%X In almost 90% of the cases of childhood leukemia, the etiology is unclear. A wide range of factors, including environmental, sociological, lifestyle influences are implicated as well as genetic susceptibility. The evidence is mixed as to whether (Electromagnetic Fields) EMFs can be responsible for direct DNA damage. DNA damage could arise as a result of persistently elevated free radical concentrations, caused by long-term EMF exposure. Some experiments have shown that EMFs affect these functions, though they have been difficult to reproduce and therefore remain controversial. The overall evidence is that magnetic fields induce changes in apoptosis (cell death). Changes in B lymphocytes can also change cellular division rates. A series of studies demonstrated EMF effects that made cells more likely to become cancerous. These findings may prove particularly important with regard to B-lineage (Acute Lymphocytic Leukemia) ALL. However, the original results have not yet been replicated, perhaps pointing to the need to tighten experimental protocols. In body, tissue free radicals are dangerous high-energy particles that damage cells and can both cause and accelerate the progression of cancer. Exposure to EMFs can increase the yield of free radicals by more than 60%, which could explain the diverse and often inconsistent nature of observed effects of EMFs, free radicals being intermediates in many natural processes. The hormone, melatonin is thought to protect the body from cancer by (a) neutralizing free radicals, (b) inhibiting the uptake of growth factors by cancer cells, (c) by increasing the likelihood of cancer cells undergoing apoptosis (cell death), and (d) by inhibiting the growth of blood vessels in tumors. The production of melatonin at night (when the majority of melatonin is produced by the body¡¯s pineal gland) was reduced significantly by light at night and magnetic fields associated with the electricity supply. It was found that melatonin protects cells from genetic damage
