La biopsia minima dei noduli mammari in fase preclinica

In conjuction with ultrasonography, mammography is the most common instrumental method used in the screening program of subclinical breast lesions. The Authors present their method of preoperative localization and minimal biopsy of subclinical breast lesions. According to our experience, the most efficient technique is founded on marking the suspected area, guided by mammography, with vegetal coal, that remain 'in situ' about 2 weeks. We have performed this procedure in 40 cases. A diagnosis positive for carcinoma was made in 9 cases. Hospitalization of the patients is not necessary: in fact marked lesion is excised under local anaesthesia and the whole operation takes about 30 minutes. Complications have been negligible. The aesthetic result is agreeable and the patients acceptance of a minimal biopsy is good.
