This major 2-year rat study found no cancer increase from daily cell phone radiation exposure, even at levels 8 times higher than phone safety limits.

Plain English Summary

Summary written for general audiences

Researchers exposed 1,170 rats to cell phone radiation (GSM and DCS signals) for 2 hours daily, 5 days a week for up to 2 years to test whether this exposure causes cancer. They found no increase in tumors or cancer rates compared to unexposed control rats, even at the highest radiation levels tested. This large, long-term study suggests that chronic exposure to these specific wireless signals at the tested levels does not increase cancer risk in rats.
