While the number of new cancer cases in children and adolescents (aged 0-19 years) is relatively low at around 416,500 globally in 2017, treatment-related ill-health and disability and fatal cancer are estimated to cause around 11.5 million years of healthy life lost globally every year, according to the first Global Burden of Disease Study (GBD) to assess childhood and adolescent cancer burden in 195 countries in 2017, published in The Lancet Oncology journal.
