The research has accumulated to where experts state that wireless radiation meets Group 1 classification criteria as a carcinogen.  In fact, some cancer registries are showing a rise in brain cancer.  Here is what we know:
Carlberg M, Hardell L. Decreased Survival of Glioma Patients with Astrocytoma Grade IV (Glioblastoma Multiforme) Associated with Long-Term Use of Mobile and Cordless Phones. International Journal of Environmental Research and Public Health. 2014; 11(10):10790-10805.
  • Use of wireless phones in the >20 years latency group (time since first use) was correlated to decreased survival for  those diagnosed with astrocytoma grade IV . "Due to the relationship with survival the classification of IARC is strengthened and RF-EMF should be regarded as human carcinogen requiring urgent revision of current exposure guidelines."

L. Hardell, M. Carlberg, Cell and cordless phone risk for glioma - Analysis of pooled case-control studies in Sweden, 1997-2003 and 2007-2009, Pathophysiology (2014), Available online 29 October 2014.
  • We concluded that glioma and also acoustic neuroma are caused by RF-EMF emissions from wireless phones, and thus regarded as carcinogenic, under Group 1 according to the IARC classification, indicating that current guidelines for exposure should be urgently revised. This pooled analysis gives further support to that conclusion regarding glioma."

  • International Cancer registries are showing a rise in brain cancer.  Children absorb more microwave radiation, a Class 2 B possible carcinogen than adults.  The fetus is in greater danger than children from exposure to MWR.  The legal exposure limits have remained unchanged for decades.  Cellphone manuals warnings and the 20 cm rule for tablets/laptops violate the “normal operating position” regulation.

  • "However, the positive association was statistically significant in the heaviest users when considering life-long cumulative duration for meningiomas and number of calls for gliomas.  Risks were higher for gliomas, temporal tumours, occupational and urban mobile phone use. These additional data support previous findings concerning a possible association between heavy mobile phone use and brain tumours.”

Davis DL, Kesari S, Soskolne CL, Miller AB, Stein Y. (2013)   Swedish review strengthens grounds for concluding that radiation from cellular and cordless phones is a probable human carcinogen. Pathophysiology. 20(2), 123-9.
  • "If the increased brain cancer risk found in young users in these recent studies does apply at the global level, the gap between supply and demand for oncology services will continue to widen.  Many nations, phone manufacturers, and expert groups advise prevention in light of these concerns by taking the simple precaution of "distance" to minimize exposures to the brain and body.  We note than brain cancer is the proverbial "tip of the iceberg";  the rest of the body is also showing effects other than cancers.”

“This study confirmed previous results of an association between mobile and cordless phone use and malignant brain tumours. These findings provide support for the hypothesis that RF-EMFs play a role both in the initiation and promotion stages of carcinogenesis”.

  • In the multivariate analysis, a significantly increased risk of acoustic neuroma was found with the use of analogue phones.

  • “Ipsilateral use resulted in a higher risk than contralateral for both mobile and cordless phones. OR increased per 100 h cumulative use and per year of latency for mobile phones and cordless phones, though the increase was not statistically significant for cordless phones. The percentage tumour volume increased per year of latency and per 100 h of cumulative use, statistically significant for analogue phones. This study confirmed previous results demonstrating an association between mobile and cordless phone use and acoustic neuroma.”

  • An increased risk was found for glioma and use of mobile or cordless phone. The risk increased with latency time and cumulative use in hours and was highest in subjects with first use before the age of 20.

  • Based on the Hill criteria, glioma and acoustic neuroma should be considered to be caused by RF-EMF emissions from wireless phones and regarded as carcinogenic to humans, classifying it as group 1 according to the IARC classification.  Current guidelines for exposure need to be urgently revised.”

  • “We give an overview of current epidemiological evidence for an increased risk for brain tumours including a meta-analysis of the Hardell group and Interphone results for mobile phone use.  It is concluded that one should be careful using incidence data to dismiss results in analytical epidemiology.  The IARC carcinogenic classification does not seem to have had any significant impact on governments' perceptions of their responsibilities to protect public health from this widespread source of radiation."

  • “The current study found that there is possible evidence linking mobile phone use to an increased risk of tumors from a meta-analysis of low-biased case-control studies.  Prospective cohort studies providing a higher level of evidence are needed”.

  • In conclusion, 900 MHz EMR appears to induce apoptosis effects through oxidative stress and mitochondrial depolarization although incubation of selenium seems to counteract the effects on apoptosis and oxidative stress.

Increased Evidence?

This article gives an overview of the recent studies and statements made by numerous scientists calling for a reclassification of the WHO designation of RF radiation from a 2B possible carcinogen to a 2A probable carcinogen.

Redmayne, M. (2013). New Zealand adolescents' cellphone and cordless phone user-habits: are they at increased risk of brain tumours already?: a cross-sectional study. Environmental Health, 12(5).

  • The fertility literature is inconclusive, but increasingly points towards significant time- and dose-dependent deleterious effects from cellphone exposure on sperm.
  • Genotoxic effects have been demonstrated from "non-thermal" exposures, but not consistently.
  • There is sufficient evidence and expert opinion to warrant an enforced school policy removing cellphones from students during the day.

What do some  of the most respected researchers think of this issue?

Dr Hardell  states the evidence meets Hill criteria to be a carcinogen.  He states that if we do not take precautions we could be taking a massive risk with serious   repercussions.

  • All  independent research shows increased brain cancer (glioma) after ten years of cell phone use (over 30 minutes a day). 
  • People who started their cell use as teens had up to 8 times the cancer risk.
  • Research shows decreased survival in long term cellphone users diagnosed with the most malignant glioma. 
  • Several scientists who served on the World Health Organizations Working Group are now stating the evidence has increased and that precautions are urgently needed to protect the public.
