Looking for an oncologist's second opinion on Harper's juvenile arthritis

Harper was diagnosed with juvenile arthritis in July. The local team has recommended immediate surgery. We understand it's an important decision, and we'd like to be sure. We're asking if an oncologist - anywhere in the world - would be willing to review Harper's reports and give a short opinion (a call of 20 minutes or a written summary). We'd gladly pay for any cost to your practice that we can afford. We have scans, lab reports and the doctor's notes ready to share securely. We understand that you can't give formal medical advice without an examination, and we're simply looking for guidance on questions to ask and options to explore. Thanks for even thinking about it. Thank you for reading my story.
