Detection of the sentinel lymph node

Abstract

In case of breast cancer spread the lymphatic system is the first organ to be infected. This makes this system a good indicator for cancer presence. The spread extension will be decisive in the choice of treatment to be made. When a breast tumor is detected usually two different techniques are employed: the extraction of the totality of the axilla nodes or the biopsy of the sentinel lymph node. The first case is a highly invasive procedure where 10 to 15 nodes are removed (ALND: Axillary Lymph Node Dissection). (...)
