Cancers in children (0–14 years of age) differ from those occurring in adults in both their site of origin and their behaviour.
Embryonal and hematologic (blood) cancers are more prevalent among children, whereas epithelial tumors are more prevalent among adults. The most frequently diagnosed cancers in children between the ages of 0-14 were leukemia (33%); central nervous system cancers (18%); lymphoma (14%); neuroblastoma as well as other peripheral nervous cell tumours (7%), and soft tissue (6%). Childhood cancers altogether have a one-year survival of 93% and a five year survival of 84%.
