Breast Cancer

To tell if cancer has spread throughout the body (called metastasis), your doctor will likely look at your lymph nodes. Through a sentinel node biopsy (or a sentinel lymphadenectomy), your doctor can identify if cancer is present or not in the sentinel lymph node. This is the first lymph node or group of nodes that will drain cancer. If the test shows that it is node-negative (not indicating any cancer cells), it will be doubtful that other axillary lymph nodes have cancer cells. If the test is node-positive, then you may need to undergo an axillary node dissection.

If cancer has spread to your lymph nodes, an axillary node dissection may be needed. This is a surgery used to remove most of the lymph nodes under the armpit (or axilla). These lymph nodes are organized into three levels (levels I, II, and III), and axillary node dissection removes affected lymph nodes in levels I and II.

Lymphedema is a chronic condition caused by damage or blockage in the lymphatic system, leading to fluid buildup and persistent swelling—most often in the arms or legs. It commonly develops after cancer treatments like surgery or radiation, particularly when lymph nodes are removed or compromised, but it can also result from infections, trauma, or inherited lymphatic disorders. While lymphedema isn’t always preventable, risk can be reduced through proper skin care, avoiding injury or overuse of the affected limb, and maintaining a healthy weight.

Early detection is key—which is why Southcoast Health Breast Care utilizes InBody technology, a non-invasive tool that accurately measures body composition and fluid levels. This allows us to monitor subtle changes over time and identify early signs of lymphedema before visible swelling occurs, enabling proactive care and more effective management through customized treatment plans.
