Sentinel Lymph Node Biopsy for Breast Cancer
What is a Sentinel Lymph Node Biopsy?
A Sentinel Lymph Node Biopsy (SLNB) is a minimally invasive procedure used to determine whether breast cancer has spread to the lymph nodes. The sentinel lymph node is the first lymph node (or group of nodes) to which cancer cells are likely to spread from the original tumor.
By analyzing this node, doctors can assess the extent of cancer and plan appropriate treatment—without needing to remove all lymph nodes, which reduces complications and speeds up recovery.
Why is SLNB Important?
- Helps stage breast cancer accurately
- Determines if cancer has spread beyond the breast
- Assists in deciding whether further surgery or radiation is needed
- Helps avoid unnecessary removal of lymph nodes
Who Needs a Sentinel Lymph Node Biopsy?
SLNB is typically recommended for patients with:- Early-stage breast cancer
- Invasive breast carcinoma
- Ductal carcinoma in situ (DCIS) when a mastectomy is planned
- Clinically node-negative breast cancer
How is the Procedure Performed?
- A tracer substance (radioactive material and/or blue dye) is injected near the tumor site
- This tracer travels to the sentinel lymph nodes
- The surgeon uses a gamma probe or visual inspection to locate and remove the sentinel nodes
- The nodes are sent to pathology for cancer analysis
The procedure is often done during lumpectomy or mastectomy surgery under general anesthesia.
Benefits of SLNB
- Accurate cancer staging
- Less invasive than full axillary lymph node dissection
- Lower risk of complications such as lymphedema (arm swelling)
- Faster recovery with fewer long-term side effects
Risks and Possible Side Effects
- Mild pain or bruising at the injection site
- Temporary blue discoloration of skin or urine (due to dye)
- Rare allergic reaction to dye
- Small risk of lymphedema or nerve injury
After the Procedure
- Most patients go home the same day
- Normal activities can often resume in a few days
- Final results from pathology typically take a few days
- Further treatment (like chemotherapy or radiation) is planned based on findings
