Do Cell Phones Increase Brain Cancer Risk?

20.10.2008
Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors, according to an editorial in the November issue of the journal Surgical Neurology (http://www.surgicalneurology-online.com), published by Elsevier.

Recent studies have raised concerns that long-term exposure to electromagnetic fields (ELF) from cell-phone handsets can increase the risk of brain cancers and other nervous system tumors, according to the editorial by Dr. Ron Pawl, a neurosurgeon at Lake Forest Hospital, Lake Forest, Ill. He calls for collaborative research initiatives to determine whether the link between cell phones and brain cancer is real.

Scientists have long been concerned over the possibility that ELF exposure may increase the risk of brain cancers. Until recently, however, research has shown no clear link between cell phone use and brain tumors.

Earlier this year, a Swedish research group published an epidemiologic study suggesting an increased risk of brain cancers (gliomas) as well as acoustic nerve tumors (neuromas) in people using cell phones for ten years or longer. Tumors were more likely to develop on the same side as the cell phone was used. Other studies by the same group suggested that the use of wireless handsets in cordless home phones posed the same risk.

After reviewing the evidence, one author even suggested that long-term cell phone use is "more dangerous to health than smoking cigarettes." Other recent commentators have raised similar concerns.

The findings are alarming in light of the exponential growth of cell phones—now including widespread use by children and teenagers. The damaging effects of ELF, if any, might be even greater in the developing brain.

If the link is real, then rates of brain cancers should have increased over the last two decades. Some studies have reported that this is the case, particularly for the most malignant brain cancers. However, other studies have found a stable tumor rate.

Some commentators have suggested that apparent increases in the number of brain cancers might reflect the use of sophisticated imaging techniques like computed tomography and magnetic resonance imaging. "However, the fact that the incidence of gliomas, especially the more malignant varieties, is increasing […] warrants action on this issue," Dr. Pawl writes.

The problem, according to Dr. Pawl, is that no other research groups have performed actual studies showing a clear relationship between brain tumors and ELF. He calls on scientific societies to play a leading role in designing and conducting studies that will definitively determine the risks of brain cancer associated with ELF exposure, particularly from cell phones. "It seems that a cooperative effort by both the scientific community and state governing bodies will be needed," writes Dr. Pawl. "Some spearhead is now necessary in view of the magnitude and seriousness of the situation."

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
