Researchers developed a new magnetic device that uses spinning oscillating magnetic fields to selectively kill aggressive brain cancer cells while leaving healthy brain cells unharmed. The device works by damaging the energy-producing parts of cancer cells, causing them to die through a natural cell death process. This represents a potentially safer approach to treating deadly brain cancers like glioblastoma.

Korean researchers exposed male rats to CDMA-modulated 900 MHz radiofrequency radiation at 4 W/kg (the international safety guideline level) for nearly their entire lifespans. They found no increased cancer rates, no genetic damage, and no effects on heart, brain, or adrenal glands. This was part of a coordinated study with Japan to verify earlier National Toxicology Program findings.

Iranian researchers studied 226 women to examine whether mobile phone use increases breast cancer risk. They found women who talked on phones for more than 60 minutes daily had 3.5 times higher odds of confirmed breast cancer compared to those using phones less than 10 minutes daily. The study also included a 'suspected' group of women advised to get mammograms, who showed even higher associations with phone use.
Mevissen et al · 2025
This comprehensive 2025 review analyzed 52 animal studies to evaluate whether radiofrequency electromagnetic field exposure causes cancer. Researchers found high-certainty evidence for increased brain tumors (gliomas) and heart tumors (schwannomas) in male rats, the same tumor types previously linked to cell phone use in humans. The findings strengthen concerns about RF-EMF carcinogenicity that led to its classification as a possible human carcinogen in 2011.

This study investigated whether intermittent versus continuous exposure to 40 Hz, 10mT extremely low frequency magnetic fields (ELF-MF) could improve cognitive and neurological outcomes in adult and aged Alzheimer's disease mice. The researchers found that intermittent ELF-MF stimulation was more effective in adult AD mice for improving spatial working memory and enhancing theta/gamma band neural oscillations in the hippocampus, while continuous stimulation showed better results in aged mice, and ELF-MF exposure reduced abnormal accumulation of amyloid-beta and dynamin-related protein markers.

Researchers exposed bladder cancer cells (HT-1197) to pulsed electromagnetic field (PEMF) therapy for one hour daily over five days. The treated cancer cells grew significantly slower than untreated cells and showed major changes in gene expression patterns. This suggests PEMF therapy might offer a less invasive treatment approach for bladder cancer patients.

Researchers exposed prostate cancer cells to extremely low-frequency pulsed electromagnetic fields at 22.6 and 35 mT intensities. The treatment killed cancer cells and activated genes that suppress tumors while reducing genes that promote cancer growth. This suggests EMF therapy could potentially help treat prostate cancer with fewer side effects than traditional treatments.

Korean researchers analyzed 24 studies involving cell phone use and brain tumors, finding that people who used phones on the same side of their head where tumors developed had 40% higher odds of brain cancer. The risk increased with longer use, reaching 59% higher odds for those with over 896 hours of cumulative phone time.

Researchers exposed triple negative breast cancer cells to extremely low frequency electromagnetic fields (1 Hz, 100 mT) for 2 hours daily over 5 days. The EMF exposure significantly reduced cancer cell migration and invasion while increasing E-cadherin expression and decreasing N-cadherin expression, essentially reversing the molecular changes that make cancer cells more invasive. This suggests specific EMF parameters might help prevent breast cancer metastasis, the primary cause of cancer deaths.

Researchers exposed Schwann cells (the protective coating around nerve cells) to electromagnetic fields at 0.1 Tesla and 50 Hz for just 10 minutes. The exposure triggered epigenetic changes through DNA methylation and histone deacetylation, along with oxidative stress, pushing the cells toward a less healthy state. These cellular changes could explain how EMF exposure might contribute to schwannoma tumor development.

Researchers combined silver nanoparticles with extremely low frequency electromagnetic fields (50 mT for 30 minutes) to attack human laryngeal cancer cells. The combination increased cancer cell death by 6-fold compared to nanoparticles alone. This suggests EMF can enhance certain medical treatments, though the high field strength used far exceeds typical environmental exposure.

Researchers exposed breast cancer cells to power line frequency magnetic fields (50 Hz at 1 milliTesla for 4 hours) and found the fields made cancer cells more aggressive. The exposed cancer cells grew faster, developed more invasive structures, and showed increased ability to migrate and invade surrounding tissue.

