While there is no consensus, especially in the US, about the safety/risks of our chronic exposures to low frequency EMFs (like from cell phones), this developing story shares patterns with those of cigarette smoking, secondhand smoke, lead, asbestos, and chemical flame retardants. Some experts believe the science proves that we are already experiencing threatening risks. Some are not yet convinced. And debate will continue for decades to come.
In the video in the next section, Dr. Sanjay Gupta does an excellent segment commenting on the developing science on whether cell phone radiation, a contributor to EMFs, may cause cancer. The segment highlights key issues when studying the safety of cell phone radiation. Remember though that settling the question of whether cell phone radiation causes brain cancer is just one among many unanswered questions about the health risks from our many EMF sources.
