Can a pediatric cardiologist review Raúl's scans?

Raúl was diagnosed with a suspicious lymph node biopsy in August. The local team has recommended watchful waiting. 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 Raúl'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. Please ask me anything in the questions section. I'll answer honestly and quickly.
