Study Links Cell Phones To Brain Cancer Risk
by Dr. Mercola
Concerns have been raised about whether cell phone use can be linked to the development of brain tumours. Now, a study from Swedish researchers provides evidence backing the claim.
Researchers at the Karolinska Institute in Stockholm, Sweden, based their findings on questionnaire and interview data obtained from 209 persons with brain tumours and 425 healthy control subjects. In a 2-year study, the team found an increased risk in anatomical areas of the brain exposed to microwaves during a mobile phone call. This risk holds even when statistical adjustments are made for other risk factors including ionizing radiation and laboratory exposures.
The researcher pointed out, however, that most of the people in the study used the older analog system, which gives two to three times higher exposure than the digital system, which is now mostly used -- at least in Europe. Larger studies are necessary to make firm conclusions. The investigators have a much larger brain tumour study ongoing with about 1,500 incident patients and 1,500 controls and the results are expected within one year.
In light of their current findings, the authors offer several suggestions about cell phone usage. Use an earpiece to reduce exposure to the brain and, in a car, use an external fixed antenna. Otherwise, your exposure to microwaves might even be higher than using the phone outside the car. In addition, extended conversations should be conducted on a regular corded telephone.
Insofar as children are concerned, since the developing brain might be more sensitive to microwaves, children's exposure should be limited. One useful tip is to find out the specific absorption rate (SAR) value of various cell phone types. The SAR may differ by as much as a factor of 20 between different brands.
It is reprehensible to even consider that someone would allow a child to use a cell phone. The danger is far too great. We all need to reduce our exposure. The best way is to minimize their use to the smallest amount possible. Secondly, only use digital rather than analog phones, as the radiation dose is reduced by up to 90%. Thirdly, only use them with a head set. Please review the other articles for further information.
