Breast cancer is the most common cancer in women. It is the main cause of cancer deaths among women. The incidence of non-palpable tumors is estimated at 60%. Their better prognosis and their small size encourage the investigators for finding methods simpler and more efficient to treat them by breast-conserving surgery with acceptable cosmetic results. The pre-operative detection of the tumor lesion is currently carried out by two methods: the radioactive seed localization and guidewire technique. Each has its disadvantages: the guidewire is uncomfortable for the patients (pain, hematomes..), whereas the radiocolloid requires a specialized and complex organization around this radioactive product. Recently, a novel method of using indocyanine green (ICG) fluorescence has been described in breast cancer and seems promising. In this study, investigators evaluate the feasibility and performance of indocyanine green fluorescence in non-palpable tumor detection in comparison with radioactive seed localization (ROLL) Secondary objectives are evaluate the feasibility of the location by the radiologist, feasibility of detection by the surgeon, study of the product and the probe.
