Role of Hormonal Receptor in Predicting Sentinel Lymph Node Metastasis in Early Breast Cancer.

Background: Sentinel lymph node biopsy is one of the minimally invasive techniques that can confirm the presence of metastasis of regional lymph nodes in cancer. Sentinel lymph node biopsy can be done with a lymph mapping technique using blue-dye, radiotracer, or a combination of both. In developing countries, sentinel lymph node biopsy is often done with a single agent, which is the blue dye.
