Abstract

Peculiar Effects of Electromagnetic Millimeter Waves on Tumor Development in BALB/c Mice Bantysh BB, Krylov AY, Subbotina TI, Khadartsev AA, Ivanov DV, Yashin AA. Peculiar Effects of Electromagnetic Millimeter Waves on Tumor Development in BALB/c Mice. Bull Exp Biol Med. 2018 Sep;165(5):692-694. doi: 10.1007/s10517-018-4243-2. Abstract The study examined the effects of millimeter electromagnetic waves at a frequency of 130 GHz corresponding to the molecular absorption and radiation spectra of NO and O2 with the total exposition time of 6 h on tumor morphogenesis in 3- and 6-month-old tumor-prone BALB/c mice of both sexes. In experimental mice exposed to electromagnetic radiation, the development of cancer process was slowed down throughout the observation period; moreover, no macroscopic signs of the tumors were revealed. However, in contrast to control mice, experimental animals demonstrated the formation of pathological reactions reflected by hepatic biochemical indices accompanied by the development of dystrophic and microcirculatory alterations in the liver tissue. ncbi.nlm.nih.gov

Main findings

In mice exposed to 130 GHz millimeter waves for a total of 6 h, the cancer process was reported to be slowed throughout the observation period and no macroscopic signs of tumors were observed. In contrast to controls, exposed animals showed pathological reactions reflected by hepatic biochemical indices with dystrophic and microcirculatory alterations in liver tissue.

Outcomes measured

  • Tumor morphogenesis / tumor development (macroscopic signs)
  • Hepatic biochemical indices
  • Dystrophic alterations in liver tissue
  • Microcirculatory alterations in liver tissue

Limitations

  • Sample size not reported in the provided abstract/metadata
  • Exposure metric (e.g., power density/SAR) not reported
