As radiotherapy declined so did second cancers in childhood cancer survivors

Childhood cancer survivors are living longer. Now research shows they are also less likely to develop second cancers while still young. The decline followed a sharp drop in the use of radiation therapy for treatment of childhood cancers. Between the 1970s and the 1990s, the percentage of paediatric cancer patients treated with radiation fell from 77 to 33 percent. The average radiation dose also dropped. Their chance of having second cancers within 15 years of the first fell as well. The research is published online in the Journal of the American Medical Association.
