For the first time stated that exposure to electromagnetic fields from mobile phones increases the risk of glioma. But scientists say the evidence is expressed possibility but is not conclusive.
The World Health Organization (WHO) and the International Agency for Research on Cancer (IARC) said Tuesday that the filing emanating cell phones has a “possible” risk of brain cancer in humans, according to the latest research science.
WHO reported that radiofrequency electromagnetic fields used by mobile phones, “cause” cancer in humans. This warning was launched in conjunction with the IARC, based in Lyon (France), which assesses the risks of cancer and makes recommendations to the authorities. “There is some evidence of an increased risk of glioma,” or brain tumor, said Kurt Straif, chief scientist at IARC, but added that “so far provided no factual evidence that the use of cell phones cause cancer.”
The research began in 2004 found a 40% increase risk of brain tumors among users who used cell phones an average of 30 minutes a day for a period of ten years. Dr. Jonathan Samet of the University of Southern California (USA), leader of the group that has analyzed the issue, explains that “the accumulated evidence is strong enough to support a classification of these waves in Group 2B [possibly carcinogenic compounds]. ” He notes that “this means that there may be some risk of cancer by use of phones, but we still need to better analyze this relationship.”
Evidence and explanations
Straif explained that scientific evidence shows that the use of text messages and “hands free” offer “reduced exposure” to the filing of the cell. For its part, the WHO said that since the beginning of the nineties there is concern that cell phones can be “harmful” to consumers. Meanwhile, the Federal Communications Commission United States explained that the devices meet the highest rates of absorption by the body are safe.
For this recommendation on phones was a group of previous work with 31 scientists from 14 countries. IARC also conducts studies on snuff, alcohol, processed foods and certain drugs and chemicals.
