About Sentinel Node Biopsy
Key Highlights
-
Minimally invasive procedure with high diagnostic accuracy.Helps in accurate cancer staging without extensive surgery.Significantly reduces the risk of lymphedema compared to full lymph node removal.Guides personalized treatment decisions (e.g., need for further surgery or chemotherapy).Typically performed as a same-day or short-stay procedure.Leads to faster recovery and less post-operative pain./ul
Who is this surgery for?
- Diagnosed early-stage breast cancer (invasive ductal or lobular carcinoma).
- Diagnosed melanoma with a certain thickness (Breslow depth).
- Some cases of other cancers like penile, vulvar, or head and neck cancers.
- To determine if cancer has metastasized to the lymph nodes when imaging is inconclusive.
- As part of the surgical planning for tumor removal.
How to prepare
- Complete pre-operative medical evaluation, including blood tests and possibly an ECG.
- Discussion of all medications (especially blood thinners) with the surgeon; some may need to be paused.
- Fasting for 6-8 hours before the procedure as per anesthesia guidelines.
- Injection of a small amount of radioactive tracer and/or blue dye near the tumor site on the day of or before surgery to map the lymph nodes.
- Arranging for someone to drive you home after the procedure.
Risks & possible complications
- Allergic reaction to the blue dye (rare).
- Infection, bleeding, or bruising at the injection or incision site.
- Seroma (fluid collection) or hematoma (blood collection).
- Temporary skin discoloration from the blue dye or altered sensation.
- Risk of a false-negative result (cancer is present but not detected in the sentinel node).
- Small risk of lymphedema, though much lower than with full lymph node dissection.
Recovery & hospital stay
- Most patients can go home the same day or after a short observation period.
- Mild pain or discomfort at the incision site is managed with prescribed pain medication.
- Keep the surgical area clean and dry; follow specific instructions on showering and dressing changes.
- Avoid strenuous activity, heavy lifting, and vigorous arm movements (for upper body procedures) for 1-2 weeks.
- Attend all follow-up appointments to discuss the biopsy results and next steps in treatment.
- Watch for signs of infection (increased redness, swelling, fever, or pus) and contact your doctor immediately if they occur.
-
Typical hospital stay: 0-1 days
-
Expected recovery time: 1-2 weeks

Saanvi Chopra, a 48-year-old high school...
Saanvi Chopra, a 48-year-old high school biology teacher and mother of two, discovered a small, painless lump in her left breast during a routine self-exam. She had no family history of breast cancer. A mammogram and subsequent ultrasound revealed a suspicious 1.5 cm mass. A core needle biopsy confirmed it was an early-stage invasive ductal carcinoma. Her surgical oncologist, Dr. Evans, explained that a Sentinel Node Biopsy was the standard next step to see if the cancer had spread to her lymph nodes, which would guide further treatment. Saanvi was terrified of a full axillary dissection and its potential for lifelong lymphedema, so she was relieved by the minimally invasive nature of the sentinel node procedure. The day of surgery, she received an injection of a radioactive tracer and blue dye near the tumor to map the lymphatic drainage. During the lumpectomy, Dr. Evans removed the tumor and the two 'sentinel' nodes that lit up. The procedure itself was straightforward, and Saanvi went home the same day with mild soreness and bruising under her arm. A week later, the pathology report came back: the sentinel nodes were clear of cancer. Her emotional journey was a rollercoaster, initial shock and fear of a 'death sentence' gave way to immense relief and cautious optimism upon hearing the negative node results. She felt empowered to move forward with radiation therapy knowing her prognosis was excellent, and she was profoundly grateful to have avoided more extensive lymph node surgery.
