RecruitingClinical trialSocial Health, Activity Behaviors, and Quality of Life Among Young Adult Cancer SurvivorsThis study assesses how personal relationships (such as friendships, family relationships, or romantic partners) influence the physical activity (exercise) and well-being of young adult cancer survivors. Researchers also hope to learn how social relationships change after a cancer diagnosis, and how these changes might impact important health behaviors. The information provided may help researchers learn more about better ways to support young cancer patients in the future through interventions that help maintain good social relationships and health levels of physical activity.
