What causes swollen lymph nodes in breast cancer?
Swollen lymph nodes can be an early sign that breast cancer has spread. Lymph nodes are small, bean-shaped structures that help filter out harmful substances as part of your immune system.
When breast cancer spreads, it often travels first to the lymph nodes, particularly those in the armpit or near the collarbone. In some cases, swollen lymph nodes may be noticeable before a lump in the breast is detected.
If you have HER2-positive breast cancer, which tends to grow and spread quickly, lymph node swelling may develop early in the disease process.
While swollen lymph nodes can also be caused by infections or other conditions, it's essential to have any unexplained swelling evaluated by a healthcare provider. They can determine the cause and recommend appropriate next steps for diagnosis and treatment.
