View Original AbstractLong-term cell phone radiation exposure showed no increased cancer risk in cancer-prone mice, contradicting earlier findings.
Plain English Summary
Researchers exposed cancer-prone mice to cell phone radiation (898.4 MHz) for up to 2 years at various intensities to see if it increased lymphoma rates. They found no significant increase in cancer incidence at any exposure level, even in mice genetically predisposed to develop lymphomas. This study contradicted an earlier 1997 study that found increased cancer risk from similar radiofrequency exposure.
Why This Matters
This study represents a significant attempt to replicate controversial findings from Repacholi's 1997 research, which showed increased lymphoma rates in similar cancer-prone mice exposed to 900 MHz radiation. The failure to reproduce those results raises important questions about the reproducibility of EMF cancer research. However, the exposure levels tested (0.25-4.0 W/kg SAR) are considerably higher than typical cell phone use, which averages around 1.6 W/kg maximum SAR. What this means for you is that while this particular study found no cancer link, the broader body of research on EMF and cancer remains mixed, with some studies showing effects and others not. The science demonstrates that we still lack definitive answers about long-term cancer risks from radiofrequency exposure.

The findings showed that long-term exposures of lymphoma-prone mice to 898.4 MHz GSM radiofrequency (RF) radiation at SARs of 0.25, 1.0, 2.0 and 4.0 W/kg had no significant effects when compared to sham-irradiated animals.
