“Clear Evidence” of Cancer Risk: NTP Cell Phone Study Results Complete and Reproducible

on by

“The NTP does the best animal bioassays in the world. Their reputation is stellar. So if they are telling us this was positive in this study, that’s a concern.” Dr. Christopher Portier, former Director U.S. CDC

The results of the most comprehensive study of cell phone radiation and cancer by the National Toxicology Program to date are in and they are raising awareness and serious concerns. After 10 years and $25 million spent in funding, this rigorous study found “Clear evidence” of carcinogenicity in malignant tumors of the heart with non-thermal whole body exposure to non-ionizing radiation, in addition to significant increase in malignant gliomas of the brain, DNA damage and cardiomyopathy (heart disease). The well-conducted NTP study is supported by 2 other life-span studies (Chou et al 1992 and Falcioni et al 2018) demonstrating similar findings with long term exposure to cell phone radiation.  https://mdsafetech.org/ntp-study-2016/

Whole Body Exposure Affects Internal Organ Systems

Many physicists have argued this type of radiofrequency radiation cannot cause adverse biological effects.  An NTP  peer review panel of 11 toxicologists and pathologists, however, concluded on March 28, 2018 at Research Triangle Park, North Carolina, that there are significant positive findings for malignant schwannomas of the heart, gliomas of the brain and tumors of the adrenal gland (pheochromocytoma). They also found increases, although not statistically significant, in tumors of other organs including malignant lymphoma, the skin (fibrous histiocytomas and sarcomas), pituitary gland, prostate gland, pancreas, lung and liver compared to sham control groups. In addition, there was evidence of DNA damage in both the rat and mice research. https://ehtrust.org/wp-content/uploads/NTP-DNA-Damage-Abstract-from-Sept-2017-Presentation-.pdf .

Cardiomyopathy: An Aging heart

Another unusual and unexpected finding was a statistically significant increase in cardiomyopathy in male rats, which they stated indicated an aging heart.  “Cardiomyopathy was characterized by degeneration and necrosis of myofibers with a mild inflammatory response of macrophages and lymphocytes with occasional neutrophils.” Page 95 NTP Final Technical Report https://ntp.niehs.nih.gov/ntp/about_ntp/trpanel/2018/march/tr595peerdraft.pdf.  This indicates that as the non-ionizing radiation passes through the body it can target several organ systems along it’s path, causing broad cellular damage.

Dr. Lennart Hardell, a renowned oncologist in Sweden, underscored the importance of the NTP long term study results, showing an increase in schwannomas and gliomas. This NTP study corroborates carefully done epidemiological studies on cell phone use, which found an increase in similar types of brain tumors in humans with long term use of cell phones on the ipsilateral (same) side of the head.

Dr. Ronald Melnick, who led the design of the rodent NTP study on cell phones and cancer, remarked that the incidence of prostate epithelial hyperplasia was increased in all exposure groups indicating the prostate gland should be specified as a target organ for RFR. He also highlighted that the control rats had significantly reduced incidence of neoplasia compared to historical controls as they were housed in, “uniquely designed reverberation chambers which were fully shielded from external electromagnetic fields.” This may be one of the most significant findings indicating a carcinogenic effect of RFR, as the absence of the radio frequency radiation seemed to offer protection from the development of cancer.

Reducing Exposures

This important study, along with the Falconi research on long term effects and Dr  Li’s prospective Kaiser  study, on miscarriage and everyday EMR exposures adds to the significant weight of evidence of harm from radio frequency microwave radiation. These recent studies are a call to action to reduce not expand wireless networks and consider expanding a safer and more private alternative fiberoptic broadband networks.
