[Clinical effects of new technologies in medical imagery: the example of breast screening].

In the frame of cancer screening, we present a new psychological concept elaborated from our clinical practice of women affected by a breast cancer. The experience of these women is different depending on whether the cancer is discovered in an asymptomatic context or not. We introduce the concept of "anticipatrice medicine" in order to define the implication of diagnosis precocity on the therapeutic strategy, because of a modification of some main parameters which make up the ordinary personal concept.
