Studie: Using the Hill viewpoints from 1965 for evaluating strengths of evidence of the risk for brain tumors associated with use of mobile and cordless phones

 

Results: The criteria on strength, consistency, specificity, temporality, and biologic gradient for evidence of increased risk for glioma and acoustic neuroma were fulfilled. Additional evidence came from plausibility and analogy based on laboratory studies. Regarding coherence, several studies show increasing incidence of brain tumors, especially in the most exposed area. Support for the experiment came from antioxidants that can alleviate the generation of reactive oxygen species involved in biologic effects, although a direct mechanism for brain tumor carcinogenesis has not been shown. In addition, the finding of no increased risk for brain tumors in subjects using the mobile phone only in a car with an external antenna is supportive evidence. Hill did not consider all the needed nine viewpoints to be essential requirements.

 

Conclusion: 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.

LTE (4G) straling beïnvloedt de hersenactiviteit

 

Een van de eerste studies naar de effecten ten gevolge van een korte blootstelling aan Long Term Evolution (LTE), de vierde generatie mobiele technologie (4G),  werd recent online gepubliceerd in de peer-reviewed wetenschappelijke journal Clinical Neurophysiology (persbericht).

 

De onderzoeksresultaten toonden aan dat de straling  een directe invloed had op de neurale activiteit van het brein en niet alleen in de directe omgeving van de stralingsbron maar ook in de periferie.

 

De nieuwe studie toont hiermee nog maar eens aan dat biologische effecten voorkomen bij korte blootstelling aan gsm-straling onder of gelijk aan de ICNIRP norm.

Casestudies: smartphone in BH dragen leidt tot borstkanker

 

20120430-smartphone-braStudie verschenen in het wetenschappelijke tijdschrift 'Case Reports in Medicine':

 

"Breast cancer occurring in women under the age of 40 is uncommon in the absence of family history or genetic predisposition, and prompts the exploration of other possible exposures or environmental risks.

We report a case series of four young women—ages from 21 to 39—with multifocal invasive breast cancer that raises the concern of a possible association with nonionizing radiation of electromagnetic field exposures from cellular phones. All patients regularly carried their smartphones directly against their breasts in their brassieres for up to 10 hours a day, for several years, and developed tumors in areas of their breasts immediately underlying the phones. All patients had no family history of breast cancer, tested negative for BRCA1 and BRCA2, and had no other known breast cancer risks.

Their breast imaging is reviewed, showing clustering of multiple tumor foci in the breast directly under the area of phone contact
. Pathology of all four cases shows striking similarity; all tumors are hormone-positive, low-intermediate grade, having an extensive intraductal component, and all tumors have near identical morphology. These cases raise awareness to the lack of safety data of prolonged direct contact with cellular phones."

Cellphones and Health by Dr. Joel Moskowitz

 

In the last issue we explored the potential hazards of electromagnetic radiation from iPad use. We learned about warnings from the European parliaments and doctors' associations in various countries, and discussed the differences between pulsed digital wireless signals and continuous analogue radio waves. This time we are pleased to invite Dr. Joel Moskowitz to share his research findings regarding the health effects of cellphones.

 

I started studying the effects of cellphone radiation when Dr. Seung-Kwon Myung, a physician and epidemiologist from the National Cancer Center of South Korea, spent a year working in my center at UC Berkeley. He specializes in meta-analysis, a method by which data are combined across studies to generate more robust conclusions.

Straling en myeline

 

globalresearch.ca - "Addicted to Digitial Devices": Practice Safe Social Media

 

"Myelin is a fatty protective sheath that surrounds brain cells called neurons. Myelination is the process of acquiring this protection that takes place throughout childhood and adolescence and is not actually complete until the mid-20s and a little bit later in young males than females.

 

Low-powered but erratic pulses of microwave radiation from cell phones and other digital devices have been shown to interfere with myelin formation. This could increase the lifetime risk of developing neurodegenerative diseases such as Parkinson's and other problems such as hearing deficits and tinnitus – chronic ringing in the ears..."

Effect of 3G Cell Phone Exposure (…) on Non-thermal Activation (…) Stress Pathway in Rat Brain

 

PubMed - "Animals were exposed for 2 h a day for 60 days by using mobile phone (...). Result shows that microwave radiation emitted from 3G mobile phone significantly induced DNA strand breaks in brain. (...) Study shows that the oxidative stress is the main factor which activates a variety of cellular signal transduction pathways, among them the hsp27/p38MAPK is the pathway of principle stress response. Results conclude that 3G mobile phone radiations affect the brain function and cause several neurological disorders."

'Voodoo science' will not solve the causality-problem of EHS (Electro Hyper Sensitivity)

 

http://communities.washingtontimes.com -  Technological development of wireless communication has brought an unprecedented increase in human, animal and plant exposure to microwave radiation.

 

Currently available biomedical research indicates that even at the low levels permitted by the safety standards, radiation exposures induce acute biological effects. The possible impact of the chronic exposures is not known beyond, at the most, the first 10-15 years. We do not have the faintest idea what will happen when exposures will last for a lifetime.
