Background: Identifying and addressing caregivers' unmet needs have been suggested as a way of reducing their distress and improving their quality of life. However, the needs of family cancer caregivers are complex in the period of long‐term survivorship in particular because they may diverge as the patients' survivorship trajectory does, and that is what this study investigated. Methods: Family cancer caregivers completed prospective, longitudinal surveys 2, 5, and 8 years after diagnosis (n = 633).
