A small amount of radioactive material is injected around the cancer or under the nipple. It is usually performed in a nuclear medicine or X-ray department. Lymphatic mapping is performed the day before, or a few hours before surgery. These techniques produce a ‘road map’ to help the surgeon find the sentinel node for removal during the operation.

The sentinel node is identified, or ‘mapped’ using a combination of techniques. Sentinel lymph node biopsy is a technique that aims to identify and remove just the sentinel node/s and no others. It is thought that if breast cancer cells were to escape into the lymphatic system, they would travel to the sentinel node/s before moving on to other nodes and the rest of the body. Usually there are between one and three sentinel nodes. The sentinel node/s are the lymph nodes that fluid from the breast ‘drains’ to first. If cancer cells are found in the sentinel node then axillary clearance is sometimes recommended. There are still some situations when axillary clearance is needed. Removing only the sentinel or ‘guardian’ nodes lessens the likelihood of complications and in most cases still provides the necessary information about the cancer. It aims to avoid some of the side effects of axillary clearance by removing fewer glands. Sentinel node biopsy is a technique that has evolved over recent years and it is now the usual way to assess the lymph nodes in women with early breast cancer.

Axillary clearance is a very effective operation to get information about whether or not the cancer has spread to the lymph nodes. This operation is called axillary clearance or axillary dissection.

In the past, the usual operation for breast cancer was to remove most, if not all of the lymph nodes from the armpit on the same side as the breast cancer. Smaller breast cancers are less likely to involve the lymph nodes. The chance of cancer spreading to the lymph nodes is partly determined by the size of the cancer.

Overall, about 70% of women with breast cancer will not have cancer in the lymph glands. Testing the lymph nodes is very important, as it gives you and your doctor information about the breast cancer. Treatment for breast cancer usually involves removing some lymph nodes as well as removing the cancer from the breast. Other lymph nodes that can become involved with breast cancer are located near the collarbone and behind the breastbone. The lymph nodes that filter waste fluid and cells from the breast are mainly located in the armpit (also called the axilla.) These lymph nodes are usually the first ones affected if cancer spreads beyond the breast. Tiny channels (called lymphatics) carry fluid and debris to the lymph nodes which act as filters. Lymph nodes (also called lymph glands) are part of the body’s immune system.
