National Breast and Thyroid Screening After a Treatment Received Against a Cancer During Childhood

Study Overview
=================
Brief Summary
-----------------
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. With this programme, French centers organized themselves to provide to childhood cancer survivors adequate medical attention, which includes close medical surveillance for breast/thyroid cancer where appropriate, based on adequate risk stratification. The aim of the study is to analyze if the recommendations about breast and thyroid cancer screening are followed in this population and secondly to provide more informations about these second cancers and about the screening.

Detailed Description
-----------------
Every center which has patient at risk can participate. Main inclusion criteria : French childhood cancer survivor (5 years or more of delay with the treatment) - becoming adult - with a past history of radiotherapy at the age of 20 years or before, with a significant dose irradiation on the thyroid or the breast The inclusion of patients are validated by one team Thyroid screening programme is based on US each 2 years Breast screening programme is based mainly on MRI each year
