What should you know about lumpectomy SLNB?

A lumpectomy, also called breast-conserving surgery, removes the abnormal area with a rim of surrounding tissue while leaving much of the breast in place. Sentinel lymph node biopsy, often shortened to SLNB, identifies and removes the first lymph nodes that drain the breast. A laboratory examines the removed tissue and nodes. The results help the oncology team decide whether further treatment is needed; they do not come from the appearance of the lump alone.

The operation may leave a breast incision and a small incision near the armpit. Tenderness, bruising, swelling or altered sensation can occur while the area heals. Radiotherapy is often discussed after breast-conserving surgery, depending on the pathology and the overall treatment plan.

Before surgery, ask which medicines to pause, when to stop eating and drinking, and whether someone should take you home. Wear loose clothing and follow the wound-care instructions provided after the operation. Gentle arm movement may be recommended, while heavy lifting is limited until your team says it is appropriate. Keep the follow-up appointment so the pathology results, wound and next treatment decisions can be reviewed. Breast Cancer and Paget Disease of the Breast are examples of conditions in which the surgical plan may be considered.

Contact your surgical team promptly for fever, increasing redness or warmth, worsening swelling, pus, bleeding that does not settle with pressure, or pain that is becoming harder to control. Seek urgent help for sudden breathing difficulty, chest pain, fainting, or rapidly worsening swelling. A new concern near the wound or armpit should also be reported rather than watched in silence.

Ask: Which area and how many sentinel nodes will be removed? How will the tracer or dye be used? When should I expect the pathology report? What arm movements and lifting limits apply? Will Radiotherapy be part of my plan, and what other options should we compare?
