Dear Friend. Hi, I am Chat Doctor, I have read your query in detail, I understand your concern. I feel that requires evaluation, that swelling can arise from bone, or it can be soft tissue swelling. You should get her a X-ray Chest, Ultrasound of that area, and if required a FNAC or Biopsy might be required. This is my personal opinion based on details available here.  If you want to discuss your issues further, you may please ask stay Healthy. Chat Doctor, MD
