acoustic neuroma: Microwave News Article Archive (2004 - )

The cell phone cancer controversy will never be the same again.

The U.S. National Toxicology Program (NTP) is expected to issue a public announcement that cell phone radiation presents a cancer risk for humans. The move comes soon after its recently completed study showed statistically significant increases in cancer among rats that had been exposed to GSM or CDMA signals for two-years.

Discussions are currently underway among federal agencies on how to inform the public about the new findings. NTP senior managers believe that these results should be released as soon as possible because just about everyone is exposed to wireless radiation all the time and therefore everyone is potentially at risk.

The Supreme Court of Italy has affirmed a ruling granting worker's compensation to a businessman who developed a tumor after using a cell phone for 12 years. This is the first time that a high court —in any country— has ruled in favor a link between mobile phone radiation and tumor development.

Innocente Marcolini, a financial manager at an industrial plant in Brescia in northern Italy, used cell and cordless phones for five-to-six hours a day for 12 years. Then, one morning ten years ago, Marcolini sensed an unusual tingling in his chin while shaving. He was soon diagnosed as having a benign tumor on the trigeminal nerve, which controls facial muscles and sensations.

Marcolini filed for workers' compensation alleging that his wireless phones were responsible for the tumor. At first, his claim was rejected. But, in December 2009, the Court of Appeals in Brescia reversed that decision and, on October 12, Italy's Supreme Court affirmed the Appeals Court's ruling. No further appeals are possible.

The acoustic neuroma story is becoming quite compelling.

Researchers in Tokyo have reported that they too found more of these tumors of the acoustic nerve among long-term cell phone users —the third group to see this link. Those who used cell phones for more than 20 minutes a day for at least five years had three times more acoustic neuromas than expected. The Japanese team also saw a strong suggestion of a dose-response relationship: The longer people used cell phones —both in terms of minutes of daily calls and years of use— the greater their risk.

Mobile phones may present a cancer risk after all. Epidemiologists at the Karolinska Institute in Stockholm have found that the phones can increase the incidence of acoustic neuromas, benign tumors of the auditory nerve. The nerve is exposed to radiation during the normal use of a cell phone.

Those who used mobile phones for at least ten years, had close to twice the risk of developing acoustic neuromas, according to a team led by Dr. Maria Feychting and Prof. Anders Ahlbom of the Karolinska’s Institute of Environmental Medicine. Ahlbom is the deputy director of institute.
