A Swedish study finds that users of digital phones in rural areas may be at greater risk of brain cancer. Its authors say the link is troubling, although they acknowledge that the amount of data is small and wider research is needed to amplify the findings.
Other research have been done during the past 12 years. The results are the following:
* The brain cancer patients didn't report more cell phone use than the subjects who were free of brain cancer. In fact, for reasons that remain unclear, most of the studies showed a tendency toward lower risk of brain cancer among cellular phone users.
* When different types of brain cancer were considered, none were consistently associated with cell phone use.
* When specific locations of tumors within the brain were considered, no associations with cell phone use were found.
* None of the studies showed a clear link between the side of the head on which the brain cancer occurred and the side on which the cellular phone was used. |
