According to research, almost every second oncology patient experiences intense distress during their oncology treatment. The development of new medical treatment options in cancer care allows longer survival for cancer patients. Because of this, quality of life becomes an increasingly important factor during treatments. Psycho-oncological interventions include all psychosocial interventions that are designed to positively influence the patient's psychosocial adaptation and adjustment to diagnosis, treatment, and survivorship. Interventions also promote rehabilitation progress and help the emotional integration of disease-related crisis and trauma. Psycho-oncological therapies are supposed to manage cancer-related distress and other psychosocial problems by specific types of treatments or interventions. It is crucial for the medical system to deal with the psychosocial aspects of cancer care in order to identify and deal with patients' needs for better compliance and adherence to treatment. The key of personalized holistic rehabilitation is multidisciplinary teamwork during the whole healing process: sharing the emotional experience also helps to prevent healthcare workers' burnout.
