Cancer is a devastating disease in children. Although pediatric cancer is relatively rare, it is the leading cause of death by disease past infancy among children in the United States. More specifically, acute lymphoblastic leukemia (ALL) is the most common cancer and cause of leukemia in children. The treatment for childhood cancer has improved substantially over the past few decades. Nevertheless, childhood cancer survivors have a significantly higher risk of developing chronic health conditions, compared to other healthier children. Specifically, they are more likely to suffer from heart disease, diabetes, and hypertension later on in life.
