It should be done only by a surgeon who has experience with this technique. It might be used for women with locally advanced breast cancer in certain instances, such as after neoadjuvant treatment.Īlthough SLNB has become a common procedure, it requires a great deal of skill. SLNB is often considered for women with early-stage breast cancer and is typically not used for women with inflammatory breast cancer. If there is no cancer in the sentinel node(s), it's very unlikely that the cancer has spread to other lymph nodes, so no further lymph node surgery will be needed. Women who have lymph nodes with a very small amount of cancer (no more than 2.0mm) and are having a mastectomy.Women with tumors 5 cm (2 inches) or smaller who have no more than 2 positive sentinel lymph nodes, are having breast-conserving surgery followed by radiation, and did not get any chemotherapy before surgery.This is based on certain factors, such as the size of the breast tumor, what type of surgery is used to remove the tumor, and what treatment is planned after surgery, among other things.īased on the studies that have looked at this, skipping the ALND may be an option for: Studies have shown, however, that in some cases it may be safe to leave the rest of the lymph nodes behind. If cancer is found in the sentinel node(s) later, the surgeon may recommend an ALND at a later time to check more nodes for cancer. If no cancer cells are seen in the node(s) at the time of the surgery, or if they are not checked by a pathologist at the time of the surgery, they will be examined more closely over the next several days. Because there is a chance that other lymph nodes in the same area will also have cancer if cancer is found in the sentinel lymph node(s), the surgeon may go ahead with an axillary dissection (ALND) to remove more lymph nodes while you are still on the operating table. Sometimes, this is done during the surgery. The few removed lymph nodes are then checked closely in the lab for cancer cells by a pathologist. The surgeon cuts the skin over the lymph node area and removes the affected node(s). Looking for nodes that have turned blue (or brown, if iron oxide particles are used). Using a special machine to detect either radioactivity or iron oxide particles in the nodes.The first lymph node(s) the substance travels to will be the sentinel node(s).Īfter the substance has been injected, the sentinel node(s) can be found by: Lymph vessels will carry these substances along the same path that the cancer would likely take. A liquid containing coated iron oxide particles.A radioactive substance and/or a blue dye, OR.To do this, a substance is injected into the tumor, the area around it, or the area around the nipple. In a sentinel lymph node biopsy (SLNB), the surgeon finds and removes the first lymph node(s) to which a cancer is likely to spread (called the sentinel nodes). Lymph node surgery is often done as part of the main surgery to remove the breast cancer, but sometimes it might be done as a separate operation. In some cases, an axillary lymph node dissection (ALND), which removes more lymph nodes, might be needed.Most often, a s entinel lymph node biopsy (SLNB) is done, during which only a few lymph nodes are removed.Types of lymph node surgeryĮven if the nearby lymph nodes are not enlarged, they will still need to be checked for cancer. If cancer is found in the lymph node, more nodes will need to be removed (see below). Less often, the enlarged node is removed with surgery. If any of the lymph nodes under the arm or around the collarbone are swollen, they may be checked for cancer with a needle biopsy, either a fine needle aspiration (FNA) or a core needle biopsy. Lymph node removal can be done in different ways, depending on whether any lymph nodes are enlarged, how big the breast tumor is, and other factors. More imaging tests might be done if this is the case. If the lymph nodes have cancer cells, there is a higher chance that cancer cells have also spread to other parts of the body. To help find out if the cancer has spread outside the breast, one or more of the lymph nodes under the arm (axillary lymph nodes) are removed and checked in the lab. If you have been diagnosed with breast cancer, it’s important to find out how far the cancer has spread. Knowing if the cancer has spread to your lymph nodes helps doctors find the best way to treat your cancer. It can also sometimes spread to lymph nodes near the collarbone or near the breastbone (the front center of the chest). If breast cancer spreads, it typically goes first to nearby lymph nodes under the arm.
