Of the 738 studies in our Cancer & Tumors collection, 584 identified effects ranging from DNA damage and increased cancer cell proliferation to disrupted cellular repair mechanisms.
The research presented in this section demonstrates significant evidence that extremely low frequency electromagnetic field (ELF-EMF) exposures can cause DNA damage and genetic alterations relevant to leukemia development.

Heat as Cancer Therapy
Bull JM, Chretien PB · 1976
Microwave Heating of Malignant Mouse Tumors and Tissue Equivalent Phantom Systems
J. Eugene Robinson, Duncan McCulloch, Edgar A. Edelsack · 1976
Researchers exposed mammary tumors on mice to 2450 MHz microwaves at up to 200 watts in a free-field setup. Microwave heating alone from room temperature was marginal and produced unacceptably high thermal non-uniformities. Adding warm air to preheat tumors to body core temperature allowed hyperthermic temperatures of 40°C and 43°C with only 30 watts of microwave power. However, the maximum temperature deviation within tumors remained about 1.5°C, exceeding the desired uniformity of less than 0.25°C.
Responses of the Mouse to Microwave Radiation During Estrous Cycle and Pregnancy
Roberts Rugh, Edward I. Ginns, Henry S. Ho, William M. Leach · 1975
Researchers exposed individual CF1 mice to 2450 MHz microwave radiation in a waveguide with controlled temperature, humidity, and air flow. Female mice in estrus had a lower average lethal absorbed dose (10.65 cal/g) than those in diestrus (11.50 cal/g). Pregnant mice exposed on gestation day 8 showed teratogenic effects including exencephalies, hemorrhages, resorptions, stunting, and fetal death at absorbed doses of 3 to 8 cal/g, and the response was not all-or-none. As absorbed dose increased, the probability of at least one exencephaly per litter increased, but the relationship was not linear and varied widely among litters. A total of 1096 mice were exposed and monitored individually.

Microwave Characteristics of Human Tumor Cells
Michael E. Stamm et al. · 1974
Researchers cultured fresh tumor specimens and normal control tissues from cancer patients and measured microwave transmission at 76-86 GHz using an interferometer that subtracted normal cell spectra from tumor cell spectra. Tumor cells of the same histologic type from different patients produced similar differential spectra, while different tumor types (sarcomas, melanomas, carcinomas) showed distinct spectral responses. The height of peaks in the differential spectrum indicated the relative proportion of tumor versus normal cells in the sample, with mostly normal tumor samples yielding near-null responses. Measurements were performed blind, with histopathologic identity determined only after microwave data were reduced and correlated.

ENHANCEMENT OF CANCER CHEMOTHERAPY BY SELECTIVE ELECTROMAGNETIC HEATING OF TUMORS
H. A. Ecker, C. P. Burns, R. L. Magin, V. P. Popovic · 1971
In the differential hypothermia technique, the whole animal was cooled to 40-50°F and electromagnetic radiation heated the tumor to approximately 98°F. Cooled healthy tissues utilized very little of the anticancer drug while the warm tumor with high metabolic rate was affected to a much higher degree. Mice with spontaneous tumors treated with 5-fluorouracil and differential hypothermia showed significant tumor regression after several hours. Rats with chemically induced tumors showed tumor regression in all cases after differential hypothermia and chemotherapy. A technique using 3-30 MHz radiation with ferrite or magnetic stainless steel doping was developed for heating deep tumors such as in the brain.

Bernice H. Cohen, Abraham M. Lilienfeld · 1970
Mothers of children with mongolism reported significantly less often having no radiation exposure (50% vs 59.9%) than control mothers. The estimated relative risk for maternal radiation exposure was 1.5, corresponding to an attributable risk of 17%. Fathers of mongol children more often reported radar exposure (8.75%) than control fathers (3.3%), a difference of borderline significance.

FAQs: EMF & Cancer & Tumors
Nearly four out of five studies examining the relationship between electromagnetic field (EMF) exposure and cancer risk have documented measurable effects. Out of 738 total studies on this topic, 584 show evidence of cancer-related harm-a 79% concordance rate that reflects a substantial body of scientific concern. This isn't a marginal or disputed finding relegated to fringe research.
The SYB Research Database includes 572 peer-reviewed studies examining the relationship between electromagnetic field exposure and cancer & tumors. These studies have been conducted by researchers worldwide and published in scientific journals. The research spans multiple decades and includes various types of EMF sources including cell phones, WiFi, power lines, and other common sources of electromagnetic radiation.
75% of the 572 studies examining cancer & tumors found measurable biological effects from EMF exposure. This means that 431 studies documented observable changes in biological systems when exposed to electromagnetic fields. The remaining 25% either found no significant effects or had inconclusive results, which is typical in scientific research where study design and exposure parameters vary.
