Axillary dissection
If a sentinel lymph node is found to contain cancer during a mastectomy or lumpectomy procedure, the standard treatment is to also perform an axillary dissection to remove the remaining lymph nodes under the arm. These nodes also will be examined, and if they are found to contain cancer, the chances that the cancer has spread to other parts of the body will be greater. In these situations more aggressive medications or treatment will be recommended.
