Is There an EMF-Cancer Connection?

Scientists would also like to understand the biological processes by which EMF exposure might lead to cancer. Laboratory investigations have shown that EMFs can indeed elicit some effects in cells, including changes in hormone levels, in protein synthesis, and in ion flow across cell membranes. But so far this research has not produced clear laboratory evidence that EMFs either cause or promote cancer. Without such evidence, most researchers are reluctant to pin the carcinogen label on EMFs based on the somewhat ambiguous epidemiology studies. What is needed, researchers say, is more research, and that is coming. Two or three epidemiological studies, are scheduled to be released in the next couple of months, and several large projects are under way which won't be finished for 2 or 3 years. This next generation of research will include several improvements over its predecessors. The studies will in general be much larger - large enough to provide some real statistical power - and they will take into account what researchers have learned in the past few years about measuring EMF exposures.
