The debate over cell phones cause brain tumors continue to show two new studies suggest that brain tumors do not increase because of the increased use of mobile phone - at least until the data that we look more close .
In the first two - the University of Oxford, International Agency for Research on Cancer ( IARC ) - Monitoring 791.71 thousand years - women in middle age seven - after reporting their cell phone usage in 1999 , 2005 and 2009.
Research has discovered in 1261 51680 invasive cancers and cancers of the central nervous system over time.
The investigation showed that there was no increase in cancer - including cancer of the brain - for women compared to those who did not use cell phones.
However, if users of non - mobile phone were with notebook users who use cell phones for more than ten years, compared , there was a 10% increase in meningioma risk. Although the results were clear, the researchers did not sufficiently take into account important finding .
In addition , compared to non-users of mobile phones, the long-term use (10 years +) cell phones increases the risk of acoustic neuroma by two and a half times. Maybe they did not think it was important because acoustic neuroma are called non - Hodgkin's and thus not a true cancer. That may be true, but there is no reason to ignore the increased risk .
According to research, these risks have increased the use of elevated mobile phone - what the risk " dose-dependent " .
If a risk is dose-dependent , it validates the causation element of the study. This means that the more a person's mobile phone , the higher the risk.

Study follows meningioma cases ...
Regarding meningioma, a recent study by Swedish researchers in the journal Environmental Health was published in July , also found an increased risk of minimal increase in cell phone usage .
This study followed 709 patients with meningioma and compared them with 1368 control subjects in question. They compared the use of mobile phone in both groups, and analyzed the data with a latency - the time monitoring the use - 25 years .
Here , the researchers found , once again, no increased risk - but safe . And the risk appears to increase with the increased use of mobile phone.
Two periods of time - between one and five years and over 25 years have an increased risk of meningiomas 30 % among those who used mobile phones for a period of 25 years risk.
In the highest quartile of use has the use of mobile and cordless phones at a higher risk of meningiomas , 30 % for mobile and 40% for mobile phones, and 80 % increased risk for LED the use of mobile phones.
The increased risk was found , especially for those corresponding to their phones about 40 minutes per day for 10 years , will be treated as a related 2376 hours of cumulative use
