Yang Yang, 12 years old from Guangdong, is a primary school student. Every weekend or during winter and summer vacations,He is always obsessed with playing games, playing for one or two hours at a timeDuring holidays, playing with mobile phones can last until one or two o'clock in the middle of the night before going to bed.

At first, after playing games, the child always reported dizziness, headaches, dizziness, etc. His parents advised him to play less on his phone, but he also refused to listen. Once, while playing on a mobile phone, he suddenly felt an abnormal headache, nausea, vomiting, and almost fainted. His parents quickly took him to the hospital.

After an MRI examination, the doctor discovered a pigeon egg sized tumor in Yang Yang's brain. The doctor actively developed a treatment plan and arranged for a tumor resection surgery for Yang Yang. Can playing with mobile phones often really trigger brain tumors?

• In 2011, the Environmental Epidemiology Research Center in Barcelona, Spain, pointed out that regular use of mobile phones would not increase the risk of brain tumors, while the risk of meningioma and Glioma in people who use mobile phones most would increase 2.01 times and 1.91 times respectively;
• In 2015, Swedish cancer expert Lennart Harder found that people who have been using mobile phones for more than 25 years have a three fold higher risk of developing glioma compared to those who have been using phones for less than a year. Starting using mobile phones before the age of 20 increases the risk of brain tumors.

Does that mean that mobile phones have radiation and can cause cancer? Not so. The Hierarchy of evidence of some current studies is limited,The causal relationship between mobile phone radiation and cancer has not yet been determined.

.CT examination, nuclear radiation, etc. belong to ionizing radiation.Radio waves, microwaves, etc. are non ionizing radiation.

And mobile phone radiation belongs to non ionizing radiation2B.

Some people say that 'charging and playing with a mobile phone increases radiation',But in fact, the strength of electromagnetic waves is not directly related to the battery level of the phone..

If you're really worried about phone radiation,It is recommended to place the phone 15 centimeters away from the body when sleeping.
