Closing the GAPS: Guideline Adherence, Prevention and Surveillance in Hereditary Cancer

The goal of this clinical trial is to see if a software platform can improve cancer screening in young adults with genetic risk for cancer. The trial will also help improve the software platform (Nest). The main questions it aims to answer are: * Do Nest users know more about their cancer risks and recommended care than non-users? * Do Nest users have less psychological distress than non-users? * Do Nest users share cancer risks with family and other doctors more than non-users? * Are Nest users more likely than non-users to have up-to-date care plans? Researchers will compare Nest users to non-users to see if the Nest users are more likely to do recommended cancer screening. Participants will: * Have a genetic counseling or follow up visit * Take a post-visit survey * Intervention arm only: use the Nest Patient Navigator * Complete screening and follow-up care recommended by doctors
