 participants.
  • Exposure to differing levels of ELF-MFs (0.2-, 0.3-, and 0.4-μT) led to an increased odds of childhood leukemia and other cancers, with a notable dose-response effect seen in higher exposure levels.

Conclusion

There is a significant association between exposure to ELF-MFs and an increased risk of childhood leukemia, with evidence supporting a possible dose-response effect. It is crucial to continually assess this potential health risk through robust epidemiological data.
