Mobile phones not linked to increased brain tumour risk

23.01.2006


Mobile phones are not associated with an increased risk of the most common type of brain tumour, according to the findings of the first UK study of the relationship between mobile phone use and risk of glioma.



A four-year study by the Universities of Nottingham, Leeds and Manchester, and the Institute of Cancer Research, London, found those who had regularly used a mobile phone were not at a greater overall risk of developing this type of tumour. The research is published online by the British Medical Journal.

There was no relationship between the risk of glioma and number of years since first use of a mobile phone, lifetime years of use and cumulative number of calls or hours of use. Risk was not associated with phone use in rural areas, which had been found to be associated with an increased risk in an earlier Swedish study.


A significantly increased risk was found for tumours which developed on the same side of the head as the phone was reported to have been held, but this was mirrored by a decrease in the risk on the opposite side of the head — making it difficult to interpret as a real effect.

This finding may be due to people with glioma brain tumours linking mobile phone use to the side of the tumour and therefore over-reporting the use of a phone on the same side as their tumour. This results in under-reporting use on the opposite side of the head, say the authors.

Professor Kenneth Muir, of the Division of Epidemiology and Public Health at Nottingham University Medical School, is a co-author of the paper.

Mobile phones have been available in the UK since 1985, but widespread use did not begin until the late 1990s making the number of long term users (over ten years) quite small. This study had limited numbers for estimating the risk of using a phone over a long period.

Early mobile phones were designed to use analogue signals and emitted higher power than current digital phones but the study showed no increased risk of glioma brain tumours with the use of analogue phones.

The study authors concluded: “This study suggests that there are no substantially raised risks of glioma in the ten years after first mobile phone use. Only future studies will be able to address longer latency periods for the development of glioma.”

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
