Sentinel Node Biopsy


A sentinel node biopsy is a minimally invasive surgical procedure that determines whether cancer has spread beyond the primary tumor site. The sentinel node is the first lymph node that drains fluid from the tumor, and therefore it is the most likely place for cancer cells to spread. 

A small incision is made in the skin during a sentinel node biopsy, and a radioactive tracer is injected near the tumor. The tracer travels through the lymphatic system and collects in the sentinel node. A surgeon then uses a special camera to locate the sentinel node and removes it for testing.

If the sentinel node tests positive for cancer, the cancer cells have likely spread to other lymph nodes. In this case, additional treatment (such as chemotherapy or radiation therapy) may be necessary. If the sentinel node tests negative for cancer, the cancer is likely confined to the primary tumor site, and further treatment may not be necessary. 

Sentinel node biopsy is a relatively new procedure and is not yet widely available. However, it offers a less invasive alternative to traditional lymph node dissection, which involves removing all the lymph nodes in the affected area.

Everything You Need To Know Sentinel Node Biopsy

What to expect Before, During and after the Sentinel Node Biopsy Procedure?

Before the procedure:

Your doctor will give you a local anesthetic to numb the area around the biopsy site. You can take some sedatives to help you relax.

During the procedure:

A small incision will be made in your skin near the tumor. A special dye will be injected into the sentinel lymph node. This dye helps the surgeon locate the node. 

Once the node is located, a small tissue sample will be removed and sent for testing. The entire procedure usually takes less than 30 minutes.

After the procedure:

Once the Procedure is Done, you will be monitored for any side effects from the Anesthesia. Once it wears off, you can go home. You may have some Bruising and Swelling at the Biopsy Site. 

You Can take over-the-counter pain medication to Help with any Discomfort. Your doctor will give you specific instructions for faster recovery. You will have a follow-up visit with Your Doctor 1 to 2 weeks after the procedure. 

If you have been diagnosed with cancer and your doctor recommends a sentinel node biopsy, it is important to ask questions and understand all of your options. You may also want to get a second opinion from another doctor before making any treatment decisions.

What are the possible Risks and Complications Involved

Sentinel node biopsy is a minimally invasive procedure with a low risk of complications. The most common complication is an infection that can be treated with antibiotics. In rare cases, the sentinel node may not be completely removed and another biopsy may be needed. 

There is also a small risk of damage to the nearby lymph nodes, which can cause lymphedema, where fluid builds up in the tissues and causes swelling. In most cases, lymphedema is treated with compression garments and physical therapy. 

Overall, sentinel node biopsy is a safe and effective way to determine whether cancer has spread to the lymph nodes.

Benefits of Sentinel Node Biopsy

A sentinel node biopsy can have many benefits for patients. The procedure can help determine whether cancer has spread beyond the primary tumor, and how far. This information can be used to make treatment decisions and guide prognosis. In some cases, a sentinel node biopsy may also help avoid more invasive and costly procedures, such as a lymph node dissection. 

In addition, sentinel node biopsies are often less invasive than other types of cancer biopsies, with a shorter recovery time.

 And because they allow doctors to remove only the lymph nodes that are most likely to contain cancerous cells, they may help preserve lymphatic function and reduce the risk of lymphedema Risks of Sentinel Node Biopsy.

Our Patients

I got operated in Nov 2021. The word cancer can be so daunting and brings loads of stress in a patient's life. But i was fortunate that I met the right surgeon - Dr Jay Anam, post meeting him was relaxed and knew I am in safe hands. He explained the surgery in minute detail and patiently answered all my queries. Post surgery outcome was also discussed and nothing was left to guessing. He was on time for the surgery and i have to admit that the cuts and scars are minimal and it was a very clean n neatly done job. Post surgery he was always available on phone for any issue I faced. Post surgery follow up visit was also handled professionally.
