Breaks disrupt cell functions, changes genes, causes cancer and cell death. Single strand breaks may repair, but double strand breaks may not repair. Animals exposed for 2 hours to 1-5 gauss have more single strand DNA breaks. Breaks increase when the animal is given drugs and exposed to radiation. Exposure to magnetic fields causes melatonin to disappear.
Free radicals promote rather than mitigate cancer.
Cancer cells express more transferrin receptors and also pick up more iron in the presence of magnetic fields. Within 4 days isolated cells increased apoptosis. Calcium ion concentration increased when EMFs were introduced into the cell causing intracellular calcium buildup and apoptosis. One reason experiments may not be replicated is because experimenters do not understand all the factions at work in the cell. Also, cells saturated in serum showed a greater effect in the presence of magnetic fields than cells with little or no serum saturation.
