The confirmation research studies are not complete but precautions are advised in the use of cell phones. Cell phones are low power radio devices that emit electromagnetic radiation. The concern by investigators is that ionizing radiation can be absorbed by tissue can cause cancer in areas exposed to the radiation, in this case the brain. In 1993 on CNN’s Larry King Live, Dr, David Perlmutter, a neurologist, was the first to raise an alarm when he stated that his patient’s brain tumor was located in area where she could have received radiation form her cell phone antenna.
Lai and Singh in 1994 reported tumors in rats with whole body exposure to radiation from a cellular phone antenna. There have been various laboratory studies over the years assessing RF exposure’s effect on chromosomes and DNA breaks and addition animal studies. It was not until 1999 that J. Muscat associated cell phone use with a brain glioma tumor that FDA scientists became interested. A Swedish study at that same time show no connection between brain cancer and cell phone usage. December 2001, the National Cancer Institute concluded that if there was any increase risk for glioma, it was a very small risk. Research by the Danish in 2001 found that subjects were no more likely than any one else to suffer brain or nervous system cancers, nor leukemias or salivary gland tumors. The Berkeley Journal in 2001 questioned the safety of cell phones.
June 2002 Washington University School of Medicine stated that cell phones do not appear to cause cancer in rats. January 2004 the British government went on record to say that the present research did “not give cause for concern” that the devices cause cancer “nor any other adverse health effect.” The British government announced in January 2004 that there is not a link between cell phones and cancer, but more research needed to be done. A Both a Finnish study and a Danish study in 2005 showed no increased risk for brain tumors related to cell phone use and frequency.
October 2007 a comprehensive independent study on people exposed to cell phone RF for more than 10 years had a 2 times risk for developing brain cancer on the side of the head where the cell phone was used. Tokyo Women’s Medical University in February 2008 research found the association unlikely. Research scientists in Britain, Denmark and Sweden announced June 2008 that they were launching the largest independent study on 200,000 adults to determine long-term effects of cell phone use and whether or not it causes brain tumors, Alzheimer’s and Parkinson’s diseases. September 2008 Swedish researchers from the University Hospital in Orebo, Sweden reported at the first international conference on mobile phones and health that children and teenagers were five times more likely to develop brain acoustic neuromas and 50% more likely to develop brain gliomas. The British government has formerly adopted a policy for limited the use of cell phones in children.
The medical community acknowledges that the majority of studies in the literature have found no links to cell phone usage and brain cancer or any other cancer, but the medical community also feels that we should not wait for the results of other confirmation studies, but rather caution should be given to parents to limit their children’s cell phone usage and the following safety precautions should be in use for all cell phone users who wish to limit electromagnetic radiation exposure:
Keep the cell phone away from the head and body, use speaker phone or a wireless headset.
Limit the use of the cell phone in public were others may be exposed as on buses, trains, planes, etc.
Limit children use of cell phone to emergencies.
Use cell phones as a means of contact and limit the length of phone calls.
Communicate by text messaging rather than phone
Switch sides of your head while using the phone more frequently.
Choose a telephone with the lowest Specific Absorption Rate (SAR) possible.
