P617: Impact of population genomic screening on patient behavior and care: Changes in preventive screening behaviors among HBOC positive individuals

Population genomic screening has emerged as a promising approach to identify individuals with hereditary breast and ovarian cancer (HBOC). However, there are often concerns that patients identified as high risk will not get appropriate downstream management. This study aims to investigate the impact of population genomic screening on patient behavior and management, focusing on uptake of updated breast cancer preventive screening recommendations among HBOC positive individuals. Additionally, we aimed to explore factors contributing to patients’ uptake of updated guidelines.
