Informing cancer patient in relation to his type of personality: the dependent (oral) patient.

When a doctor has to break bad news to the cancer patient, he knows that the news will put a strain on his relationship with the patient. Bad news is any information that changes a person's view of the future in a negative way. The questions: "Do you tell the diagnosis or not? How much information do you reveal? Who do you inform about the diagnosis and/or what do you tell" are very frequent during scientific discussions. Must the patients know or do they also have the right not to know? Is it possible to determine who should be told what, when and how? The aim of this paper was to describe the dependent character or type of personality, so that a therapist can make a diagnosis in order to determine the informative approach.
