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.
