Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. The present study used a diathermy model – the therapeutic application of non-ionizing radiation – on laboratory rats subjected to maximum exposure non-ionizing radiation (30 min, 10 times in two weeks) in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue.Ninety minutes after radiation with the highest SAR, the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis.
Studies have shown an association between cell phone use and a decreased risk of certain brain tumors. According to a peer-reviewed Dec. 2006 study of 420,095 cell phone users in Denmark, the results showed a "reduced brain tumor risk" among long-term subscribers.  Two other peer-reviewed studies also found that cell phone users had a slightly decreased risk of developing brain tumors. A July 20, 2005 Danish study  found a "decreased risk for high-grade glioma," a malignant brain tumor, and a 2005 Swedish study  also found a "decreased odds ratio" for developing glioma as well as meningioma, another type of brain tumor.
I’ve started to shut off my WIFI from midnight until about sundown the next day. The results have been astounding. I’ve been having serious joint aches and I’m not THAT old. Enough that it was hampering my quality of life. So I did an experiment. I turned off my WIFI router and took out the battery. Been doing this now for 2 days and I’m telling you I’m a new woman. I’m a little stiff getting out of bed in the morning but nothing like I was.
Thus far, the data from studies in children with cancer do not support this theory. The first published analysis came from a large case–control study called CEFALO, which was conducted in Denmark, Sweden, Norway, and Switzerland. The study included children who were diagnosed with brain tumors between 2004 and 2008, when their ages ranged from 7 to 19 years. Researchers did not find an association between cell phone use and brain tumor risk either by time since initiation of use, amount of use, or by the location of the tumor (21).
The industry’s $4.7 million contribution to the WHO appears to have had its most telling effect in May 2011, when the WHO convened scientists in Lyon, France, to discuss how to classify the cancer risk posed by cell phones. The industry not only secured “observer” status at Lyon for three of its trade associations; it placed two industry-funded experts on the working group that would debate the classification, as well as additional experts among the “invited specialists” who advised the group.38

A series of studies testing different scenarios (called simulations by the study authors) were carried out using incidence data from the Nordic countries to determine the likelihood of detecting various levels of risk as reported in studies of cell phone use and brain tumors between 1979 and 2008. The results were compatible with no increased risks from cell phones, as reported by most epidemiologic studies. The findings did suggest that the increase reported among the subset of heaviest regular users in the Interphone study could not be ruled out but was unlikely. The highly increased risks reported in the Swedish pooled analysis were strongly inconsistent with the observed glioma rates in the Nordic countries (24).
George Carlo seemed like a good bet to fulfill Wheeler’s mission. He was an epidemiologist who also had a law degree, and he’d conducted studies for other controversial industries. After a study funded by Dow Corning, Carlo had declared that breast implants posed only minimal health risks. With chemical-industry funding, he had concluded that low levels of dioxin, the chemical behind the Agent Orange scandal, were not dangerous. In 1995, Carlo began directing the industry-financed Wireless Technology Research project (WTR), whose eventual budget of $28.5 million made it the best-funded investigation of cell-phone safety to date.4
Studies by five independent research groups regarding cell phones and brain tumors have revealed significantly increased risks of a benign tumour of the cranial nerve supplying the ear. This grows slowly and must be removed in a major operation that can result in permanent facial paralysis. Other risks found were cancer of the glial cells (including neurons) of the nervous system and cancer of the meninges, the membrane covering the brain and spinal cord.
