Incidence trends from the Spanish Network of Cancer Registries (REDECAN)\". A population-based study within REDECAN using data from 15 cancer registries included every new cancer diagnosed in people aged 20 to 49 between 1993 and 2018, 153,599 cases, 58% of them in women. Truncated age-standardised incidence rates were calculated with the European standard population and trends assessed with Joinpoint regression to estimate the annual percent change.
