This review compares two epidemiologic studies of radio-frequency radiation (RFR) exposure among military personnel with overlapping patient groups. One study reported a statistically significant increase in cancer among exposed individuals, while the other did not, which the review attributes to a smaller sample size. The review highlights similar cancer patterns across both studies, including a high proportion of hematolymphoid cancers and earlier onset among exposed individuals, and interprets these similarities as evidence of carcinogenic effects.

This randomized, double-blind, sham-controlled study tested whether CACNA1C rs7304986 genotype modifies sleep EEG responses to 5G RF-EMF exposure. The authors report a genotype-by-exposure interaction, with 3.6 GHz exposure in T/C carriers associated with a faster NREM sleep spindle center frequency versus sham. The abstract also notes longer sleep latency in T/C compared with T/T carriers, and concludes that genetically susceptible groups may show differential physiological responses to 5G RF-EMF.

This animal study exposed fertilized chick eggs to a nearby 1800 MHz mobile phone that was called repeatedly (50 minutes/day) and assessed embryos at days 10 and 15. The exposed group reportedly showed mitochondrial abnormalities in liver, brain, and heart tissues on electron microscopy, along with increased HSP70 in cardiomyocytes and hepatocytes. The authors conclude that radio-frequency electromagnetic waves can induce oxidative stress and mitochondrial damage in developing embryos.

This rat study examined whether pulse-modulated 900 MHz and 1800 MHz RF exposure affects blood-brain barrier permeability using Evans blue dye. The abstract reports increased permeability in male rats at both frequencies (stronger at 1800 MHz) and in female rats at 900 MHz but not at 1800 MHz. The authors suggest mobile-phone-like RF exposure could increase blood-brain barrier permeability under non-thermal conditions, while noting that further mechanistic studies are needed.
