[A manic episode as a result of information about breast cancer diagnosis in a patient suffering from bipolar affective disorder].

The paper describes a patient who suffered from bipolar affective disorder for 22 years and the following manic episode appeared after getting information about a diagnosis of breast cancer. During mania the patient presented delusions of being healthy which caused a marked delay in introducing the necessary treatment of the tumour. Besides, we discuss different authors' views about the possibility of evoking manic episodes by psychological factors. Same authors agree, that such an event may happen but others do not. This matter requires further studies, but any doctor who takes care of a patient with bipolar affective illness should always remember about the possibility of being evoked manic episode by harmful stress events.
