If you don't need additional surgery, you may be able to go home the same day.
You may be moved to a recovery room where your health care team watches for complications from the procedure. Or sentinel node biopsy can be done before or after surgery to remove the cancer. Often the sentinel node biopsy is done at the same time as surgery to remove the cancer. The sentinel nodes are sent to a lab where they are examined under a microscope for signs of cancer. Typically, there are a few sentinel nodes, and all are removed. The surgeon then removes the sentinel nodes. If the blue dye is used, it stains the sentinel nodes bright blue so the surgeon can see them. The lymph nodes with the most radioactive solution are the sentinel nodes. The surgeon uses a small hand-held instrument called a gamma detector to find the spots where the radioactivity has built up. When radioactive solution is used before the procedure, radioactivity builds up in the sentinel nodes. The surgeon begins by making a small incision in the area over the lymph nodes. You're likely to be given medicine to put you in a sleep-like state during the procedure. Some surgeons use both techniques in the same procedure. Whether you receive the radioactive solution or the blue dye or both to locate the sentinel nodes is usually determined by your surgeon's preference. The blue dye is typically injected just before the sentinel node biopsy. You also might notice that your urine is blue for a brief time. This color usually goes away, but it can be permanent.
Sentinel lymph node skin#
You might notice a change in your skin color at the injection site. The dye travels to the sentinel nodes, staining them bright blue. In this option, a harmless blue dye is injected into the area near the cancer. This injection is usually done several hours or the day before the surgical procedure to remove the sentinel nodes.īlue dye. This solution is taken up by the lymphatic system and travels to the sentinel nodes. In this option, a weak radioactive solution is injected near the cancer. The first step in a sentinel node biopsy is to find the sentinel nodes. Ask your health care team for specific instructions. This is to avoid complications from the medicine used to put you in a sleep-like state during surgery. You might need to stop eating and drinking for a period of time before the procedure. Typically, those remaining lymph nodes can take over for the lymph nodes that are removed. Dozens of other lymph nodes remain in the area where the sentinel node biopsy is done.
Lymphedema is more likely to happen if many lymph nodes are removed from one area.īecause only a few lymph nodes are removed in sentinel node biopsy, the risk of lymphedema is small. Lymphedema is an unlikely complication of sentinel node biopsy.
Fluid buildup and swelling in lymph vessels, which is called lymphedema.Allergic reaction to the dye used for the procedure.But as with any surgery, it carries a risk of complications, including: Sentinel node biopsy is generally a safe procedure.
