The World Health Organization has announced a 10-year research into cell phone use. Talking with your cell phone for more than 30 minutes a day increases your risk of brain cancer by a third. In a study of more than 5 participants from 13 countries over the age of 30, more than 30 minutes of daily cell phone conversations showed a three-fold increase in the risk of brain cancer. According to the news of Radikal's Daily Mail, Experts advise that the use of mobile phones with headphones should not be placed directly in the ear but most mobile phone users prefer not to use mobile phones with headphones. Less than 30 minutes of cell phone use per day or whether using a headset was directly related to brain cancer was not observed. Experts say that mobile phone use has been intensified over the last 10 years, and that the use of mobile phones is less or indirect, causing no damage to the brain: we will see long-term losses of the mobile phone in the near future.
