Casestudies: smartphone in BH dragen leidt tot borstkanker

"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.

"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.

Long-term exposure to microwave radiation provokes cancer growth: evidences from radars and mobile communication systems

 

Experimental Oncology (full text beschikbaar als PDF)/ PubMed - In this review we discuss alarming epidemiological and experimental data on possible carcinogenic effects of long term exposure to low intensity microwave (MW) radiation. Recently, a number of reports revealed that under certain conditions the irradiation by low intensity MW can substantially induce cancer progression in humans and in animal models. The carcinogenic effect of MW irradiation is typically manifested after long term (up to 10 years and more) exposure. Nevertheless, even a year of operation of a powerful base transmitting station for mobile communication reportedly resulted in a dramatic increase of cancer incidence among population living nearby. In addition, model studies in rodents unveiled a significant increase in carcinogenesis after 17-24 months of MW exposure both in tumor-prone and intact animals.

Plausible mechanism of action for low-intensity EMR exposure - voltage-gated calcium channels

 

The EMR Policy Institute - Author Martin Pall PhD writes:

 

One of the great puzzles about the action of electromagnetic fields is how can they influence the biology of our bodies? The reason that this is such a great puzzle is that these fields are comprised of low energy photons, with energies too low to influence the chemistry of our bodies. So how can they possibly influence our biology? Many have argued that the only thing that they can possibly do is to heat things, and yet it is very clear that levels of exposure that produce only the slightest heating have been repeatedly shown to produce substantial biological effects. Now this puzzle has been solved in a paper with the title of this email, published on line in the Journal of Cellular and Molecular Medicine, freely available on the publisher's web site:

Investigation of the Effects of 2.1 GHz Microwave Radiation on Mitochondrial Membrane Potential (ΔΨ m), Apoptotic Activity and Cell Viability in Human Breast Fibroblast Cells

 

"The cell viability of MW-exposed cells was decreased significantly. (...) The results of this study showed that 2.1 GHz W-CDMA modulated MW radiation-induced apoptotic cell death via the mitochondrial pathway"

 

http://www.ncbi.nlm.nih.gov/pubmed/23723005?dopt=Abstract

 

Note: W-CDMA is a 3G cell phone carrier system used in the U.S. by Verizon and Sprint to handle data transmission. We have few studies on this type of modulation.
