World Health Organization (WHO) has observed that there is no increased risk of cancer in cellphone users. But the new evidence makes the WHO announced that mobile phone radiation should not be ignored because it can be caused brain cancer.

But the announcement this time, the WHO said could not rule out that risk because there has been little research on effects of long-term cell phone use.

Recent research reveals mobile phone radiation can cause brain cancer risk. Mobile phone radiation with carcinogenic substances categorized as dangerous as lead, smoke exhaust, and chloroform.

This was announced by World Health Organization, World Health Organization (WHO), as quoted by CNN and the BBC .

WHO mentions the possibility of brain cancer risk for cell phone users who do not use mobile phones and almost the same magnitude. So that WHO can only remind the risk for mobile phone users more wise to use his cell phone.

Research conducted by a team of 31 scientists from 14 countries, including the United States. The decision was made after more in-depth review about the safety of using mobile phones. The team found sufficient evidence to categorize as a type of cell phone radiation harmful substance to humans.

The team found evidence of increased risk of glioma brain cancer and increased acoustic neuroma for mobile phone users. But can not draw conclusions for other types of cancers.

This finding is somewhat contrary to previous research results are also conducted by the WHO. In 2010, WHO released the results of observations during 10 years showed that there was no increased risk of brain cancer in particular glioma and meningioma.

In a study involving 13,000 mobile phone users in 13 countries, the duration of the use of mobile phones ranges from 2 to 2.5 hours / month. While the maximum duration is 1640 hours in the next 10 years, or an average of 1.5 hours / day.

Today the European Environment Agency has been pushing for further study. This independent body to reveal the phone can pose a risk as great as smoking, asbestos and leaded gasoline.

Related to the latest findings about the dangers of cell phone radiation, the head of a prominent cancer research institute at the University of Pittsburgh sent a memo to all employees urging them to limit cell phone use because of possible cancer risks.
