Understanding lymph node involvement
What it means if cancer reached a nearby lymph node
The short version
Lymph nodes near the breast, especially under the arm, are often checked for cancer cells during surgery. Finding cancer cells there affects staging and may be discussed as part of your treatment plan.
Breast cancer can sometimes spread first to nearby , especially those under the arm (axillary nodes). Checking these nodes — often during surgery, via a — helps determine stage and informs decisions about treatment.
- Node-negative — no cancer cells found in the nodes examined
- Node-positive — cancer cells found in one or more nodes; the number involved is usually reported
A node-positive result does not mean cancer has spread throughout the body — it specifically describes nearby lymph nodes and is one input, alongside others, into your overall treatment plan.
