[The breast in adolescence. Physiopathological and clinical considerations].

Mammary pathology, during adolescence, is an uncommon event and generally not very serious. During this growth period the different tissue mammary components are influenced by metabolic and hormonal stimulus in a proliferative and differentiative sense. In this growth period an efficient clinical approach is really necessary and it must not be only confined to senologic control, but inserted in the traditional semeiotics of a teenage patient, associated with a practice of self-palpation from the conclusive phases of the mammary development.
