Heavy mobile phone users showed increased cellular abnormalities in mouth tissue, suggesting potential gene amplification problems despite normal DNA damage markers.

Plain English Summary

Summary written for general audiences

Brazilian researchers examined cells from the mouths of 45 mobile phone users to look for DNA damage and cell death markers. They found no differences in most cellular damage markers between light, moderate, and heavy phone users (more than 5 hours per week). However, heavy users showed significantly more 'broken egg' structures in their cells, which may indicate gene amplification problems.

Study Details

Transmission and reception of mobile telephony signals take place through electromagnetic wave radiation, or electromagnetic radiofrequency fields, between the mobile terminal and the radio base station. Based on reports in the literature on adverse effects from exposure to this type of radiation, the objective of this study was to evaluate the genotoxic and cytotoxic potential of such exposure, by means of the micronucleus test on exfoliated cells from the oral epithelium.

The sample included 45 individuals distributed in 3 groups according to the amount of time in hours ...

The occurrences of micronuclei and degenerative nuclear abnormalities did not differ between the gro...
