Effects of radiofrequency electromagnetic field exposure on cancer in laboratory animal studies, a systematic review
This systematic review evaluated RF EMF exposure and cancer outcomes in experimental animals, including chronic cancer bioassays and tumor-promotion designs. Across 52 included studies, the authors report high certainty of evidence for increased malignant heart schwannomas and gliomas in male rats, and moderate certainty for increased risks of several other tumor types. Many other organ systems showed no or minimal evidence of carcinogenic effects, and the authors note challenges in translating animal findings to human risk assessment due to exposure and mechanistic uncertainties.
Key points
- The review included 52 animal studies, including 20 chronic cancer bioassays.
- Due to heterogeneity across studies, the authors did not perform a quantitative meta-analysis and instead used narrative synthesis.
- High certainty of evidence was reported for increased malignant heart schwannomas in male rats exposed to RF EMF.
- High certainty of evidence was reported for increased glial cell-derived brain neoplasms (gliomas) in male rats exposed to RF EMF.
- Moderate certainty of evidence was reported for increased risks of lymphoma, pheochromocytoma, hepatoblastomas, and lung neoplasms.
- Most studies reported no or minimal evidence of cancer effects in several other organ systems.
- The authors state that translating animal results to human risk assessment is complex due to uncertainties in exposure metrics and carcinogenic mechanisms.
