A couple of weeks ago, the University of Manchester in England issued a press release on a new paper on brain cancer trends in the U.K., under the headline, "Mobile Phone Use Not Related to Increased Brain Cancer Risk." Clear and catchy — but wrong. Frank de Vocht and two collaborators actually saw a...

Users of cell phones have another reason to be cautious. An Austrian team has found that the risk of developing tinnitus, a ringing in the ears, doubled after four years. This is one of the first epidemiological studies to investigate the long-term effects of mobile phones on hearing.

Hans-Peter Hutter of the Institute of Environmental Health at the Medical University of Vienna, and coworkers report that the observed association is "unlikely" to be spurious and could have important implications for public health. Their new epidemiological study, based on 100 cases and 100 controls, will appear in an upcoming issue of Occupational and Environmental Medicine.

An essential part of the Interphone story is Appendix 2. Although not included in the paper, it offers a way to look at the risks free of some of the bias that so muddled the published results. It also provides a window on the controversy that deadlocked the Interphone group for four years.

There is a general consensus that the large number of abnormally low risks observed in Interphone is a sign of a systematic problem —selection bias— in the way that the study was carried out. As the Interphone group acknowledges, it is “unlikely” that cell phones could immediately provide protection against brain tumors (see main Interphone Story).

Men's Health has gotten into the act too. The May issue offers its take on cell phone radiation health risks with "Is Your Life on the Line?" by Paul Scott. He covers much of the same ground as Nathaniel Rich in Harper's —except his is shorter. Like Rich, Scott begins with the story of Lloyd Morgan, a brain tumor survivor and cell phone activist, who, Scott says, "has made it his mission to spread the message that cell phone radiation is carcinogenic."

Pity those who are trying to follow the cell phone–brain tumor story. Their sense of the cancer risk is most likely a reflection of the last thing they read or saw on TV —It all depends on whose sound bite they happen to catch.

Take, for example, a paper published earlier this month in the Journal of the National Cancer Institute (JNCI) by a team of Scandinavian epidemiologists, under a rather bland title — “Time Trends in Brain Tumor Incidence Rates in Denmark, Finland, Norway and Sweden, 1974–2003.” But its message is anything but: Because there has been no increase in brain tumors between 1998 and 2003, a period when the use of cell phones “increased sharply,” cell phones are cancer safe.

Saturday's lead story in the Telegraph made believe that the U.K. daily had gotten hold of the much-delayed and much sought-after final results of the Interphone study — and that they showed that using a cell phone does indeed increase the risk of developing a brain tumor. Under the headline "Mobiles: New Cancer Alert," the newspaper proclaimed that, "Long-term use of mobile phones may be linked to some cancers, a landmark international study will conclude later this year." In its inside pages were a number of related stories, notably "People Must Be Told About Mobile Phone Dangers, Say Experts" and a sidebar about Larry Mills who had developed a tumor "exactly where he held the phone." The story was pitched as an "EXCLUSIVE" and was soon picked up by many other newspapers and Web sites.

Senator Arlen Specter (D-PA) will hold a hearing on cell phones and health on September 14. So says Devra Davis, an activist scientist at the University of Pittsburgh. If Specter follows through, it would be the centerpiece of a conference she is organizing that week in Washington, as well as a triumph for Davis herself. She is on a mission to make cell phones a more visible public health issue in the U.S. and to secure funding for a major research program. It would be the first time in more than 30 years that the U.S. Senate has addressed RF/microwave health risks.

While we were away on a summer break, another Interphone paper was released online: An analysis of the incidence of meningiomas (brain tumors) among cell phone users in five Northern European countries. It comes from the same teams that have previously reported increased risks of both glioma (another type of brain tumor) and acoustic neuroma (a tumor of the acoustic nerve) among long-term users.

Today's New York Times features a column by Tara Parker-Pope on cell phones and brain tumors, "Experts Revive Debate Over Cellphones and Cancer." As of this afternoon, it is the most popular story (most e-mailed) on the Times Web site.

Next-Up, the European activist group, has posted the entire Larry King Live show, "Cell Phones: Are They Dangerous?," on its Web site. Only the ads are missing. Click here to see the 44-minute video. A transcript is also available.

It’s become axiomatic that wide acceptance of non-thermal effects will come from developing biomedical therapies rather than from studying potential hazards. The health effects work is mostly sponsored by those who don't want to find any. And they usually don't (cf: the USAF, EPRI, CTIA, FGF, MMF, etc.) So no one should be surprised that the latest advance comes from a small high-tech Israeli company, Novocure, which is looking for innovative ways to treat cancer. It's a breakthrough —most likely a major breakthrough.

Novocure uses weak 100-200 kHz electric fields —the company calls them tumor treating fields or TTFields— to stunt the growth of cancer cells, either by slowing down their proliferation or by killing them off entirely. The company has now demonstrated this in four different cancer cell lines. Even more impressive is that tumor growth has been curtailed in mice, rats and, in a small pilot project, ten human patients with recurrent brain tumors (glioblastoma).

An international team of researchers has found new evidence that long-term use of a mobile phone may lead to the development of a brain tumor on the side of the head the phone is used. In a study which will appear in an upcoming issue of the International Journal of Cancer, epidemiologists from five European countries report a nearly 40% increase in gliomas, a type of brain tumor, among those who had used a cell phone for ten or more years. The increase is statistically significant. In addition, there was a trend showing that the brain tumor risk increased with years of use. The new paper is posted on the journal's Web site.

The Karolinska group’s paper showing no increased risk of brain tumors among those who used a cell phone for ten or more years appears in the March 15 issue of the American Journal of Epidemiology. We first reported this result in December based on a brief announcement from Stockholm, but the published paper offers many more details.

One interesting item is the finding of a somewhat elevated risk of developing a glioma (a 60-80% increase) on the same side of the head as the phone was used. But, the Karolinska researchers also saw a lower than expected glioma risk on the opposite side of the head.

December 17, 2004

Epidemiologists at the Karolinska Institute in Stockholm have found no association between the use of cell phones and the risk of brain tumors.

“No increased risk was found for glioma or meningioma related to mobile phone use,” reports Stefan Lönn and coworkers at the Institute of Environmental Medicine. Lönn completed the study as part of his doctoral dissertation under the direction of Maria Feychting. This work is part of the Interphone study being coordinated by the International Agency for Research on Cancer (IARC) in Lyon, France.
