For female breast cancer, some early epidemiological studies suggested a risk for magnetic fields.
Then, in the early 2000s, three large and well-conducted studies of residential exposure were published, with uniformly negative findings. Two large studies of occupational exposure were also largely negative.
This led authorittative review groups to conclude that we could now have some confidence that magnetic fields do not cause breast cancer.
