No connection between cancer and cell phones, experts argue

In May the World Health Organization published a report that said cell phones are “possibly carcinogenic.” Last month The Economist published a different report suggesting it simply wasn’t possible for the radio waves emitted by a cell phone to cause cells to mutate. Now, another group of research experts from Britain, the United States, and Sweden — who have studied the WHO report — are also arguing that there’s no connection between cell phones and cancer. “Although there remains some uncertainty, the trend in the accumulating evidence is increasingly against the hypothesis that mobile phone use can cause brain tumors in adults,” the group said in a recent report published in Environmental Health Perspectives. According to Reuters, a number of other studies have also been unable to find a link between increases in brain tumors and cell phones in the 10 years since cell phones have become commonplace. “This is a really difficult issue to research,” David Spiegelhalter, the Winton Professor of the Public Understanding of Risk at the University of Cambridge told Reuters. Spiegelhalter was not part of the study but said that it’s “clear that any risk appears to be so small that it is very hard to detect — even in the masses of people now using mobile phones.” More →

No way cell phones cause cancer, Economist contends

No way cell phones cause cancer, Economist contends

Following a report issued late last month by the World Health Organization suggesting cell phones may be carcinogenic, The Economist has published a response column dismissing the report as overblown. According to the report, low-frequency microwaves such as those emitted by cell phones simply do not have enough power to produce anything but extremely low levels of heat. “No matter how powerful the transmitter, radio waves simply cannot produce ionising radiation,” the column reads. “Only gamma rays, X-rays and extreme ultra-violet waves, which operate in the far (ie, high-frequency) end of the electromagnetic spectrum, along with fission fragments and other particles from within an atom, and cosmic rays (those particles’ equivalents from outer space) are energetic enough to knock electrons off other atoms to break chemical bonds and produce dangerous molecules called free radicals. It is these highly reactive free radicals that damage a person’s DNA, causing mutation, radiation sickness, cancer and death, depending on the dose.” The energy carried by these microwaves, the report contends, is approximately one million times too weak to produce free radicals.

Cell phones are ‘possibly carcinogenic,’ WHO report says

Cell phones are ‘possibly carcinogenic,’ WHO report says

According to a new report from the World Health Organization’s International Agency for Research on Cancer, “radio frequency electromagnetic fields” are “possibly carcinogenic to humans based on an increased risk for glioma, a malignant type of brain cancer associated with wireless phone use.” The agency met with with 31 scientists from 14 countries from May 24th through May 31st, 2011 to assess the potential carcinogenic hazards of cell phone usage. The report said that the results were “evaluated as being limited among users of wireless telephones for glioma and acoustic neuroma,” and that it was not relevant to finding conclusions for whether or not cell phones can cause other types of cancers. “Given the potential consequences for public health of this classification and findings, it is important that additional research be conducted into the long-term, heavy use of mobile phones,” IARC Director Chrisopher Wild said. “Pending the availability of such information, it is important to take pragmatic measures to reduce exposure such as hands-free devices or texting.” The full report will be published on July 1 in The Lancet Oncology.
