"Newly diagnosed cancers were significantly higher among those who had lived for 10 years within 400 metres of the mast, in operation since 1993, compared with those living further away, and the patients had fallen ill on average 8 years earlier. People living within 400 metres of the mast in Naila had three times the risk of developing cancer than those living further away. This semms to be an undeniable clustering of cancer cases."
"These recent studies, using the exposure methods and the cut-off levels set a priori, each concluded that there was little evidence of any association. The pooled analyses, using different exposure measures and different cut-offs, conclude that an association exists at high exposure levels. It is not clear if the results of the pooled analysis are more valid than those of the recent major studies, although this has been often assumed in influential reviews."
Oxidative Stress and Apoptosis in Relation to Exposure to Magnetic Field

"This study supports the idea that the aetiological basis of facial skin symptoms among VDT-workers includes physical as well as psychosocial factors, and that the interaction between such factors might be significant in the understanding of skin complaints among VDT workers."
"The pooled RR from studies in women was 1.12 (95% CI: 1.09, 1.15), but variations between the contributing results are not easily attributable to chance (P = 0.0365). A fairly homogeneous increased risk was found for men (a pooled RR of 1.37, with 95% confidence limits of 1.11, 1.71, and homogeneity P-value = 0.1101). However, in both genders, results from individual studies are very variable and in part contradictory. The paramount methodological problem inhibiting valid conclusions about an association between EMF and breast cancer is the probable misclassification of exposure and the possible misclassification of the disease itself."
"There were severe degenerative changes, shrunken cytoplasm and extensively dark pyknotic nuclei and less neuron in the EMR groups compared to control groups. The most affected EMR group was the 2450 MHz group. In the frontal cortex and brain stem of the EMR groups, caspase-3 immunoreactivity was increased compared to the control group. The most affected group was again the 2450 MHz group. CONCLUSION: EMR causes to structural changes in the frontal cortex, brain stem and cerebellum and impair the oxidative stress and inflammatory cytokine system. This deterioration can cause to disease including loss of these areas function and cancer development."
"This study showed significant decrease in volunteers' ACTH, cortisol, thyroid hormones, prolactin for young females, and testosterone levels."
"The results of our study showed that RF radiation affects cell morphology, increases SCE and inhibits cell proliferation. However, EGb 761 has a protective role against RF induced mutagenity. We concluded that RF radiation induces chromosomal damage in hPBLs but this damage may be reduced by EGb 761 pre-treatment."
"More precisely, our results demonstrate that aspects of the induced but not the evoked brain activity during PEMF exposure can be different from those not influenced by PEMF radiation. This effect appears in higher frequency bands when subjects process task-relevant target stimuli but was not present for irrelevant standard stimuli. As the induced brain activity in higher frequency bands has been proposed to be a correlate of coherent high-frequency neuronal activity, PEMF exposure may provide means to systematically alter the pattern fluctuations in neural mass activity."
