Psycho-oncology is an interdisciplinary field of medicine that deals with the psychological aspects of cancer. Psycho-oncology is a sub-discipline of clinical oncology, psychiatry, clinical psychology and health psychology. It was formally established in 1975. In Poland, the Polish Psycho-Oncology Association deals with the issues of psycho-oncology since 1992. Despite the dynamic development of psycho-oncology, in Poland psychological help for people with cancer covered under the health insurance is not sufficient. The main tasks facing the Polish psycho-oncology is: to define psycho-oncologist profession and to make it administratively independent profession, to identify psycho-oncological benefits under the health insurance and to determine standards of psycho-oncological care in the National Program of Cancer Prevention.
