In the midst of ongoing research, the U.S. Food and Drug Administration (FDA) is now saying that there is scientific evidence to suggest that cell phones do not pose a significant health risk as a result of radio frequency (RF) energy.
The announcement comes after the World Health Organization (WHO) released findings earlier this week to suggest that the long suspected link between cancer and cell phone use is false. The FDA is also citing a separate National Cancer Institute study that brain cancer did not significantly increase between 1987 and 2005, despite a significant rise in cell phone use nationally.
While cell phones can be sold without FDA clearance or approval, the agency reserves the right to monitor the effects they have on general health.
Results of Extensive Testing
The WHO study is the largest of its kind, and has been underway since 2000 in 13 countries. The study reported little to no risk of brain tumors as a result of long-term cell phone use; however experts still say some questions remain.
Abiy Desta, the network leader for science at the FDA's Center for Devices and Radiological Health said there are still some questions regarding radio frequency energy that are not yet fully answered. She added that the data would be very useful in assessing the future safety of mobile phone use.
The study focuses on four types of tumors found in tissues that most absorb RF energy emitted by cell phones: tumors of the brain known as glioma and meningioma, of the acoustic nerve, and of the parotid gland (the largest of the salivary glands).
The findings, which can be viewed in the June issue of International Journal of Epidemiology, revealed no significant evidence to suggest that RF energy and brain tumors were linked. While some of the data suggested an increased risk for people who use their devices heavily, the study's authors determined that biases and errors limit the strength of conclusions that can be drawn from it.
