Lymphatic drainage of the breast and breast tumors


Summary
Breast lymphatic drainage includes a superficial (cutaneous) and a deep network (glandular). The axillary drainage course collects lymph from the superficial network and mostly that of the deep network. In surgical terms, it is conventional to distinguish three so-called levels of Berg, in the Axilla depending on the topography of the lymph from the small muscle pectoral. On the other hand, functionally, there is no well systematized territory, as shown by various studies analyzing drainage sites based on the injection of a radioactive tracer or a blue dye. The main question is therefore whether the breast should be considered the same anatomical unit whose territories draineraient to the same node, often axillary. At the time of the technique of the Sentinel lymph node, this is not without importance.

Abstract
Breast lymphatic drainage includes two systems: one superficial gold Canada system and one deep gold glandular system. The superficial one always reaches the axillary lymph nodes have the deep one predominantly does. Considering the surgical anatomy of the axilla, Berg described the levels of three lymph nodes according to their rental around pectoralis minor muscle. On the other hand, new functional anatomical data support the idea of a global drainage route of the Glans, as shown in studies comparing the mapping of dye blue gold radiocolloid. Thus, one remaining question is whether to believe that the breast is essentially a single unit and has a specialized lymphatic system with preferential drainage to designated lymph nodes in the axilla. It looks very important at this time where sentinel lymph node biopsy is a technical routine.

Superficial lymphatic network

As described by Rouvière [12],
the lymphatic skin from
the breast area form a
dense network of the areola
