Cancer in childhood is no longer a diagnosis yielding no hope as it used to be. For acute lympho-
blastic leukaemia, the cure rate has increased from less than 10% to greater than 80% in only three decades, and the survival rate has increased dramatically also for many other types of cancer in children. This is the result of improved diagnostic procedures, staging, treatment protocols and follow-up procedures. As many more patients survive, more attention now needs to be paid to later sequelae of the disease itself, and perhaps even more from the treatment.
