This study found no evidence that 915 MHz cell phone radiation accelerated existing brain tumors in rats over 2-3 weeks.

Plain English Summary

Summary written for general audiences

Researchers injected brain tumor cells into 154 pairs of rats, then exposed half to 915 MHz microwaves (the frequency used by early cell phones) for 7 hours daily over 2-3 weeks while keeping the other half as controls. They found no difference in tumor growth between exposed and unexposed rats, suggesting that microwave exposure did not accelerate existing brain tumors in this particular experimental setup.

Study Details

The effects of exposure to electromagnetic fields were investigated in a rat brain glioma model.

Some of the exposures correspond to electromagnetic fields used in wireless communication. Microwave...

Thus our results do not support that even an extensive daily exposure to EMF promotes tumour growth when given from the fifth day after the start of tumour growth in the rat brain until the sacrifice of the animal after about 16 days.
