Cell Phones Causes Brain Tumor (Acoustic Neuroma)

In 2004, there was a Swedish study published in the International Journal of Epidemiology where researchers found that the risk of developing a benign brain tumor called an acoustic neuroma was almost double for those who started to use phones before their diagnosis. In addition, the tumor risk was almost four times higher on the side of the head where the phone was held.

An acoustic neuroma is a benign tumor that causes symptoms or ringing of the ears (tinnitus) as well as hearing loss.

Of note, all 750 test subjects had been using cell phones for at least 10 years, nearly all using the early analog models that emit more electromagnetic radiation than the digital models now on the market.
