RF-EMF emissions from wireless phones are class 1 human carcinogens
"Using the long-established and respected Bradford Hill criteria for assessing causality, this paper shows that RF-EMF exposure from mobile (and cordless) phones should be regarded as an IARC class 1 human carcinogen (cancer causing agent). Current guidelines for exposure need to be urgently revised. . .
Case-control study of the association between malignant brain tumours diagnosed between 2007 and 2009 and mobile and cordless phone use
"This new study confirms previous results of an association between mobile and cordless phone use and malignant brain tumours. The findings provide support for the hypothesis that RF-EMFs play a role both in the initiation and promotion stages of carcinogenesis. . .

Look at the table of EHS studies in this EMF Portal database. It shows what the difficulty is in finding what causes EHS. Some of the studies listed in the table are cohort studies. Their reliability is questionable because of the lack of control populations. Everywhere we all are exposed to wireless communication-emitted radiation. Since we do not know what might be the level of exposure that triggers EHS symptoms it is not possible to determine who can serve as control cohort. Furthermore, besides a diverse number of EMF sources in our environment, there is an even more diverse number of other environmental stressors that lead to serious bias in evaluation of the results. . . .
Stephen Genuis and Christopher Lipp (2011)
As the prevalence of wireless telecommunication escalates throughout the world, health professionals are faced with the challenge of patients who report symptoms they claim are connected with exposure to some frequencies of electromagnetic radiation (EMR). Some scientists and clinicians acknowledge the phenomenon of hypersensitivity to EMR resulting from common exposures such as wireless systems and electrical devices in the home or workplace; others suggest that electromagnetic hypersensitivity (EHS) is psychosomatic or fictitious. Various organizations including the World Health Organization as well as some nation states are carefully exploring this clinical phenomenon in order to better explain the rising prevalence of non-specific, multi-system, often debilitating symptoms associated with non-ionizing EMR exposure. As well as an assortment of physiological complaints, patients diagnosed with EHS also report profound social and personal challenges, impairing their ability to function normally in society.
This paper offers a review of the sparse literature on this perplexing condition and a discussion of the controversy surrounding the legitimacy of the EHS diagnosis. Recommendations are provided to assist health professionals in caring for individuals complaining of EHS.

Interview with Olle Johansson, Ph.D. and Neuroscientist at the Karolinska Institute in Stockholm. Co-author of the Bioinitiative Report and therefore one of the foremost authorities on electromagnetic fields and health effects, with more than 30 years of research behind him.

BACKGROUND: Handheld mobile phones (MPHs) have become a 'cultural' accessory device, no less so than a wrist watch. Nevertheless, the use of MPHs has given rise to great concern because of possible adverse health effects from exposure to the radiofrequency radiation (RFR) emitted by the device. Previous studies suggested correlation between MPH and salivary gland tumors.
OBJECTIVE: To evaluate whether MPH induces physiologic changes in the adjacent parotid gland, located on the dominant side, in terms of secretion rates and protein levels in the secreted saliva.
MATERIALS AND METHOD: Stimulated parotid saliva was collected simultaneously from both glands in 50 healthy volunteers whose MPH use was on a dominant side of the head.
RESULTS: A significantly higher saliva secretion rate was noticed in the dominant MPH side compared with that in the non-dominant side. Lower total protein concentration was obtained in the dominant compared with the non-dominant MPH side among the right dominant MPH users.
CONCLUSIONS: Parotid glands adjacent to handheld MPH in use respond by elevated salivary rates and decreased protein secretion reflecting the continuous insult to the glands. This phenomenon should be revealed to the worldwide population and further exploration by means of large-scale longitudinal studies is warranted. . . .
Live Blood and Electrosmog - Dr. Magda Havas (first posted March, 2010)
Live blood cell analysis, in its simplest form (i.e. examining the size, shape, and clumping of cells) may reveal information about electrohypersensitivity that doctors could use in their clinics, and that scientists could use in addition to questionnaires and other types of testing.

Hints for a Shared Pathophysiology?
Background: Tinnitus is a frequent condition with high morbidity and impairment in quality of life. The pathophysiology is still incompletely understood. Electromagnetic fields are discussed to be involved in the multi-factorial pathogenesis of tinnitus, but data proofing this relationship are very limited. Potential health hazards of electromagnetic fields (EMF) have been under discussion for long. Especially, individuals claiming themselves to be electromagnetic hypersensitive suffer from a variety of unspecific symptoms, which they attribute to EMF-exposure. The aim of the study was to elucidate the relationship between EMF-exposure, electromagnetic hypersensitivity and tinnitus using a case-control design.
Methodology: Tinnitus occurrence and tinnitus severity were assessed by questionnaires in 89 electromagnetic hypersensitive patients and 107 controls matched for age-, gender, living surroundings and workplace. Using a logistic regression approach, potential risk factors for the development of tinnitus were evaluated.
Findings: Tinnitus was significantly more frequent in the electromagnetic hypersensitive group (50.72% vs. 17.5%) whereas tinnitus duration and severity did not differ between groups. Electromagnetic hypersensitivity and tinnitus were independent risk factors for sleep disturbances. However, measures of individual EMF-exposure like e.g. cell phone use did not show any association with tinnitus.
Conclusions: Our data indicate that tinnitus is associated with subjective electromagnetic hypersensitivity. An individual vulnerability probably due to an over activated cortical distress network seems to be responsible for, both, electromagnetic hypersensitivity and tinnitus. Hence, therapeutic efforts should focus on treatment strategies (e.g. cognitive behavioral therapy) aiming at normalizing this dysfunctional distress network. . . .
Objective: We sought direct evidence that acute exposure to environmental-strength electromagnetic fields could induce somatic reactions (EMF hypersensitivity).
Methods: The subject, a female physician self-diagnosed with EMF hypersensitivity, was exposed to an average (over the head) 60-Hz electric field of 300 V/m (comparable to typical environmental-strength EMFs) during controlled provocation and behavioral studies.
Results: In a double-blinded EMF provocation procedure specifically designed to minimize unintentional sensory cues, the subject developed temporal pain, headache, muscle-twitching, and skipped heartbeats within 100 s after initiation of EMF exposure (P < 0.05). The symptoms were caused primarily by field transitions (off-on, on-off) rather than the presence of the field, as assessed by comparing the frequency and severity of the effects of pulsed and continuous fields in relation to sham exposure. The subject had no conscious perception of the field as judged by her inability to report its presence more often than in the sham control.
Discussion: The subject demonstrated statistically reliable somatic reactions in response to exposure to subliminal EMFs under conditions that reasonably excluded a causative role for psychological processes.
Conclusion: EMF hypersensitivity can occur as a bona fide environmentally-inducible neurological syndrome.
Pilot Study 2008 - Increased Concentrations of Certain Persistent Organic Pollutants in Subjects with Self-Reported Electromagnetic Hypersensitivity - Hardell, Carlberg, Soderqvist, Hardell, Bjornfoth, Bavel and Lindstrom
"A number of persons report a variety of health problems related to exposure to electromagnetic fields (EMF)or being close to electrical equipment. These symptoms have been grouped together as electromagnetic hypersensitivity (EHS). The prevalence has been reported to 5% in Switzerland, in Sweden and in California. Reactions typically include a wide range of non specific symptoms that afflicted individuals attribute to exposure to EMF. . .
