Underscoring the role of interprofessional communication, this chapter explains cancer survivorship care planning and the transition to patient care after active cancer treatment ends. This transition and the post-treatment period is often a source of uncertainty that is anxiety-inducing for cancer survivors. This is largely because they see their interprofessional care providers go from being a coordinated and co-located oncology team whose members share goals and information about care to a constellation of different care providers across the health and social care network. Disjointed communication and discontinuous relationships with care providers can be significant sourses of uncertainty. The implementation of a survivorship care plan, including what has been and what needs to be done, is one way to address these communication challenges and bolster patient-centered care.
