The scientific community at large therefore believes that the weight of scientific evidence does not
show an association between exposure to Radio Frequency (RF) from cell phones and adverse health
outcomes. Still the scientific community has supported additional research to address gaps in
knowledge. Some of these studies are described below.
Interphone Study
Interphone is a large international study designed to determine whether cell phones increase the risk
of head and neck cancer. A report published in the International Journal of Epidemiology (June, 2010)
compared cell phone usage for more than 5,000 people with brain tumors (glioma and meningioma)
and a similar number of healthy controls.
Results of this study did NOT show that cell phones caused brain cancer. In this study, most people
had no increased risk of brain cancer from using cell phones. For people with the heaviest use of cell
phones (an average of more than ½ hour per day, every day, for over 10 years) the study suggested a
slight increase in brain cancer. However, the authors determined that biases and errors prevented any
conclusions being drawn from this data. Additional information about Interphone can be found at
