Adolescents and young adults (AYAs) with cancer are a unique patient population in oncology. To better understand the current landscape of AYA cancer, an opt-in, secure online survey was offered to a general population of AYA patients and survivors. A 28-item online survey was designed for cancer patients and survivors diagnosed between the ages of 18 and 39 years. 590 patients registered and 447 (76%) completed the survey. This online survey was feasible and can serve as an effective method to survey the AYA cancer population.
