As public exposure to electromagnetic fields (EMFs) grows, there has been increasing concern about links between EMF radiation and cancer. The question at hand is whether small, low-frequency radiation emissions from cell phones, pagers, and other devices might be associated with cancer. To date, research in the area has been largely inconclusive pointing to the need for further study.

Is There a Link between EMF Exposure and Cancer?

To understand the proposed link between EMFs and cancer, it helps to understand a thing or two about the electromagnetic spectrum. First, it is important to recognize that the spectrum refers to the entire range of radiation energy. Thus, the term EMF is quite broad and can refer to low-frequency wavelengths such as those used in radios and very high-frequency wavelengths such as those found in nuclear power plants.

Second, although high-frequency EMF exposure has been well documented as being harmful for humans, the effects of low-frequency wavelengths are not well understood. When studies explore a relationship between EMF exposure and cancer, a primary issue pertains to how high the EMF levels are. Varying rates of exposure may account for the discrepant findings produced thus far.

In addition, research in this area is difficult because cancer is an illness that is both genetically and environmentally influenced. For example, a person may have a genetic loading for cancer, but they may make it worse via smoking and exposure to carcinogens. In order for research to establish a clear link between EMF exposure and cancer, scientists will need to conduct studies that account for pre-existing genetic risk as well as other environmental influences.
