The World Health Organization (WHO) announced today that radiation
from cell phones can possibly cause cancer. According to the WHO's
International Agency for Research on Cancer (IARC), radiofrequency
electromagnetic fields have been classified as possibly carcinogenic to
humans (group 2B) on the basis of an increased risk for glioma that some
studies have associated with the use of wireless phones.
This announcement was based on an extensive review of studies on cell
phone safety by a working group of 31 scientists from 14 countries, who
have been meeting regularly to evaluate the potential carcinogenic
hazards from exposure to radiofrequency electromagnetic fields. They
reviewed exposure data, studies of cancer in humans and experimental
animal models, and other relevant data.
More specifically, the IARC Monograph Working Group discussed and
evaluated literature that included several exposure categories involving
radiofrequency electromagnetic fields:
- Occupational exposures to radar and to microwaves;
- Environmental exposures associated with transmission of signals for radio, television, and wireless telecommunication; and
- Personal exposures associated with the use of wireless telephones.
"Given the potential consequences for public health of this
classification and findings," said IARC Director Christopher Wild, PhD,
in a news release, "it is important that additional research be
conducted into the long-term, heavy use of mobile phones. Pending the
availability of such information, it is important to take pragmatic
measures to reduce exposure such as hands-free devices or texting."
