In this section, we report the number of childhood and adolescent cancer cases, relative frequencies, and crude (not standardized for age) incidence rates for the main diagnostic cancer groups according to the third version of the International Classification of Childhood Cancer (ICCC31), and for Langerhans cell histiocytosis and for all cancers combined. We report incidence for children (0-14 years old) and adolescents (15-19 years old), separately and combined (0-19 years old). We focus on the calendar period 1993-2022. Differences between males and females are shown using male to female ratios and sex-specific incidence rates. We suppress data in tables by setting cells to NA* (not available), if these reveal information on specific patients. For example, if only one patient has a certain diagnosis, we don’t show information related to their age and sex. If all cases of a certain diagnosis are of same sex, we don’t show the sex ratio. Incidence is calculated as the number of new cases per 100,000 persons per year. We follow the same methodology as that used for the Swiss Cancer Report 2021 – Methods Report (available only in German). A more technical description of the methods is provided in chapter 2 of Statistical methods for Cancer Reporting in Switzerland.
