Researchers found that cancer rates in the central nervous system were almost equal in both long-term mobile phone users and people who do not use the handsets. This study has been termed as the most prominent one on the subject.
Worldwide,there are 5 billion cell phone subscribers and there are speculated fears among people that the electromagnetic fields emitted by holding a handset to the ear may lead to hazardous health effects.
This research was carried out by the researchers from the Institute of Cancer Epidemiology in Copenhagen who studied the entire population born in Denmark after 1925 by collecting data from the Danish phone network operators and the Danish Cancer Register. After analysis of data over 10,729 central nervous system tumours between 1990 and 2007,it was found that people who had used cell phones for 13 years or more had the same cancer rates as others.
The authors reported : “The extended follow-up allowed us to investigate effects in people who had used mobile phones for 10 years or more, and this long-term use was not associated with higher risks of cancer.”
“However, as a small to moderate increase in risk for subgroups of heavy users or after even longer induction periods than 10-15 years cannot be ruled out, further studies with large study populations, where the potential for misclassification of exposure and selection bias is minimised, are warranted.”
