Cell phone Cancer Depth survey: May cause cancer but limited evidence

Whether the cell phone is carcinogenic, the prevailing view was that there was not enough evidence to show a link between the two, but a recent World Health Organization's recently published assessment report that "mobile phones may be carcinogenic" is the most authoritative assessment in the field of cell phone radiation affecting human health, but　　This is a inconclusive assessment, but it is a mockery of the radio industry and a renewed debate on the issue over the years.　　From May 24 to 31st, Lyon, France, 31 scientists from 14 countries gathered in the World Health Organization's International Agency for Research on Cancer (IARC) Conference room to evaluate research on cell phone and cancer relationships that scientists have been doing for years.　　May 31, the Working Group's chief scientist, Jonathan Smid, issued a statement saying that the evidence collected from the present concludes that ——— mobile phones may have some carcinogenic risks. The scientists eventually included the use of mobile phones in a "potentially carcinogenic" category.　　This classification means that there is some evidence that it can lead to human cancers, but far from the "summative" level, further research is needed. IARC the carcinogens into five categories, in addition to "may cause cancer", but also includes cancer, is likely to cause cancer, unknown, probably not carcinogenic.　　Among them, smoking and second-hand smoke are included in the "affirmation of cancer", "very likely to cause cancer" including the production of art glass and hair dryer, such as barber professional behavior, the use of mobile phone-owned "may cause cancer" is ranked thereafter.　　The report will be published in the July 1 Lancet Oncology.　　How is the conclusion produced?　　The assessment Report condensed a decade study although who first made the conclusion that mobile phones may cause cancer, the study of the problem was not the first. A year ago, the International Agency for Cancer Research (IARC) completed a 10-year study that cost 25 million dollars. , global scientists interviewed 2,708 glioma patients in 13 countries (a brain cancer) and 2,409 meningitis patients earlier. and set up the control group, the study concludes, "In general, there is no link between the use of mobile phones and the increase in the risk of these two diseases," but also indicated: " Due to the limitation of deviation and error, we can not get the exact conclusion analysis.　　To this end, IARC decided to organize a team of experts to evaluate all scientific research in the field of cell phones and cancer risk. As a result, the Group of Experts reviewed and evaluated hundreds of related scientific research on human cancer, experimental animal cancer, and concluded that exposure to electromagnetic radiation from wireless devices such as mobile phones could have long-term health consequences, especially as the risk of cancer may increase.　　Because there are so many people using mobile phones, and the number is growing, especially among teenagers and children, this is likely to become a public health problem. While scientists have stressed that the evidence for glioma and acoustic neuromas caused by cell phones is still "limited" and there is not enough evidence that cell phones can cause other types of cancer, in general, the use of mobile phones is "likely to cause cancer risk."　　The scientists did not quantify the cancer risk caused by the cell phone, but they noted that, according to a previous study, in the past decade, the average number of people using a cell phone for half an hour per day increased by 40%.　　Is the conclusion credible? may be carcinogenic but the evidence is limited IARC is the authority of the Cancer Research Institute, but the launch of the assessment report has been opposed by some organizations. In a statement, the International Wireless Federation quipped that the WHO organization "has done countless evaluations and has made similar conclusions about pickles and coffee in the past." "In the classification of IARC, Pickles and coffee are" likely to cause cancer ", which is indeed controversial. There is evidence that coffee may be associated with colorectal cancer, but on the other hand, there are studies that suggest that coffee may reduce prostate cancer.　　The study of Pickles was mainly concentrated in South Korea and Japan, and opponents believed that the study was based only on observational data and did not use scientific control group comparisons. The International Wireless Federation also said that the current classification "does not mean that mobile phone cancer", "even if there are deviations and other data errors, the current data research evidence is still limited." "The industry has also said that IARC has not made any new research, simply an assessment of past published research."　　The agency also said the Federal Communications Commission and the United States Food and Drug Administration had made statements that there was not enough scientific evidence to suggest that the use of mobile phones was linked to cancer and other health problems. In response to these objections, others are defending IARC, "the debate will continue," Henry Ley, a bioengineering expert at the University of Washington, said in a media interview, "but this is the first relevant statement from the World Health Organization telling people to be careful with such radiation." This group of experts comes from all over the world, some of which are very respectable researchers. If someone says that this group of experts is not good enough, then I do not know who to listen to.　　"What's the argument about?"　　Cell phone radiation damage rabbit DNA since the 80 's, global mobile phone users have soared to 5 billion, and research into the relationship between cell phone use and cancer has become the focus of controversy in the medical field in recent years.　　Electromagnetic radiation can be divided into ionizing radiation (high RF) and non-ionizing radiation (low RF) Two, the former with carcinogenic risk, such as x-rays, but there is no clear evidence that the latter will cause cancer, the cell phone is emitted by this low frequency of non-ionizing radiation.　　Many scientists believe that cell phone radiation its energy wave is too weak, does not break the chemical bonds or damage to DNA, causing cancer, and repeatedly stressed that the non-ionizing radiation will lead to cancer of the chemical mechanism is still a mystery.　　Animal experiments have shown that cell phone radiation can cause DNA damage to rabbits and their offspring, but as Irac reported last year, no epidemiological study has been able to link cell phone radiation to cancer risk directly. However, a study this year by the U.S. Health Department shows that mobile phones with less than 1 hours a dayWill increase brain activity, but scientists are not sure what that means.　　The report also notes that even a tiny number of radiation-frequency signals from the phone can cause significant changes in the brain, and scientists involved in the study believe that even low levels of ionizing radiation do not break chemical bonds, but can also cause damage. The debate in the scientific community is confusing for mobile users. In the face of potential health threats, the IARC's assessment report did not give advice on cellphone use, but participants said in the meeting that using hands-free devices such as earplugs, or texting, could reduce cell phone radiation. This reporter Jin mobile phone radiation has high and low who statement, immediately aroused concern in the mobile phone industry.　　May 31, a U.S. public welfare organization, "the United States Environment Task Force" immediately launched a report on the number of mobile phone radiation levels ranked.
