De WHO - World Health Organisation komt met een waarschuwing dat mobiele telefoons kanker kunnen veroorzaken, voornamelijk hersentumoren. Dit bericht Medscape vandaag op hun website. Komende week komt in The Lancet een studierapport vrij die deze waarschuwing onderbouwt. Er ligt een studierapport uit 14 landen van 21 wetenschappers die de resultaten uit vele studies hebben samengevat en geanalyseerd. En hun conclusie liegt er niet om, zeker als je bedenkt wat voor impact dit kan hebben wereldwijd. Hier alvast enkele citaten uit Medscape gehaald waar het volledige artikel, hier klikken, te lezen is. Onderaan staat een artikel over wat er precies gebeurt door de mobiele "straling".

This announcement was based on an extensive review of studies on cell phone safety by a working group of 31 scientists from 14 countries, who have been meeting regularly to evaluate the potential carcinogenic hazards from exposure to radiofrequency electromagnetic fields. They reviewed exposure data, studies of cancer in humans and experimental animal models, and other relevant data.

More specifically, the IARC Monograph Working Group discussed and evaluated literature that included several exposure categories involving radiofrequency electromagnetic fields:

Occupational exposures to radar and to microwaves;
Environmental exposures associated with transmission of signals for radio, television, and wireless telecommunication; and
Personal exposures associated with the use of wireless telephones.

"Given the potential consequences for public health of this classification and findings," said IARC Director Christopher Wild, PhD, in a news release, "it is important that additional research be conducted into the long-term, heavy use of mobile phones. Pending the availability of such information, it is important to take pragmatic measures to reduce exposure such as hands-free devices or texting." ..............

Some of the strongest evidence supporting a link between brain tumors and cell phone use comes from a series of Swedish studies, led by Lennart Hardell, MD, PhD, from the Department of Oncology, Orebro Medical Center. These studies showed that risk increased with the number of cumulative hours of use, higher radiated power, and length of cell phone use. They also reported that younger users had a higher risk. (Int J Oncol. 2006;28:509-518; Int Arch Occup Environ Health. 2006;79:630-639; Arch Environ Health. 2004;59:132-137; Pathophysiology. 2009;16:113-122).

The issue of cell phone safety was to have been settled once and for all by the huge 13-nation industry-funded Interphone study. But to date, the industry-funded Interphone studies found no increased risk for brain tumors from cell phone use, with only 4 exceptions. The findings contradicted the Swedish studies, which were independent of industry funding.

Consistent with the literature, there is no consensus among physicians and scientists about the severity of risk, or if one even exists. One issue in attempting to evaluate the potential connection between brain tumors and cell phone use is the relatively short period of time that these devices have been heavily used in a large population and the long latency period for many tumors.

The National Cancer Institute, for example, has stated that although a consistent link has not been established between cell phone use and cancer, "scientists feel that additional research is needed before firm conclusions can be drawn." In a similar fashion, the American Cancer Society points out that even though the weight of the evidence has shown no association between cell phone use and brain cancer, information on the potential health effects of very long-term use, or use in children, is simply not available...........Read more>>>>>>

Onderzoekers hebben aangetoond dat langdurig mobiel belllen invloed heeft op het glucose metabolisme bij het oor waarmee gebeld wordt. Tot nu toe is alleen gemeten of het metabolisme in het hele hoofd zou veranderen en dat bljikt niet zo te zijn maar nu hebben wetenschappers aangetoond dat in het hoofd dat dichtbij de antenne van de mobiele telefoon zit er wel degelijk sprake is van veranderingen van het metabolisme van de glucosespiegel. Of dit ook schadelijk voor de gezondheid zou zijn is niet te zeggen op basis van dit onderzoek, maar de wetenschappers spreken wel hun verontrusting hierover uit. En raden bellers aan om zoveel mogelijk handsfree te bellen waarmee de mobiele telefoon wat afstand neemt van het hoofd van de beller.

Cell Phone Use Affects Brain Glucose Metabolism

February 23, 2011 — Use of a cell phone for as little as 50 minutes at a time appears to affect brain glucose metabolism in the region closest to the phone's antenna, a new study shows.

Investigators used positron emission tomography (PET) during cell phone use in the on and then off positions and found that although whole-brain metabolism was not affected, metabolism was increased in the orbitofrontal cortex and the temporal pole areas of the brain while the cell phone was on, areas that are close to where phone's antenna meets the head.

"We do not know what the clinical significance of this finding is, both with respect to potential therapeutic effect of this type of technology but also potential negative consequences from cell phone exposure," said lead study author Nora D. Volkow, MD, from the National Institute on Drug Abuse in Bethesda, Maryland, during a teleconference.

In the interim though, she recommends using hands-free devices or speaker-phone mode to avoid direct contact of the telephone with the head. Previous work suggests that if the phone is a foot or more away it is very unlikely to have any effects, she said. "So there are some very easy solutions that don't cost anything for those who want to play it safe."

Caution may be particularly necessary for children and adolescents whose neural tissue is still developing, Dr. Volkow noted. This is also a population who started their lives with cell phones and can expect to be exposed for years to come, she added.

Their report appears in the February 23 issue of the Journal of the American Medical Association. Read more>>>>>
