title: Increased uptake of social security benefits among long-term survivors of cancer in childhood, adolescence and young adulthood: a Norwegian population-based cohort study.
abstract: BACKGROUND
  As the number of cancer survivors increases, their health and welfare have come into focus. Thus, long-term medical consequences of cancer at a young age (<25 years), obtained from social security benefit records, were studied.
  
  
  METHODS
  Standardised incidence ratios (SIRs) of long-term medical consequences for 5-year cancer survivors, born during 1965-1985, were explored by linking population-based registries in Norway.
  
  
  RESULTS
  Among the 5-year cancer survivors (4031 individuals), 29.7% received social security benefits. The survivors had an overall 4.4 times (95% confidence interval (95% CI): 4.1-4.6) higher risk of social security benefit uptake than the cancer-free population. Survivors of malignancies of bone and connective tissues (SIR: 10.8; 95% CI: 9.1-12.9), CNS tumours (SIR: 7.7; 95% CI: 6.9-8.6) and malignancies of the haematopoietic system (SIR: 6.1; 95% CI: 5.3-7.0) had the highest risks of social security benefits uptake. The most notified causes of social security benefit uptake were diseases of the nervous system, and injury and poisoning.
  
  
  CONCLUSIONS
  The uptake of social security benefits among 5-year cancer survivors increased substantially and it may represent a solid outcome measure for the burden of the most severe late effects, especially in countries with comparable social welfare systems.
