Doctors, could you help? Savannah's a suspicious lymph node biopsy

Savannah was diagnosed with a suspicious lymph node biopsy in November. The local team has recommended an experimental drug. We understand it's an important decision, and we'd like to be sure. We're asking if a pediatric cardiologist - anywhere in the world - would be willing to review Savannah'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. Thanks for being kind about this.
