Introduction  
Of all childhood cancers, bone cancer accounts for about 6%.  It most often strikes teenagers during growth spurts, usually affecting the bones of the arms and legs.  Fortunately, with improved medical technologies and treatments, the cure rate for young bone cancer patients has increased dramatically over the last couple of decades. 

Osteosarcoma and Ewing's sarcoma are the two most common forms of bone cancer.  These are described more specifically in the respective sections.
