according to the USA TODAY reported, according to the National Cancer Institute Journal (Journal of the National Cancer Institute), Thursday (3rd) published on the Web article points out that the Nordic country of 4 researchers found that, since 1998-2003 between 4 cell phone usage sharply increased, but diagnosed with brain cancer does not increase in the number of cases. results of this study is also most other research findings, included a United States survey on 1987-2005 study on the incidence of brain tumors.
International Center for research on cancer (International Agency for Research on Cancer) may also have a long-term multinational study is expected to be announced within a few months.
United States society for cancer (American Cancer Society) Michael Thun said, some people will be used for mobile phone electromagnetic wave emitted by mobile phones had misgivings, however, non-ionizing radiation of electromagnetic waves emitted by mobile phone is a low-frequency radio waves, this lack of radiation energy is too weak to damage DNA, And scientists understand at present without any biological procedure are affected by electromagnetic wave will produce brain cancer.
Thun said, such as is produced by the atomic bombing of the rays is well known it will certainly lead to cancer that?s right.
based on the content, it is possible their 16 million adults in the study of the number of samples are too small, slight increased risk of difficult to find, especially if your brain tumors occur in specific subgroups.
M.D.Anderson Cancer Center in Houston said Melissa Bondy, there may be brain cancer takes over 5-10 during the year to build.
Bondy noted, correlation between phones and cancer research there in many major obstacles. Even if the study can be found increased incidence of brain cancer, not on behalf of the mobile phone must have been the culprit. Bondy believes that as such a study can find relations between the two, but cannot prove causal relationships to each other, and many other trends also explains changes in the incidence of cancer.
and in fact people who worry that phone may cause now has almost entirely in the risk of exposure to electromagnetic waves, they can use headphones, loudspeakers, or Bluetooth headset.
Bondy call for now should still be cautious against cell phone use, especially for children, because their brain is still under development.
