Even at exposure levels 1000 times higher than safety limits, 94 GHz radiation showed no cancer-promoting effects in mice.

Plain English Summary

Summary written for general audiences

Researchers exposed mice to 94 GHz millimeter wave radiation (the same frequency range used in some 5G networks) to see if it would promote skin cancer development. Even at very high power levels - 1000 times stronger than typical exposure limits - the radiation showed no effect on tumor formation or growth. This suggests that millimeter wave radiation at these frequencies does not act as a cancer promoter in skin tissue.

Study Details

In this study we investigated whether a single (1.0 W/cm(2) for 10 s) or repeated (2 exposures/week for 12 weeks, 333 mW/cm(2) for 10 s) exposure to 94 GHz RFR serves as a promoter or co-promoter in the 7,12-dimethylbenz[a]anthracene (DMBA)-induced SENCAR mouse model of skin carcinogenesis.

Neither paradigm of MMW exposure significantly affected papilloma development, as evidenced by a lac...

Therefore, we conclude that exposure to 94 GHz RFR under these conditions does not promote or co-promote papilloma development in this animal model of skin carcinogenesis.

Quick Questions About This Study

Research on 94 GHz millimeter waves (used in some 5G networks) found no evidence of skin cancer promotion in animal studies. Even at exposure levels 1000 times higher than safety limits, the radiation showed no effect on tumor formation or growth in mice.
A 2001 study found that 94 GHz radiation exposure did not promote skin cancer development in mice, even at extremely high power levels. The research suggests this frequency range does not act as a cancer promoter in skin tissue.
Studies on 94 GHz millimeter wave radiation show no significant effect on cancer development. Research found no increase in tumor incidence or growth when animals were exposed to these frequencies at very high power levels.
Current research indicates minimal cancer risk from 94 GHz waves. Animal studies found no evidence that this frequency promotes skin cancer, even when exposure levels were 1000 times stronger than typical safety limits allow.
Research shows 94 GHz exposure does not impact tumor growth or development. In controlled animal studies, millimeter wave radiation at this frequency showed no effect on papilloma formation, incidence, or multiplicity compared to unexposed groups.