Italian researchers studied 182 children with leukemia and 726 healthy controls to see if living near electrical transformer stations increases cancer risk. They found no overall increased risk, but children aged 5 and older showed some elevated risk when living within 15-25 meters of transformers. The study was limited by small numbers of children actually living that close to transformer stations.

This molecular dynamics simulation study investigated how terahertz waves affect the structure of amyloid-beta (Aβ42) peptides at different aggregation states. The researchers found that terahertz waves at 42.55 THz enhanced structural interactions in Aβ42 monomers and dimers by resonating with specific molecular vibration modes, increasing β-sheet content and binding energy between monomers, while also mildly stabilizing tetrameric protofibril structures.

This study examined whether long-term exposure to radiofrequency electromagnetic fields (1950 MHz, 5 W/kg for 6 months) could reduce cognitive dysfunction in 5×FAD mice with Alzheimer's disease by regulating microglial function. The researchers found that RF-EMF exposure ameliorated cognitive impairment and amyloid-β deposition while reducing microglial activation markers and genes related to microgliosis and pro-inflammatory responses, with effects similar to those of a CSF1R inhibitor.

Researchers exposed pregnant rats to continuous 900 MHz GSM cell phone radiation (24 hours daily) and examined oxidative stress markers in developing fetal livers at different stages. The study found increased cellular damage and decreased antioxidant defenses in fetal liver tissue, particularly at mid-gestation (15.5 days), suggesting developing embryos face specific vulnerability windows during prenatal EMF exposure. This matters because it demonstrates that continuous wireless radiation exposure during pregnancy can affect fetal organ development.

Researchers exposed mice to a 50 Hz electric field at 10 kV/m and found it consistently reduced stress hormone levels (glucocorticoids) caused by repeated immobilization stress. The stress-reducing effect worked regardless of how many times mice experienced stress or which way the electrodes were oriented, and appeared strongest when the head remained exposed to the field. This suggests extremely low frequency electric fields may have reproducible biological effects on stress response systems.

Researchers tested extremely low frequency electromagnetic fields (ELF-EMF) and silver nanoparticles against bacteria and breast cancer cells. The combination achieved 100% bacterial kill rates and triggered cancer cell death through programmed cell destruction. The study suggests these agents work by creating oxidative stress that damages harmful cells while potentially sparing healthy ones.

Researchers exposed normal and gastric cancer cells to extremely low frequency magnetic fields at different intensities for 18 hours. They found that specific field strengths (0.25 and 0.5 millitesla) reduced cancer cell viability while boosting normal cell health, and decreased expression of genes linked to tumor growth and spread. This suggests certain EMF exposures might have therapeutic potential against gastric cancer.

Researchers tested whether static magnetic fields combined with natural compounds (caffeic and chlorogenic acid) could kill melanoma cancer cells. They found that both the magnetic field and the plant compounds triggered cell death, with caffeic acid being more effective. This suggests magnetic fields might enhance natural cancer treatments.

Researchers exposed human melanoma cells to power line frequency magnetic fields (50 Hz) for 96 hours and found it significantly reduced the activity of certain viral genes (HERVs) that are linked to cancer development. The study suggests this type of EMF exposure might have therapeutic potential for treating melanoma by suppressing these harmful viral elements.

This study exposed mouse Balb/c-3T3 cells to 1800 MHz radiofrequency electromagnetic radiation for 40-60 days and observed signs of malignant transformation, including increased cell proliferation, migration, visible foci formation, and tumor development when transplanted into SCID mice. The researchers identified lipid metabolism and the mevalonate pathway as key biological processes involved in the observed cellular changes.
Hardell & Carlberg · 2021
This 2021 analysis by Hardell and Carlberg examines historical patterns of delayed cancer prevention, focusing on radiofrequency radiation from wireless devices. The researchers found increasing brain tumor rates in Sweden, particularly among 20-39 year olds, coinciding with widespread wireless phone adoption. They argue that current safety standards ignore non-thermal biological effects and call for proper health evaluation before 5G deployment.
