Patient Centered Clinical Decision Support for Hereditary Cancer Syndromes

The goal of this clinical trial is to address care gaps for participants at high risk of breast and ovarian cancer (HBOC), or Lynch syndrome (LS) because of testing positive for specific genetic variants. A patient-centered clinical decision support (PC-CDS) tool will help identify participants with genetic variations and display recommendations for referrals and testing to the clinician and participant at a primary care visit. The main question the study aims to answer is: \- Does clinical decision support for participants with hereditary cancer syndromes improve the use of evidence-based cancer prevention care. Participants being seen in the PC-CDS group are compared to participants being seen in usual care (UC) to see if they are up to date on guideline-based cancer prevention care and to see if participants in the PC-CDS group report more shared decision making and higher rates of self-management of their genetic cancer risks. Participants will be asked to answer survey questions.
