According to a large long-term study, cell phone use does not increase the risk of brain tumors. The study from the United Kingdom started back in 1996.
An analysis of the UK Million Women Study, which has been ongoing in the United Kingdom for more than 20 years, found no evidence of increased tumor risk with chronic cell phone use. This was reported by a team led by Joachim Schüz of the International Agency for Research on Cancer (IARC) in Lyon in the Journal of the National Cancer Institute.
In the study, launched in 1996, hundreds of thousands of women answered questions about their use of cell phones for the first time in 2001 and then again in 2011. Of the nearly 800,000 women who completed the first questionnaire, almost 3,300 later developed a brain tumor. It did not matter when or how often the women had used a cell phone.
Less radiation with newer cell phones
Because cell phones, unlike other electronic devices, are used near the head, questions about possible health risks arose years ago. The German Society for Neurology reported in the study that the radiation was not sufficient to damage the genetic material in the cell nuclei and cause cancer. Nor was the energy from the phones enough to raise body temperature, for example.
The study’s authors point out that radiation has decreased significantly with ever newer generations of cell phones. So today, even with excessive use, one is probably exposed to the same amount as with moderate use of cell phones of the first two generations.
