For years, it has been widely reported that radio waves emitted by cell phones increase the risk of brain tumors. Is it correct?
A new study shows that cell phones do not increase the risk of brain tumors.
For years, it has been widely reported that radio waves emitted by cell phones increase the risk of brain tumors. But experts at the University of Oxford (UK) recently said they found no evidence that mobile phones increase the risk of brain tumors.
The research has just been published in the Journal of the UK National Cancer Institute.
The study used data from 776,000 women over the age of 50 in the UK and found no link between mobile phone use and cancer risk.
The women were asked about their phone habits in 2001 and 2011.
By 2011, 75% of people in their 60s and 50% of people in their 70s were using a cell phone.
Of the 776,000 women, 3,268 developed a brain tumor – an average of 5,000 deaths in the UK each year.
Brain tumor cases were equally divided into two groups: those who used cellphones and those who didn’t. This means that mobile phone users have the same incidence of brain tumors as non-mobile phone users.
Study author Kirstin Pirie said: “These results suggest that normal cell phone use does not increase the risk of brain tumors.
Scientists say there isn’t enough data on the “phone-addicted” population, but the technology is getting safer.
Dr Joachim Schüz from the International Agency for Research on Cancer said: “Mobile technology has been improving”, so the last few generations of mobile phones have become more secure.
The doctor added that people should still “reduce unnecessary exposure” to cellphones if future research uncovers some problems.
Professor Malcolm Sperling, from Oxford University Hospital, added: “Further research is always needed, but this research should address many questions.”
