The number of teenagers and young adults dying from cancer in the UK has halved since the 1970s, according to a report from Cancer Research UK.
Deaths fell from about 580 per year to 300 in this age group while the largest drop was in those with leukaemia.
More specialised treatments are likely to be behind the trend, the report said. However, a teenage cancer expert said more young people should be enrolled on clinical trials.
Cancer remains the main cause of death from any disease in teenagers and young adults.
