Pediatric Hematology Oncology is a pediatric subspecialty with an emphasis on treating children who are suffering from a blood disease or condition, especially cancer. The doctors who become pediatric hematologists and oncologists must go through rigorous medical training to properly treat and diagnose children with these conditions. As highly trained doctors, they can provide the necessary care to children who are seriously ill or at risk of developing blood problems.

A Physician Assistant is a medical professional who works with a team of other doctors to diagnose and treat a variety of illnesses and health disorders. They are legally licensed to practice medicine, though they do not go through the same rigorous schooling as doctors. However, these professionals are more than able to help patients with most medical conditions, and they work alongside doctors to ensure they can give adequate care to their patients.
