Will cell phones cause cancer? Some people say yes, some say no, and no one knows.
Everyone is not affected by the frequency and power of the mobile phone for a long time, which is not enough to draw a good conclusion. The FCC has confirmed that the mobile phone will not cause obvious harm to the human body (except of course when calling), but after 30-40 years, we may have brain cancer.
A recent study shows that at least-mobile phones have an effect on the brain. This is not an "irrelevant" discovery: we are surrounded by rays every day, and it does not seem to have an effect on the human body, and the same is true of mobile phones. This statement is reasonable. But the new report found that the activity of the brain near the antenna of the mobile phone is 7% higher than other places.
What does this mean? The researchers have no conclusion.
Scientists have found that calling the phone for 50 minutes is enough to change the activity of brain cells near the antenna.
But scientists from the National Institutes of Health said on Tuesday that it was unclear whether this was harmful to the human body, and that the relationship between cell phones and brain tumors was not determined.
This research by Dr. Nora Volkow was published in the Journal of the American Medical Association. She said: "What we found is that in the part of the brain that is closest to the antenna of the mobile phone, glucose metabolism (a sign of brain activity) will increase."
She said that the weak electromagnetic radiation emitted by the mobile phone could actually affect brain activity, which surprised her, but the research did not find whether the mobile phone would cause cancer.
"The study did not find this. What the study found was that the brain is sensitive to the electromagnetic radiation of the mobile phone."
Since the advent of mobile phones in the early 1980s, the number of mobile phones worldwide has surged to 5 billion.
