HHS-OASH-2026-0397-0457 https://www.regulations.gov/comment/HHS-OASH-2026-0397-0457 I strongly suggest that my son died from EMF exposure from using an early model cell phone. His brain cancer tumor (glioblastoma) was shaped like a cone with its originating tip adjacent to his right ear. This was an earlier cell phone used approximately 2015 - 2018, when the cell phone transmitter was located adjacent to the right ear. Who was a young man, very socially connected, who always had his cell phone up to his ear while talking to his friends.
