Little more than one decade ago the vast majority of the patients that had a palpable nodule or a suspicious image detected in an test  were submitted to a diagnostic surgery and if the analysis of the cells turned out to be harmful, were put through to a greater surgery.  With the arrival of new technologies and more trained professionals a step up happened to earlier surgery.  The execution of biopsies with fine needle or gross has already been consolidated in the environment of the international mammary interventionism.  Nevertheless, other methods exist that have been developing in these last years: first was the mamotomo that derived in which today biopsy attended is called empty.  This technique is carried out in a high stretcher where the patient reclines in prone position, while the professional locates with maximum precision the place to make an incision with low local aesthesia in great part of the wound in study.  The technological evolution and the professional improvement seeks that women will have their diagnosis as soon as possible with the smaller possible consequences.
