WHO:Cell phones may cause brain cancer

Radiation from cell phones could possibly cause cancer, according to the World Health Organization.

cell phones and radiation

In a report issued today, the International Agency for Research on Cancer (IARC), which is an arm of the WHO, said it now lists mobile phone use in the same category as lead, gasoline engine exhaust, and chloroform. Officially, cell phone radiation is listed as a "carcinogenic hazard."
Until today, the WHO's IARC had said that there were no adverse health effects from the use of cell phones. The wireless industry, including the CTIA lobbying group, and the Federal Communications Commission and U.S. Food and Drug Administration have also long maintained that cell phones are safe.
The CTIA, the wireless industry trade association in the U.S., was quick to point out that the WHO's IARC did not say that cell phones definitely cause cancer.
"IARC conducts numerous reviews and in the past has given the same score to, for example, pickled vegetables and coffee," John Walls, vice president of public affairs for CTIA, said in a statement. "This IARC classification does not mean cell phones cause cancer. Under IARC rules, limited evidence from statistical studies can be found even though bias and other data flaws may be the basis for the results."
The group also emphasized that the IARC's determination was based on reviewed published studies and was not the result of new scientific research.
"The IARC working group did not conduct any new research, but rather reviewed published studies," Walls continued. "Based on previous assessments of the scientific evidence, the Federal Communications Commission has concluded that '[t]here's no scientific evidence that proves that wireless phone usage can lead to cancer.' The Food and Drug Administration has also stated that '[t]he weight of scientific evidence has not linked cell phones with any health problems.'"
In response to Tuesday's news, an FCC spokesman said, "The FCC currently requires cell phones to meet safety standards based on the advice of federal health and safety agencies. We support the IARC recommendation for more research to clearly identify any potential health risks and, as appropriate, consider whether further actions may be required."
The new determination from the WHO's IARC was established at a meeting in France where a team of 31 scientists from 14 countries, including the United States, considered peer-reviewed studies about the safety of cell phones. The team said that it had found enough evidence to consider exposure to cell phone radiation as "possibly carcinogenic to humans."
The scientists reiterated what many in the field have said for years, which is that there are not enough long-term studies to decisively say one way or another whether cell phone radiation causes cancer. But there is enough data to show connections between exposure and health risks for consumers to be concerned.
 
Jonathan Samet, a medical doctor and professor from the University of Southern California, and the overall Chairman of the IARC's Working Group, which reviewed the studies, said in a statement today that "the evidence, while still accumulating, is strong enough to support a conclusion and the 2B classification. The conclusion means that there could be some risk, and therefore we need to keep a close watch for a link between cell phones and cancer risk."
The IARC has not yet published new guidelines for cell phone use, but the director of the organization suggested that concerned consumers take precautions to reduce exposure. He also emphasized the need for more research.
"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 Christopher Wild said in a statement. "Pending the availability of such information, it is important to take pragmatic measures to reduce exposure such as hands?free devices or texting."
The IARC said in a statement that it considered hundreds of scientific articles, including some recent articles that had been published as a result of the 10-year Interphone study.

It was decided that three blocks of 10 MHZs each out of available 3G spectrums would be immediately offered for auction and existing operators can participate in this round as well. New players will also be invited but with provision that if new player is successful in bid then they would be eligible to start operation only after March 2013 when moratorium on new licensing, as per Government’s agreement with Etisalat, would expire.
More spectrums would be made available for 3/4 G services and offered for auction with the provision that winners of such auction will receive amended licenses and allocated frequencies by March 2013 and as such will be able to start their services thereafter.
In order to ensure professionalism and transparency, it was also decided that a committee of Public Sector stakeholders including representatives from Ministries of Finance, Information Technology, PTA and representative of Frequency Allocation Board would supervise auction process. PTA would devise an appropriate methodology to conduct varying component of this auction as decided under the supervision of the Committee.
