| Code | Display | Definition |

| EnlargedNode | When cancer has spread to the axillary lymph nodes, the nodes may feel enlarged, or there may be a noticeable lump. A breast cancer prognosis is better when the cancer is only in the breast, and the lymph nodes are not affected. Most people who have enlarged axillary lymph nodes do not have cancer at all. | When cancer has spread to the axillary lymph nodes, the nodes may feel enlarged, or there may be a noticeable lump.
