Research led by the Institute of Cancer Epidemiology in Copenhagen is investigating more than a 358.000 mobile phone users for almost 18 years. They find the risk of central nervous effect long human afflicted by cancer is almost the same on two different types of participants, users and non-mobile users.
They studied the entire population of Denmark are over 30 years old and was born in Denmark after 1925 to gather information about customer's mobile phone network operator of Denmark and from Denmark's list of Cancer.
They analyzed data from a case of 10.729 central nervous system tumors that occurred between 1990 to 2007. As a result researchers look at when the figure bounded by dividing the kind of person that is users and non users of mobile phones look almost the same level of cancer cases in these two types of research participants, both users and non users.
The researchers said they observed no increased risk for the occurrence of tumors or cancer in the central nervous system on mobile phone users.
However, they see there is little relationship concerning the increased risk subgroup heavy user or after a period of induction are longer than 10 to 15 years. Further research with large populations, where the potential exposure and classification errors of selection bias that minimized any will do.
"This research supports most of the other report that found no adverse effects from the use of the phone under normal exposure," explained Professor Malcolm Sperrin, Medical Director of the Physics of the Royal Berkshire Hospital, United Kingdom in response to this research.
