ICG Distribution Using NIF Imaging After IV Injection of ICG in Benign and Malignant Breast Cancer Tissue.

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine if NIF fluoresent imaging is an effctive approch to detect the margine of the breast tumoral tissue.

Detailed Description
-----------------
Primary objective: Definition of the histological distribution (intravascular, extra vascular, in specific cells) of ICG (pre-operatively intra-venously injected) at the level of tumoral and healthy tissues of breast cancer patients (and the potential of axillary lymph nodes found fluorescent). Secondary objectives: Evaluation of the ability of the fluorescence imaging to determine the tumor volume and, more specifically, the boundaries of tumor tissues which will be analyzed by the pathologist. Analysis of the correlation between fluorescence and margins as defined operatively as tumor (microscopically by the pathologist).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Study of the evantual difference of indocyanine in mammalian tissue in patients mastocmemezied for breast canrcinoma. | Detecting of the fluorescence in between benign and malignant tissue by near infra-red imaging with a camera dictated to identify the margin of the tumor, and Histological detection of indocyanine green distribution in tumor bearing breasts and in axillary pieces of dissection and the detection of tumor cells in lymphe nodes. | 10 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Microscopical detection of indocyanine green in breast tissue. | Detecting the fluorescence in between benign and malignant tissue by a microscope with a filter for near ifra-red at a good wave length of ICG. | 10 months. |
