Hi and thank you so much for this query. I am so sorry to hear about this condition that your child has been diagnosed f. i understand this is no good news to him and his loved ones. I honestly hope we get to find a solution that would help him get out of this. There is no single best doctor that can address this condition. It would need coordinated services of various specialist including orthopedic surgeons, oncologist, radiation specialist, etc. My best suggestion is to get him in contact with an oncologist who would coordinate his care and direct him to see the other specialists as need arises. See the doctor you already know at Einstein and it would make a good start as to how to move forward. I hope this helps. I wish your son the best of possible outcomes. I encourage you and his loved ones to stand by him as he battles his way out of this. Also, feel free to ask us more questions if need be. Thanks so much for using our services. Dr Ditah, MD
