A glioma is a type of malignant tumor that starts in the brain or spine. It is called a glioma because it arises from glial cells. https://en.wikipedia.org/
Glioblastoma Multiforme (GBM), a type of glioma, which is the most aggressive form of brain cancer, has increased in incidence (see below). It is the same type of cancer which killed Senator John Mc Cain, Ted Kennedy, Johnnie Cochran, and which has afflicted Maria Menounos' mother.
Myelin is the protective layer around nerve cells, analogous to the plastic coating insulating electrical wires.
Myelin is an outgrowth of a type of glial cell. https://en.wikipedia.
Damage to myelin causes neurological problems, such as numbness, paraethesia (prickling and burning sensations), headaches, memory and concentration impairment, irritability, anxiety, and confusion (including among children). These are also symptoms in electrohypersensitivity, or EHS.
Demyelination occurs in diseases like multiple sclerosis.
Malignant schwannoma is a very rare type of cancer in the Schwann cells, also a type of glial cell https://en.wikipedia.org/
Gliomas Now Most Common Cancer in 15-19 year olds, Increasing Worldwide
Forecast for 2019-2025 shows an "Increase in prevalence of brain tumours (According to U.S. National Cancer Institute (NCI) glioblastoma multiforme is considered as the most aggressive form of brain cancer with 15.4% of all primary brain tumours and about 60% – 75% of all astrocytoma) driving the growth of glioblastoma multiforme treatment market. North America dominates the glioblastoma multiforme treatment market .. North America region growth is attributed to increase in the prevalence of glioblastoma multiforme disease (According to Centres for Disease Control and Prevention (CDC), in 2011, approximately 22,000 adults in the U.S. were diagnosed with primary malignant tumours of the brain and spinal cord out of which gliomas accounted for the highest rate of incidence)" https://
A report published in 2015 in the journal Neuro-Oncology finds that gliomas are the most common cause of cancer-related deaths in adolescents and young adults aged 15-39 and the most common cancer occurring among 15-19 year olds (see p. 18 of study http://neuro-oncology.
GBM has increased according to studies from around the world, with the highest increases in the frontal and temporal lobes https://www.saferemr.

4 Studies: Wireless radiation causing gliomas, Schwannomas, myelin damage
1) The US government National Toxicology Program's $30 million study showed that 3% of rats that were exposed to cell phone radiation developed gliomas, whereas rats that were not exposed did NOT develop gliomas. The rats also developed malignant Schwannomas. Results were statistically significant - it's preliminary May 2016 report here http://biorxiv.org/
In November 2018, the NTP published its cell phone safety sheet based on its study. It states: https://www.niehs.nih.
- Clear evidence of tumors in the hearts of male rats. The tumors were malignant schwannomas.
- Some evidence of tumors in the brains of male rats. The tumors were malignant gliomas.
2) Kim, Ju Hwan, et al. “Long-term exposure to 835 MHz RF-EMF induces hyperactivity, autophagy and demyelination in the cortical neurons of mice.” Scientific Reports, vol. 7, no. 41129, 2017.
found that RF-EMF exposure led to myelin sheath damage and hyperactivity-like behaviour in mice exposed to 835 MHz RF-EMF at a specific absorption rate (SAR) of 4.0 W/kg for 5 hours/day during 12 weeks. Demyelination was induced in cortical neurons following prolonged RF-EMF exposure and suggests a potential cause of neurological or neurobehavioural disorders.
"considers the evidence for an association between myelin integrity and exposure to low-intensity radiofrequency electromagnetic fields (RF-EMFs)
Overall, evidence from in vivo and in vitro and epidemiological studies suggests an association between RF-EMF exposure and either myelin deterioration or a direct impact on neuronal conduction, which may account for many electrohypersensitivity symptoms. The most vulnerable are likely to be those in utero through to at least mid-teen years, as well as ill and elderly individuals."

