Adolescent and young adult oncology
Adolescent and young adult oncology is a branch of medicine that deals with the prevention, diagnosis, and treatment of cancer in adolescent and young adult (AYA) patients aged 16–40. Studies have continuously shown that while pediatric cancer survival rates have gone up, the survival rate for adolescents and young adults has remained stagnant.
