Healing the mind/body split: bringing the patient back into oncology

The effect on oncology of the doctrine of Cartesian dualism is examined. It is argued that (1) this doctrine continues to exert a baneful (though unacknowledged) influence on the practice of oncology, (2) Descartes's doctrine of a mind/body split is mistaken, and (3) mind and body (brain) are inextricably interwoven. A biopsychosocial model of disease is advocated. The role of psychooncology in healing the mind/body split by focusing research attention on the patient is outlined.
