The notion that smartphone or cell phone radiation can trigger brain tumors continues to be debated. Several studies published in 2009 indicate a relationship with a brain tumor cell phone radiation. However, recent research says, it is still too early to conclude that cell phone radiation triggered brain tumors.
A major review study published by a committee of experts from UK, USA and Sweden concluded there was no convincing evidence that cell phone radiation relationship with risk of brain cancer. This also proves the lack of established biological mechanism by radio signals from cellular phones that can trigger tumors.
"Although there is still no certainty, the more evidence that contradicts bgukti belakamng with the hypothesis that the use of cell phones can cause brain cancer in adults," concluded the experts, published in the journal Environmental Health Perspectives, latest edition.
Research is surprising because it was published two months after the World Health Organization (WHO) and International Agency for Research on Cancer (IARC) announced that mobile phone use should be classified as carcinogenic or can cause cancer. Carcinogens cause cancer by altering the deoxyribonucleic acid (DNA) in body cells, and this is disturbing biological processes.
Anthony Swerdlow of the Institute of Cancer Research UK, who led the new study, as quoted by Reuters said that mobile phone use has increased since 1980 and reached number 5 billion handsets until this year. However, there has been no confirmed cases of mobile phone radiation relationship with tumor disease, especially brain tumors.
Significantly, other studies from several countries have shown no indication of increased brain tumor until 20 years after the introduction of mobile phones and 10 years after widespread use of mobile phones. Given the limited evidence, it is clear that the risk seems very small and very difficult to detect relationships with a brain tumor cell phone radiation.
"This is indeed a very difficult issue to be investigated," said David Spiegelhalter, Winton Professor of the Public Understanding of Risk at the University of Cambridge, who was not involved in this study.
In addition, because mobile phones have become an essential part of everyday life, industry experts say the health threat it is unlikely to stop people using mobile phones, unless the research about it really proved.
