testes, are particularly vulnerable to RF heating because there is relatively little blood
flow in them to carry away excess heat.
Research Results to Date: Is there a connection between RF and certain
health problems?
The results of most studies conducted to date say no. In addition, attempts to replicate
and confirm the few studies that have shown a connection have failed.
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
Interphone is the largest cell phone study to date, but it did not answer all questions
about cell phone safety. Additional research is being conducted around the world, and
the FDA continues to monitor developments in this field.
International Cohort Study on Mobile Phone Users (COSMOS)
The COSMOS study aims to conduct long-term health monitoring of a large group
of people to determine if there are any health issues linked to long-term exposure
to radio frequency energy from cell phone use. The COSMOS study will follow
approximately 300,000 adult cell phone users in Europe for 20 to 30 years.
