ANALYSIS OF RECENT STUDIES
Advice from University of Pittsburgh Cancer Institute Based on Advice from an International Expert Panel
Electromagnetic fields generated by cell phones should be considered a potential human health risk. Sufficient time has not elapsed in order for us to have conclusive data on the biological effects of cell phones and other cordless phones—a technology that is now universal.
Studies in humans do not indicate that cell phones are safe, nor do they yet clearly show that they are dangerous. But, growing evidence indicates that we should reduce exposures, while research continues on this important question.
Manufacturers report that cell and wireless phones emit electromagnetic radiation. Electromagnetic fields are likely to penetrate the brain of children more deeply than adults. Modeling in the diagram below estimate that young children are more susceptible to electromagnetic fields due to smaller sized brains and softer brain tissue.
1) Electromagnetic fields from cell phones are estimated to penetrate the brain especially in children. (Figure 1.)

2) Living tissue is vulnerable to electromagnetic fields within the frequency bands used by cell phones (from 800 to 2200 MHz) even below the threshold of power imposed by most safety standards ( 1.6 W/Kg for 1g of tissue), notably an increase in the permeability of the blood-brain barrier and an increased synthesis of stress proteins.
The most recent studies, which include subjects with a history of cell phone usage for a duration of at least 10 years, show a possible association between certain benign tumors (acoustic neuromas) and some brain cancers on the side the device is used. [more]
