HHS-OASH-2026-0397-4243 https://www.regulations.gov/comment/HHS-OASH-2026-0397-4243 Dear U.S. Government, My brother got a brain tumor from his cellphone out of nowhere., I have no proof, but I believe it's more than a coincidence that it was on the same side of his head where he always held his cellphone. He spent many hours on his cellphone building his land development business. We have no family history whatsoever of brain tumors either. He lost everything and now lives in a nursing home. EMF and wireless radiation should be shielded from the public. Sincerely, BP
