Experiences across a genetic screening and testing programme pathway: a qualitative study of mammogram patient perspectives.

Background: Population-based genetic screening and testing programmes have substantial potential to improve cancer-related outcomes through early detection and cancer prevention. Yet, genetic testing for cancer risk remains largely underused. This study aimed to describe barriers and facilitators to patient engagement at each stage of a California-based genetic screening programme, from completing the electronic screener to receiving the test and to identify potential improvements that could support precision medicine-based approaches to patient care.
