The DENACAPST programme represents an important initiative to provide near nation-wide roll-out of an important cancer surveillance program for childhood cancer survivors. The program is based on internationally recognized standards in cancer surveillance, which were developed by the International Guideline Harmonization Group (IGHG) with support of all relevant stakeholders in cancer survivorship research and clinical work in Europe, Canada and the United States and recognized French recommendations about breast screening for women at high risk of cancer.
