HHS-OASH-2026-0397-0921 https://www.regulations.gov/comment/HHS-OASH-2026-0397-0921 My husband was diagnosed with Vestibular Schwannoma. When asking the doctor about if cell phone usage could be a contributing factor, since it is on his "cell phone ear" side, he stated that he could not confer, yet has seen a marked increase over the last 10 - 15 years. I happen to work with someone who had one removed about 8 years ago. Considering they used to be rare, we would very much like studies done to see if there is a correlation between device radiation and brain tumors.
