Looking for a pediatric cardiologist's second opinion on Ali's a suspicious lymph node biopsy

Ali was diagnosed with a suspicious lymph node biopsy in April. 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 Ali'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 so much.
