Survival from breast cancer is poorer in East London than in England as a whole. Also, there are inequalities in breast cancer survival within East London. There is a need to address such inequalities, and generally promote primary prevention and earlier diagnosis of breast cancer. This research will identify gaps in delivery locally, search the literature for interventions that could improve prevention and early diagnosis and engage with stakeholders (including patients, communities, clinicians and decision makers) to understand barriers and changes needed to improve care for all. Our findings will underpin a proposal for further research to evaluate the process and outcomes of transformation to services aiming to improve breast cancer outcomes.
