Abstract
In breast cancer, the status of the axillary lymph node decides the prognosis of the disease. Axillary lymph node dissection (ALND) was the traditional method to address the lymph node. Final histopathological examination is the confirmatory method to detect metastasis in axillary lymph node. As the tumor stage advances, the rate of metastasis in axillary lymph nodes increases, simultaneously. The positivity rate of axillary lymph nodes in early breast cancer is low as compared to locally advanced breast cancer. The role of Sentinel Lymph Node Biopsy (SLNB) has been emerged, established in early breast cancer and it is universally accepted by most of the medical centers, worldwide. SLNB is indicated in early breast cancer when there are clinically negative nodes by palpation and ultrasound examination. It is the procedure to stage the axilla and it has minimum morbidity as compared to ALND. ALND has been replaced by SLNB at many centers, worldwide. We have reviewed the potential SLNB research studies and prepared a brief review article.
