Breast cancer in female survivors of childhood, adolescent or young adult cancer after radiotherapy involving the chest for their primary malignancy

To summarise the existing evidence regarding the effects of radiotherapy involving the chest for childhood, adolescent and young adult cancer on breast cancer risk in female cancer survivors. Firstly we will describe the overall breast cancer risk, as reported in all eligible studies. Secondly, we will summarise the breast cancer risk associated with (a) characteristics of treatment for a previous cancer, (b) survivor characteristics, and (c) modifying traditional predictors for breast cancer.

This is a protocol.
