International Incidence of Childhood Cancer (IICC) is a collaborative project of the International Agency for Research on Cancer (IARC) and the International Association of Cancer Registries (IACR). This project was co-sponsored by the Union for International Cancer Control (UICC).

The objective is to disseminate the available data on the incidence of cancer in children around the world. This will be achieved through the publication of a monograph, the third volume in the IICC series (IICC-3). Both print and electronic versions are envisaged, with the first results to appear in 2017.

Data from 440 registries in five continents have been collected, validated, analysed, and evaluated. More than 300 registries met the inclusion criteria and provided high-quality comparable datasets and they were selected for publication in IICC-3 after rigorous peer review by the IICC-3 Editors.

Standardized incidence rates were released on the occasion of International Childhood Cancer Day 2017 (15 February 2017).
