My daughter in law was diagnosed with spindle cell sarcoma 1 year ago. A small cyst looking lump was removed from her upper arm. Margins were clear. She underwent 6 weeks of radiation. All went well. We are now at her 1 year follow up. She had a chest CT yesterday that said, “sclerotic focus 1.8cm in anterolateral aspect third rib” but also stated “no new osseous lesion identified”. Is this good or bad news?
