Sentinel Lymph Node Biopsy Explained By Breast Surgeon

Sentinel Lymph Node Biopsy (SLNB) Concept
📌 The sentinel lymph node biopsy (SLNB) identifies the initial lymph nodes draining breast fluid, acting as the body's "guard" node.
🎯 If a patient is destined to have positive lymph nodes, the sentinel nodes are the most likely to be involved first.
🔬 Techniques exist for performing SLNB concurrently with the primary cancer treatment.

Pre-Surgery Lymph Node Biopsy Importance
🔎 A lymph node biopsy may be performed upfront if an enlarged node is detected via physical exam, MRI, or ultrasound, before any surgery.
📊 This upfront biopsy is crucial for determining the patient's stage accurately.
💊 Knowing the stage beforehand may influence the decision to administer neoadjuvant chemotherapy prior to the primary surgery.

Evolving Standards in Lymph Node Management
⚠️ The standard practice for removing lymph nodes, known as axillary lymph node dissection (ALND), is currently undergoing changes.
🗣️ Patients newly diagnosed with breast cancer need specific information regarding personalized breast cancer treatment and the use of Genomic Tests.

Key Points & Insights
➡️ The Sentinel Lymph Node is the first drainage point from the breast, making it a key indicator if cancer has spread to the lymph system.
➡️ Performing a core biopsy on an enlarged lymph node before surgery is vital for staging and determining if neoadjuvant chemotherapy is necessary.
➡️ Personalized breast cancer treatment, guided by Genomic Tests, is an essential topic for newly diagnosed patients to discuss with their doctors.
