Millions worldwide rely on cell phones to stay in touch. The rapid evolvement of this technology has brought some concern of health implications. Cell phones do emit a radio-frequency radiation. Although the radiation is very small, some experts are concerned, since the phones are held to the head, that there may be an increased chance of tumor growth. Early research has split experts on the risks of tumor development.
Researchers from the Department of Oncology at University Hospital in Sweden reviewed several studies on cell phone use and tumors. The results, published in the International Journal of Oncology , found that there was no significant association with cell phone use and overall tumor growth, but there was a pattern in ipsilateral (same side) tumor growth and cell phone use.
The review looked at several, previously published case-control studies. The studies were split into reviews of gliomas , meningiomas , and acoustic neuromas .
With gliomas:
With meningiomas:
In cases reviewing acoustic neuroma:
In both cases of increased risk, there was potential for recall bias. In recall bias the information had to be obtained through participants’ memory after they had been diagnosed. The diagnosis alone may affect how the participants remember details such as which side they use their cell phone.
More studies will be done to fully understand the long-term effects of exposure to waves from cell phone and other technology. There is currently a lack of evidence that cell phone use contributes to overall brain tumor development. Using headsets or speaker phones or texting are options that allow you to use a cell phone without having the radiation near your head.
