Update on the FH01 study

FH01 is a single-arm study of annual mammography in women aged 40–49 with a moderate family history of breast cancer. Originally, it was planned to recruit 10,000 women but this has been revised to 6,000. In this presentation we summarise the considerations that informed the study and its design, the problems encountered and the progress of the study so far. Implications for future studies in specific risk groups are discussed.
