Cell phones produce "non-ionizing" radiation, which, unlike X - or gamma rays, doesn't damage DNA by stripping away electrons from molecules in cell tissue.
Recent in vitro studies - that is, studies on cultured cell tissue - have focused on whether radiofrequency radiation might interfere with the DNA repair process and cause damaged DNA to accumulate.
The progress of research on labeling of aberrant cell tissue by fluorescent probe or by connecting with biologically active carrier is reviewed.
