According to a Mar. 2008 meta-analysis of cell phone studies there is a "consistent pattern" connecting cell phone use and an increased risk of developing glioma, a type of brain tumor.  A Mar. 31, 2009 study found that long term cell phone use (10 years +) "approximately doubles the risk" of being diagnosed with glioma on the same side of the head where the cell phone is held.  In Apr. 2013 another study of Swedish cell phone users also found an association between cell phone use and the development of glioma and acoustic neuroma - a benign tumor formation on the nerve near the ear.  That study’s conclusions were confirmed by a different study in Apr. 2014.  Other studies published from 2005-2013 have similarly concluded that there is an association between cell phone use and increased risk of developing brain and head tumors.    
I am 60 years old, single. I got a tumor on my left breast when I took a bath on Sunday, Sep. 4th. I came to HCM City Medic Hoa Hao Clinic on Sep. 5th for an X-ray then a biopsy test. In the afternoon I came back to have the result, my case fell as ‘invasive ductal carcinoma. Then I came to Ho Chi Minh City Oncology Hospital on September 7th for some more tests: blood, urine, X-ray, mammogram, ECG. Can I drink ‘Ensure Original nutrition shake’ as my students offer me 12 bottles (8 FL oz /237 mL), I am looking forward to your soonest consideration.
No, it isn’t. It is true that International Agency for Research on Cancer (part of the World Health Organisation) has classified radiofrequency electromagnetic fields, including radiofrequency electromagnetic fields from wireless phones as ‘2b’ in its monographs on the evaluation of carcinogenic risks to humans. But that’s by no means proof of danger. You see 2b is ‘possibly carcinogenic’ and as well as Wi-Fi, the category includes coffee, carpentry and pickled vegetables. Some evidence has to be present (except when insufficient evidence is accepted) but the case does not have to be proven.
Participation bias, which can happen when people who are diagnosed with brain tumors are more likely than healthy people (known as controls) to enroll in a research study. Also, controls who did not or rarely used cell phones were less likely to participate in the Interphone study than controls who used cell phones regularly. For example, the Interphone study reported participation rates of 78% for meningioma patients (range among the individual studies 56–92%), 64% for glioma patients (range 36–92%), and 53% for control subjects (range 42–74%) (6).
The possible effects of RF-EMR due to cellular phone and Wi-Fi usage should be investigated by researchers in more detail because the harmful effects should be proven instead of just implying the possible detrimental effects. Our findings display contrast results when we compared them with existing information and beliefs. We have not seen any difference between sperm parameters and cell phone and wireless internet usage. Larger population based studies combined with the laboratory results are needed to reach a definitive conclusion.
I am shin datuin..a radiologic technologist..I never thought that electromagnetic radiation is harmful to our health because according to our studies.. EMR is safe (example:radiation of MRI..wifi..) I became hypersensitive to EMR after using the USB modem (the 4G internet)..Because when you download a file.. the EMR of 4G internet/USB modem boost it’s signal capacity/transmission rate and damages your cells in the body specifically to the brain.. 16 hours or above of downloading will break your immune system to electromagnetic radiation (maybe it varies on your body size)..But after the 16 hours of exposure.. my body inhibits the symptoms of feeling tired.. headache.. dizziness..nausea..fast heartbeat..I felt like someone is touching at the back of my head (occipital region).. So i shut off the USB modem and the symptoms were gone after few hours of rest.. But even now.. i’m having this problem when i’m at the High EMR areas.. so i minimize using our wifi router.. Anyway.. wifi signal or transmission can be setup to minimum capacity..So set it up before it’s too late.. Be safe guys!
Also of note, in a study by Henrietta Nittby et al (2009), the lowest exposure SARs were worse than the higher SAR exposures. Some scientists consider blood brain barrier effects at these very low levels of radiation exposure (i.e. 30-45x lower than the ‘Top 10’ lowest SAR phones ranked by the Environmental Working Group) to be of equal or even greater concern for the population than the increase in brain tumors from cell phone use that is expected.
I used to have an iPhone (see Why I Got Rid of My Smartphone) and discovered that no case kept the radiation from emitting. I tried the Pong Case, the Otterbox, and an RF Safe Pouch. The pouch by far was the most effective. The Pong Case was better than the Otterbox, but still showed higher levels than I would like to see. You’ll see the various levels in the video below.
Mobile phones and Wi-Fi radiofrequency radiation are among the main sources of the exposure of the general population to radiofrequency electromagnetic fields (RF-EMF). Previous studies have shown that exposure of microorganisms to RF-EMFs can be associated with a wide spectrum of changes ranged from the modified bacterial growth to the alterations of the pattern of antibiotic resistance. Our laboratory at the nonionizing department of the Ionizing and Non-ionizing Radiation Protection Research Center has performed experiments on the health effects of exposure to animal models and humans to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons, magnetic resonance imaging, and Helmholtz coils. On the other hand, we have previously studied different aspects of the challenging issue of the ionizing or nonionizing radiation-induced alterations in the susceptibility of microorganisms to antibiotics. In this study, we assessed if the exposure to 900 MHz GSM mobile phone radiation and 2.4 GHz radiofrequency radiation emitted from common Wi-Fi routers alters the susceptibility of microorganisms to different antibiotics. The pure cultures of Listeria monocytogenes and Escherichia coli were exposed to RF-EMFs generated either by a GSM 900 MHz mobile phone simulator and a common 2.4 GHz Wi-Fi router. It is also shown that exposure to RF-EMFs within a narrow level of irradiation (an exposure window) makes microorganisms resistant to antibiotics. This adaptive phenomenon and its potential threats to human health should be further investigated in future experiments. Altogether, the findings of this study showed that exposure to Wi-Fi and RF simulator radiation can significantly alter the inhibition zone diameters and growth rate for L monocytogenes and E coli. These findings may have implications for the management of serious infectious diseases.
In a separate study by the same Swedish team, they found more than seven times the risk among people using a cell phone more than 20 years and 6.5 times the risk for long-term users of cordless phones. As expected, most of the gliomas and acoustic neuromas were on the same side of the head, which was usually exposed to the phone. In the 2013 official report on the medical evidence for brain tumors, the International Agency for Research on Cancer concluded that radiation from cell phones is “possibly carcinogenic to humans”.
