HHS-OASH-2026-0397-3440 https://www.regulations.gov/comment/HHS-OASH-2026-0397-3440 Diagnosed with a Giant Cell Tumor in 2023 at my distal right femoral condyle approximately 3 cm spherical bone mass. I had been carrying my cell phone in my right pants leg pocket that ended approximately 5 cm from the where the tumor was discovered. I have been healthy to date. Got the Johnson & Johnson Covid shot in 2021 as forced to keep my job. Is the tumor coincidence or is there a cause and effect? I’m 65 years old. Giant Cell Tumors typically are limited to younger people.
