Malignant disease is undoubtedly an extraordinary situation demanding trust in the relation between the patient and the doctor. From the legal aspect, any treatment and especially the surgical one is an attack on the integrity of the patient and is not allowed without the agreement of the patients. The relationship between the patient and the doctor begins with at the first consultation and should not end after discharge from hospital. Periodical examinations, repeated admissions and treatment of the malignant disease sequelae, make the relationship between the patient and the doctor a lifelong one.
