This paper reports the patient care experience during the course of the radiotherapy. Plights are multiple. Patients are confronted with a complex and unknown distressing space, an irrelavant information, a banalization of side effects, an isolation with a frequent inadequate support of their family or the caregivers team, with the fear of a definitive abandonment at the end of the treatment without comforting follow-up. It is imperative to state a real policy in order to improve the patient support. Sensibilization and training of the caregivers, in spite of a frequent overbooking technical work, is required in a pluridisciplinary approach to provide a relevant reception with the collaboration of psychologists, social workers and self care groups and associations. The personal implication of the physicians and technologists is also essential. The simple smile is the intangible proof of the reliable emotional support.