4) Johansson O, Redmayne M, “Exacerbation of demyelinating syndrome after exposure to wireless modem with public hotspot”, Electromagn Biol Med 2016, 29:1-5
This is a case study of a Colorado woman who experienced a return of her demyelination symptoms (seizures, vertigo, headaches, sleeping problems) following exposure to her neighbor's (Xfinity) Home Wi-Fi Modem with Public Hotspot in August 2014.
After her neighbor replaced the modem with one without the hotspot feature, the seizures stopped immediately, and the other symptoms faded gradually, after which she was fine and
again could sleep well. Later, when another neighbor obtained the same modem with activated hotspot, her symptoms returned.
A possible association between electrohypersensitivity, myelin integrity and exposure to low-intensity radiofrequency electromagnetic fields (RF-EMF) has recently been proposed. Since the West Nile virus attacks both the nerve cells and the glial ones, one explanation to the above observed case effects is that the initial virus attack and the wireless modem’s RF-EMF affect the nervous system through the very same, or similar, avenues, and maybe both via the oligodendrocytes

Xfinity Wi-Fi routers with public hot spot
(if you are a Comcast/Xfinity customer, you probably have a modem with a public hotspot feature since this equipment became their standard issue in 2014. Xfinity's home wireless gateway modems have 2 lines of Wi-Fi - one for your household use, and another for public hotspot use - use of one does not affect speeds/capacity of the other, and there are no security issues since they are separate lines. However, you are paying for the power to supply wi-fi to the public hotspot range of 100m around your modem and you are exposing yourself to much higher wireless radiation levels with a public hotspot on your router, Here's more info. about the home hotspot feature and a video that explains it, and a link to disable the public hotspot feature on your Xfinity modem. http://wifi.xfinity.com/ In April 2017, xfinity launched its nationwide mobile service which depends on the public wi-fi hot spots in these modems. You will know if you are within range of an Xfinity hot spot if your smartphone/ipad/laptop shows that there is "xfinitywifi" available in the list of wireless networks. Disabling the Wi-Fi hot spot requires a separate procedure from disabling the Wi-Fi for your household use on the modem. To turn off the Wi-Fi for your household use, such as when you go to sleep at night, type in 10.0.0.1 in your browser window. login (user: admin), select connection, select wi-fi, select edit, select disable (to turn back on, do the same thing, but in the last step, select enable) )
Gliomas Increasing Worldwide - Data from England, US, Netherlands
- In a study done in England looking at GBMs from 1995-2015 https://www.hindawi.com/
journals/jeph/2018/7910754/ fr ontal lobe GBM increased from 533 to 1231, statistically significant increase in primary GBM tumours were seen, especially in frontal and temporal lobes of the brain.temporal lobe GBM increased from 334 to 994. The increase was attributed to an environmental factor

- In the US, The National Cancer Institute reported that glioma incidence in the frontal lobe increased among young adults 20-29 years of age (Inskip et al., 2010). The incidence of glioblastoma multiforme (GBM), which accounts for about half of all gliomas, increased in the frontal and temporal lobes, and in the cerebellum among adults in the U.S. from 1992-2006 (Zada et al., 2012).
- data from The Netherlands. The black segment of each column tracks the incidence of glioblastoma multiforme (GBM), the most aggressive and deadly type of brain tumors. While the total incidence of all types of brain tumors in The Netherlands rose at the rate of only about 0.7% per year, the increase in GBM was about 3.1% per year —that is, the incidence more than doubled over the period 1989-2010. (Follow the thin red line we superimposed on the histogram to track the trend.) This is a statistically significant increase. At the same time, the rate of all the other types of brain tumors went down; these changes are also significant. The higher incidence of GBMs is being masked by the lower rates of the other types of brain cancer.

Risk of glioma from cell phone and cordless phone use
Three independent, case-control studies have found that long-term use of cell phones increases risk for glioma (Interphone Study Group, 2010; Hardell et al, 2013; Coureau et al, 2014). The only research to examine cordless phone use also found increased glioma risk with long-term use (Hardell et al, 2013). These studies include data from 13 nations: Australia, Canada, Denmark, Finland, France, Germany, Israel, Italy, Japan, New Zealand, Norway, Sweden and the UK. After ten years of wireless phone use (i.e., cell phone plus cordless phone use), the risk of glioma doubles and after 25 years, the risk triples (Hardell et al, 2013).
