Roberts Rugh, Edward I. Ginns, Henry S. Ho, William M. Leach · 1975
Researchers exposed 1,096 mice to microwave radiation to study how female reproductive cycles and pregnancy affect radiation sensitivity. They found female mice were more vulnerable during estrus (heat) than other cycle phases, and pregnant mice exposed on day 8 of pregnancy developed birth defects including brain malformations at doses as low as 5 calories per gram of body weight. The study revealed complex, non-linear dose-response relationships that make predicting biological effects difficult.

Michael E. Stamm et al. · 1974
Researchers exposed human cancer cells and normal cells to microwave radiation between 76-86 GHz and found that cancer cells transmitted the microwaves differently than healthy cells. This 1974 study demonstrated that extremely high-frequency microwaves could distinguish between malignant and normal human tissue in laboratory cultures. The findings suggest cancer cells have unique electromagnetic properties that make them respond differently to microwave energy.
