The Cancer Coach innovates how people undergo cancer treatment and ensures the best possible experience for patients and their families. The Cancer Coach is the Patient Advocate and is a central point of contact for patients and their families throughout the entire complex outpatient cancer treatment process. The Cancer Coach makes patient and family care more proactive and individualized so that challenges can be identified early, treatment adherence can be increased, and treatment can be improved in the short, medium, and long term. At the same time, the new role significantly relieves the medical staff since administrative activities and emotional care, which do not require core medical competence, are taken over by the Cancer Coach.
