Child cancer survivors have fivefold risk of new primary malignancy
First national data shows increased risk lingers for decades, researchers report
The risk of developing a second primary cancer is five times higher in people who have survived childhood cancer than in the general population, according to Australian researchers.
Their large population-based study also showed that the risk of a second cancer peaked at two to five years after the initial diagnosis but remained 2.5 times higher for up to 33 years.
