Lymphatic mapping is the first step in sentinel node biopsy. It is done to find the sentinel node. Lymphatic mapping can be done the same day or the day before the sentinel node biopsy. Intramedical Imaging has the equipment to perform the lymphatic mapping procedure.

What is the procedure like?

During your mapping procedure

During your procedure, you will be in a reclining chair for approximately 20 minutes. While you are in the reclining chair, a doctor or nurse will inject a small amount of radioactive fluid under the skin under the areola of the affected breast. You may feel stinging or burning during the injection.

After the injection, the injection site area will be massaged for 10 minutes. This will help the radioactive fluid move to the sentinel nodes. Then, a technologist will measure the radioactivity in the breast, armpit, and thigh on the affected side to see how much fluid was absorbed. There are 2 ways to do this:

The technologist can use a small hand-held device called a neoprobe gamma detection system.

You may have a full-body imaging scan with a larger machine that you will be lying on.

Both methods work equally well. Your doctor or nurse will tell you what to expect.

After your mapping procedure

If you are having a sentinel node biopsy on the same day as the mapping procedure, you will be taken to the area where the biopsy will be done.

If you are not having the biopsy on the same day as the mapping procedure, you will go home after the mapping procedure.


Sentinel node biopsy

Before your biopsy procedure

A sentinel node biopsy is a surgical procedure. Many people have sentinel node biopsy during breast or melanoma surgery.


During your biopsy procedure

You will be given anesthesia (medicine to make you sleep) before the procedure.

Once you are asleep, the surgeon will inject a small amount of blue dye near the cancer site. This dye will travel through the lymph vessels to the sentinel nodes and stain them blue.

Next, the surgeon will use a Neoprobe gamma detection system to measure the radioactivity of the injected fluid during your lymphatic mapping procedure. Once he locates the area where the sentinel nodes are located, he will make an incision (a surgical cut). He will look for the blue sentinel nodes and remove them.

If the sentinel nodes contain cancer cells, it may be necessary to remove more lymph nodes. This is called an axillary lymph node dissection. Your doctor will discuss this with you in more detail, if necessary.


After your biopsy procedure

You may be able to go home the same day as your biopsy or you may need to stay in the hospital. This depends on how many other surgeries you had. Your doctor or nurse will tell you what to expect.
