The American Cancer Society defines a
caregiver as a family member, friend, loved one or other support person who lends physical, emotional or other support to someone at any time during the cancer journey.2 Importantly, they are part of a triadic model of involvement together with the patient and healthcare professional and take on
multiple roles, from involvement in treatment decision - making in cancer, to acting as conduits of information between the patient and the specialist and vice versa and supporting the patient's decisions.3
