# Prevalence of childhood cancer in Canada: an analysis using 5-year, 18-year and 25-year limited-duration prevalence from the CYP-C data tool

## TL;DR

This study reports on the prevalence of childhood cancer in Canada using data from the CYP-C tool, highlighting trends and regional differences.

## Contribution

The study provides updated prevalence estimates using 5-year, 18-year, and 25-year limited-duration prevalence data from the CYP-C data tool.

## Key findings

- By 2021, 4325 children under 20 with a cancer diagnosis in the past 5 years were alive.
- Age-standardized 5-year prevalence increased by 12% over 15 years.
- Leukemia was the most prevalent childhood cancer in Canada.

## Abstract

Survivors of childhood cancers can face life-long health risks. In this study we describe the prevalence of childhood cancer in Canada by type, geographic region, year, age group and sex, using publicly available data in the Cancer in Young People in Canada (CYP-C) data tool. By 2021, 4325 people aged less than 20 years who had received a cancer diagnosis within the previous 5 years were still alive. The age-standardized 5-year prevalence increased by 12% over the past 15 years. Leukemia was the most prevalent childhood cancer. The CYP-C data tool provides comprehensive and timely public health surveillance statistics to understand the burden of childhood cancer.
