Most people don't want to believe or listen to me when I talk about the negative effects of cell phone use and that's because the cell phone is such an integral part of our lives. If you can't see or feel the damage that is occurring to your brain than it must not be happening. I have had 3 patients die of Glioblastomas (brain tumors) and one patient had an Acoustic neuroma (Brain stem tumor). I'm a chiropractor not a medical doctor, so It should be extremely rare for me to ever have 1 patient with a Glioblastoma walk into my office. All of these patients lived on their cell phones. Studies have shown that in the last 10 years there has been an increase in brain tumors in adults and in children.
