Most scientists feel that electromagnetic fields do not increase a person's risk for cancer, but two recent studies show that they may. During the night, your brain produces large amounts of a hormone called melatonin that is a potent antioxidant which may help to prevent cancer. As people age, brain levels of melatonin drop. A study from Quebec shows that people who live near electromagnetic power lines have a greater drop of melatonin with aging than those who do not live near them.

Your brain is supposed to increase its production of melatonin each night. A study from Seattle shows that people who live in houses that have high levels of electromagnetic waves have lower than normal rises in melatonin each night. These results suggest that exposure to nighttime residential 60-Hz magnetic fields can depress the normal nocturnal rise in melatonin. So far, no one has done convincing studies to show that electromagnetic waves cause cancer, but these studies raise enough question for further studies to be done.
