The effect mobile phone radiation has on human health

Several reasons have been listed below why students of secondary should not own a mobile phone.
Over the past decade the world has seen rapid growth in cell phone users. Everyone from older adults to kids in high school seem to carry one glued to their ears, without understanding the possible health risks associated with the use of cellular telephones.
To begin with, a recent scientific journal published in 2007 titled Long term use of cellular phones and brain tumors, concluded after assessing results from many different studies that use of cell phones for more then 10 years does show increased risk for acoustic neuroma and glioma. Adding that the risk is highest for ipsilateral exposure, meaning tumor on the same side of the brain where phone mostly held.
Research scientists behind this journal assert that most studies to date on cell phone use and brain tumors have been mostly conducted with an insufficiently long latency period. This journal report gives excellent reviews of other studies and evidence of data entry errors, systematic bias and mathematical errors within those studies.
The effect mobile phone radiation has on human health is the subject of recent interest and study, as a result of the enormous increase in mobile phone usage throughout the world (as of June 2009, there were more than 4.3 billion users worldwide. Mobile phones use electromagnetic radiation in the microwave range, which some believe may be harmful to human health. A large body of research exists, both epidemiological and experimental, in non-human animals and in humans, of which the majority shows no definite causative relationship between exposure to mobile phones and harmful biological effects in humans. This is often paraphrased simply as the balance of evidence showing no harm to humans from mobile phones, although a significant number of individual studies do suggest such a relationship, or are inconclusive. Other digital wireless systems, such as data communication networks, produce similar radiation.
The World Health Organization, based upon the majority view of scientific and medical communities, has stated that cancer is unlikely to be caused by cellular phones or their base stations and that reviews have found no convincing evidence for other health effects. The WHO expects to make recommendations about mobile phones in 2010. Some national radiation advisory authorities have recommended measures to minimize exposure to their citizens as a precautionary approach.
