The phone cancer is the mainstream view is that there is not enough evidence to make a connection between the two shows, however, the published World Health Organization recently published a review of the report, "mobile phone can cause cancer," which is the area of mobile phone radiation on human health, the authoritative assessment of the report, but this is not a final assessment of the radio industry aroused the scorn, but also to the debate on the topic, and update again.
May 24 to 31, Lyon, France, from 14 countries, 31 scientists from the World Health Organization attributed gathered IARC (IARC) meeting room, the scientific community over the years and made mobile phone connections between cancer evaluation.
31. May, Jonathan Smith, chief scientist of the working group said in a statement Germany can from the current collection of evidence to the conclusion --- with some cell phones cause cancer.
Scientists use the phone, finally, in the "probable carcinogen" in the category. This classification means that there are some indications that lead to human cancer, but far from the "Summary" with him, require further investigation.
IARC carcinogens into five categories, plus "can cause cancer, but also causes such as cancer, probably cancer, unknown, it may not lead to cancer. Among them, smoking and passive smoking have been included in the "definitely cancer", "probable carcinogen", including the manufacture of glass art and common hair dryer hairdresser and other professional behavior, use the phone belongs to a "potentially carcinogenic" on the line in the behind.
The evaluation report will be on 1 July of the "Lancet Oncology" published.
Conclusion generate How?
Condensed decades of research assessment
Although the first time who has the conclusions of the phone has to cause cancer, but studies on this subject is not the first time
A year ago, completed IARC (IARC), a fee of $ 25,000,000 which took decades of research. Period, the scientists were the world in 13 countries, 2708 patients with gliomas (a type of brain tumor) and the 2409 act of meningitis patients previously interviewed and set the group concluded not see the study that "the entire run, cell phone use and an increased risk of both the relationship between disease, "but that" because of the limitations of bias and error, we can not draw firm conclusions on analysis. "
To that end, decided to IARC expert group on mobile phones and cancer risk assessment of all areas of scientific research to organize.
Thus, the group of hundreds of reports of human cancer, cancer and other animals to relevant scientific research, the assessment have been reviewed and finally to the following conclusion: Exposure to mobile phones and other wireless devices, electromagnetic radiation, long-term health effects may have particular is likely to increase cancer risk. Because so many people, mobile phones and the number is growing, especially among young people and children, this can become a problem of public health.
While the scientists emphasized that mobile phone induced glioma, acoustic neuroma evidence even more "limited," there is not enough evidence to cause the phone comes the other cancers, but overall cell phone use is "probably carcinogenic risk."
The scientists did not cause the phone to the quantitative cancer risk, but they mentioned that earlier, according to a study on the day of the last ten years on average half an hour of people use mobile phones, glioma risk appears by 40%.
Conclusions are credible?
However, limited evidence to be carcinogenic
IARC is the authority of the cancer research organization, but the introduction of this assessment report resistance from some organizations. Federation of International Wireless, said in a statement Ironically, the WHO agencies "made do a variety of assessments, pickled vegetables and coffee in the past back to a similar conclusion."
In the IARC classification, cucumbers and coffee are "probably carcinogenic", it is controversial indeed. There is evidence that coffee may be related to colon cancer, but other studies have shown that coffee can reduce prostate cancer. The research focuses on the pickles in Korea and Japan, the opponents argue that this study only data based on observation, not a scientific control group comparison.
International Federation Wireless also said that the current classification "does not mean that mobile phones cause cancer," "even if it bias and other data errors, the data of the current evidence is still limited."
The agency also said in the industry, IARC has not made any new study, only the last full assessment of the published studies. The agency has also proposed that the Federal Communications Commission and the U.S. Food and Drug Administration have to stand, saying it is not enough scientific evidence that mobile phones and cancer and other health problems associated.
In response to these objections, it was defended for the IARC, "go further debate," the University of Washington bioengineering experts Hengli Lai said in an interview: "This is the first say in connection with the World Health Organization statement that people should be careful, such radiation. group of experts from around the world, some very reputable researchers. If someone says this group of experts is not good enough, then I do not know who is listening. "
Arguments come from?
Rabbit DNA damage cell phone radiation
80 years from the date of the last century, the global mobile phone users rose to 50 million, while the relationship between cell phone use and cancer research in the medical field in recent years at the center of controversy.
Electromagnetic radiation can in ionizing radiation (high frequency) and non-ionizing radiation (low frequency) to be with the former having a cancer risk, such as X-ray, etc. divided, but no definitive evidence to cause the latter would become cancer to launch mobile phones, this low frequency non-ionizing radiation.
Many scientists believe that the energy wave of mobile phone radiation is too weak, damaged or chemical bonds cause DNA damage, cancer, and repeatedly emphasized that, the non-ionizing radiation cause cancer of the chemical mechanism has Rengshi Wed
Animal experiments have shown that the radiation from mobile phones can cause DNA damage rabbits and their offspring, but the same as last year's report IRAC, there are no epidemiological study on a cell phone radiation and cancer risk will be directly linked.
But the U.S. health system and a study this year showed that less than 1 hour a day cell phone use leads to an increased activity of the brain cause, but scientists do not know exactly what that means. The report also noted that even traces of cell phone radiation frequency signals can also cause significant changes in the brain to think study participants scientists that even small amounts of non-ionizing radiation, not against the bond, but can also lead to injuries.
Scientific arguments, so that mobile phone users are confused. Face a potential threat to health, although the IARC not give evaluation report, the proposal to use mobile phones, but the participants of the meeting, to amend the use of ear plugs and other hands-free, or to text messaging, a mobile-phone radiation to reduce . 2011-6-6
