[The psychological taking charge of the oncological patient: a 3 years study on the activities of psychologists of the Piedmont and Aosta Valley Oncology Network.].

Introduction: Tumor pathology is a bio-psycho-social event that has consequences for a person's life from all points of view, physical, psychological, relational and social. The mental discomfort that chronic pain and neoplastic pathology brings with it is present in 25-40% of cases, but the request for help to a psychologist, where not provided for by a specific diagnostic therapeutic assistance path, is in the case of medical pathologies less than 3%. The Piedmont and Valle d'Aosta Oncology Network has the role of coordinating the network of services that deal with the care of the cancer patient, including those relating to psycho-oncology.
