evidence: What I learned really surprised me. The RF Radiation emitted by Bluetooth Headsets does cause brain tumors. Scientific studies show that there has been an increase in cancer in the temporal lobe of the brain since people started using cell phones and Bluetooth headphones. [...] Likewise in the article "Do Bluetooth Headphones Cause Cancer?" the medical website verywellhealth.com discusses this topic. At least this article acknowledges many of the health problems the independently funded scientific studies find, but then they spend the rest of the article down playing those findings. I have read the findings. As I describe above they linked serious illness to RF Radiation. It is not something to be downplayed or taken lightly. [...] Okay. So all this disruption in the flow of the brain, what does it really mean? According to Dr. Andrew Goldsworthy, an leading researcher and doctor in the biological effects of radiation, it can mean an increased risk of cancer, ADHD, headaches, depression and tinnitus. Now, that’s scary stuff. Let’s take a closer look at the correlation between Bluetooth headset use and tumors/cancer. "Short wavelengths, as well as the rapid rise and fall of the pulses emitted by Bluetooth and cell phones, can damage human cells by throwing off calcium ion signaling and causing ion channels to leak. The cellular disruption can cause irreparable DNA damage, which can increase cancer risk," said Dr. Andrew Goldsworthy.
