Recorded childhood cancers rise by 13% worldwide, study finds

Survival rates improve across the globe, as increase in cases over 20 years attributed largely to better detection and recording

Childhood cancers have risen across the globe by 13% over 20 years, according to data from the World Health Organization's cancer section.

Cancer in children is comparatively rare; when it does occur it is more likely to have been triggered by something in the child's genetic makeup than by anything to do with lifestyle or the environment.
