RF Fields Promote Tumors Below Human Exposure Limits

The results are “worrying,” say the authors of a newly published study [1] dealing with the exposure of mice to radiofrequency (RF) radiation fields.

According to Professor Alexander Lerchl, who conducted the new investigative study together with his colleagues from Jacobs University and also the University of Wuppertal in Germany, Our results show that electromagnetic fields obviously enhance the growth of tumors.”

Graphical Abstract for RF Article

Article/ Study Highlights (as summarized by the authors)

  • Tumor-promoting effects of RF-EMF exposed mice have been [previously] reported in 2010.
  • We have replicated the study with higher numbers of mice per group.
  • We could fully confirm the previous results, thus the effects are reproducible.
  • Apparently, no clear dose-response relationship is evident.
  • We hypothesize that metabolic changes are responsible for the effects observed.

Article Abstract 

The vast majority of in vitro and in vivo studies [previously] did not find [carcinogenic] effects of exposure to electromagnetic fields (RF-EMF), i.e. emitted by mobile phones and base stations. … Published results from a pilot study with carcinogen-treated mice, however, suggested tumor-promoting effects of RF-EMF (Tillmann et al., 2010).

We have performed a replication study using higher numbers of animals per group and including two additional exposure levels (0 (sham), 0.04, 0.4 and 2 W/kg SAR).

We could confirm and extend the originally reported findings.

Numbers of tumors of the lungs and livers in exposed animals were significantly higher than in sham-exposed controls.  In addition, lymphomas were also found to be significantly elevated by exposure.  A clear dose-response effect is absent. We hypothesize that these tumor-promoting effects may be caused by metabolic changes due to exposure.  Since many of the tumor-promoting effects in our study were seen at low to moderate exposure levels (0.04 and 0.4 W/kg SAR), thus well below exposure limits for the users of mobile phones, further studies are warranted to investigate the underlying mechanisms.

Our findings may help to understand the repeatedly reported increased incidences of brain tumors in heavy users of mobile phones.

Selected Quotations from Article

“Our study confirms and extends the previously published observations of tumor-promoting effects of life-long RF-EMF exposure.  The numbers of both adenomas and carcinomas were significantly increased in the lungs, and carcinomas were significantly elevated in the livers of RF-EMF exposed animals …”

“The fact that both studies [in 2010 and in the current study] found basically the same tumor-promoting effects at levels below the accepted (and in most countries legally defined) exposure limits for humans is worrying.”

“Although animal experiments are generally not easily transferable to the situation in humans, the findings are a very clear indication that – in principal – tumor-promoting effects of life-long RFEMF exposure may occur at levels supposedly too low to cause thermal effects.”


It should be kept in mind that this study did not specifically look for tumor production solely based upon exposure to RF radiation.  In fact female mice were injected with a known carcinogen, ethylnitrosourea (ENU); the offspring were then observed for tumor production based upon being exposed to differing levels of RF fields throughout their lives to determine if the RF exposure affected tumor production, presumably also related to the presence of the ENU agent.

It is extremely noteworthy that the results of this new study demonstrated:

  • A replication of the findings of a prior study;
  • Tumor production is evident at a level approximately 50 times less than most national exposure standards;
  • No clear dose response effect was noted, i.e., exposure at low levels was just as likely to produce tumors as at higher levels.

It is hypothesized by the authors of the new study that RF exposure may have been responsible for changing the metabolism of the exposed animals in a way that in turn resulted in a higher uptake by the fetuses of the administered carcinogen.

The new study not only supports the 2011 declaration by the International Agency for Research on Cancer (IARC) that RF radiation fields are “possibly carcinogenic” but also demonstrates how RF fields may promote the effects of other carcinogenic agents in the production of cancer.

Higher tumor rates through exposure to electromagnetic fields

Electromagnetic fields stimulate the growth of tumors in mice.  This is the result of a new study by researchers from Jacobs University, which was commissioned by the Federal Office for Radiation Protection, and published today.

The findings do not only confirm a previous pilot study undertaken by the Fraunhofer Institute ITEM in 2010, but expand on the knowledge in two important aspects.

Lerchl PhotoIn a study with mice, Alexander Lerchl, Professor of Biology at Jacobs University, and his team could verify that carcinogen-induced tumor rates were significantly higher when the animals were exposed to electromagnetic fields such as those emitted from mobile phones.

“The effects on liver and lung tumors, as reported by ITEM in 2010, were fully confirmed,” says Prof. Lerchl, who conducted the investigation together with colleagues from Jacobs University and from the University of Wuppertal.  “In addition we found a significantly elevated rate of lymphoma due to exposure,” the scientist explains.  Furthermore, some of the effects were seen at levels below the exposure limits for the general population.

Alexander Lerchl, however, does not interpret the new data as being a proof for cancer induction through the use of mobile phones.  “Our results show that electromagnetic fields obviously enhance the growth of tumors.  The assumption that they can cause cancer has not been proven so far,” Prof. Lerchl emphasizes.  The biologist has published a large number of studies on the topic.

Additional research is necessary to clarify the reasons for the latest results findings. “We can clearly demonstrate the effects.  Now new studies must aim at explaining the underlying mechanisms”, Prof. Lerchl concludes.

1 Response to RF Fields Promote Tumors Below Human Exposure Limits

  1. Sonia R. says:

    You can rely on the results of studies using mice and rats. Their bio-systems are the same as ours. Research ethics supposedly precludes using humans as subjects and exposing them to known dangers to collect data. Ha!
    This whole wireless mess is nothing but a global experiment where the perpetrators use their power and money to get fat by killing off the population, because ultimately one day (about 60 yrs. from now) from using wireless devices that break our DNA strands and disrupt cell production and distribution up close and personal, humans will no longer be able to procreate. I’ve seen this in my profession. Thirty-five years ago infertility in just women was 1 in 25. Now it is 1 in 5 PLUS male infertility is increasing at an alarming rate. Why do you think that is? Think about where most people keep their cells. In their pockets, right next to their ovaries and gonads. Deadly brain tumors. Why so many? Oh, of course. You put your cell to your ear when you use it! Cell towers…are they dangerous? You betcha! San Diego State University is identified as a brain cancer cluster. Most of the student and teacher profiles showed those who died worked long hours next to a cell tower with a ground function emanating RF radiation right next to where both teachers and students spent a lot of time. This generation grew up with cell phones and wireless personal technology, and we have seen a tremendous increase in childhood leukemia and cancer. Coincidence? Nah! They have WiFi over their heads all day, personal devices in school at their desks, multiple personal devices at home, and smart meters, which operate in the same relative frequency range as cell towers, attached to their homes. Cell towers, which are commercial ventures are being routinely installed in residential communities. Towers are not supposed to be installed in dense population areas, so why are they? They are, because YOU, the public are wireless addicts; but this is an addiction for which there is no treatment. RF radiation triggers the stress response repeatedly which ultimately causes disease and/or cancer.
    Not to worry though, because the nanotechnologists plan for us to be half robotic by 2028 and fully robotic by 2050 or thereabouts. No more humans! We’ll all be droids! Glad I won’t be around, BUT our children and grandchildren will be…or will they?
