To begin a new scientific journal published in 2007 entitled Long-term mobile phone use and brain tumors, concluded after evaluating the results of many studies on the use of mobile phones in more than 10 years have shown an increased risk of acoustic neuronal and glioma. Adds that the risk is highest for ipsilateral exposure, meaning tumor on one side of the brain where phone mostly held.
Research
ers behind the magazine says that most studies to date on mobile phone use and brain tumors usually performed at a sufficiently long latency. This report provides an excellent journal reviews of other studies and documentation for handling errors, systematic bias and mathematical errors in these studies.
Argument on studies of short-term recall of mobile phone use is used, is well supported by evidence that the actual use of mobile phones is usually underestimated by users and slightly overestimated by heavy users that the strength of data intercom studies. Similarly, if results show an increased risk of glioma and acoustic neuroma from several other studies on the use of mobile phones in more than 10 years supported their conclusion.
Also included a second study published in 2006 with three researchers in Sweden have an increased risk of malignant brain tumors into groups depending on the use of mobile and wireless phones for more than 10 years. Like the aforementioned survey, also researchers in this report mentions the so-called weak long trials is their short latency.
Evidence of error in surveys, for example, Danish interphone study where much data entry error had occurred because of difficulties in understanding words Galioma patients from paralysis, is justified. They claim that their methodology for assessing the use of mobile and cordless phones by questionnaires to more sensible.
Moreover, interesting evidence brought up in this magazine for a full REFLEX study is important to mention here. The REFLEX study, which tested for genotoxic effects in cells exposed to high frequency electromagnetic fields on the SAR (whole body Specific Absorption Rate) levels between 0.3 and 2 W / kg signs. Increase in single and double strand DNA break choromosomal find abnormalities were observed in fibroblasts and the intracellular increase of free radicals in HL-60 cells.
Information from the REFLEX study combined with data from their own research, Swedish researchers concluded that the current allowed SAR 2 W / kg in Europe is inappropriate.
Conversely, it is important that our readers know that the maximum SAR level in the U.S. and Canada has a limit of 1.6 W / kg (FDA).
Finally, a magazine published in 2007 mobile phone and risk of glioma was five northern European countries, shows mixed results. These special surveys findings were based on a combination of data from Denmark, Finland, Norway, Sweden and Southeast England, where mobile phones are widely used for at least a decade. This study looked at reasonably large group of people. All patients with a glioma in 2530 and 6,581 controls had participated in this study.
Yet it is surprising to know that their conclusions are not so clear as in the previously mentioned studies. This study claims to be an increased risk of glioma are among groups most at risk. Neither they found no significant correlation between categories with duration of use, years since first use, cumulative number of calls or cumulative hours of use.
They also claim that no increased risks when analogue and digital phones were tested separately. But this study found a series of tests on a possible link. This link between the reported ipsilateral use 10 or more years ago associated with significantly increased risk of glioma, and there was a growing tread with years since first use on the ipsilateral side.
Finally, we recommend that consumers seek information about what SAR level their mobile phone user. SAR information is easily found in instructional techniques and materials shipped with the phone or can be found at many sites. We advise consumers to mobile phones which operate at the lowest possible value of SAR, and try to use cell phones while driving or in a hands-free headset for mobile phones to invest until there is greater use of absolute proof has been obtained.
