Axillary Node Clearance
Axillary clearance removes a group of underarm nodes when more extensive treatment or staging is needed.
The key things to know
- Clearance is not required for every positive node.
- Rehabilitation and early swelling assessment matter.
- The operation is one part of a combined treatment plan.
Why clearance is considered
Axillary lymph-node dissection removes more nodes than a sentinel-node biopsy. It may be recommended for particular patterns of proven nodal disease, persistent disease after preoperative treatment, or circumstances where a more limited approach is not appropriate. Modern treatment allows some people to avoid it. The decision should consider the breast operation, nodal burden, radiotherapy, and systemic therapy together.
What the operation tells the team
The removed tissue is examined to determine how many sampled nodes contain cancer and how much disease is present. This information can influence additional treatment. The number of nodes removed varies between people; a higher count alone does not mean better surgery. Ask why clearance is preferred over sentinel-node surgery, axillary radiotherapy, or observation in your particular situation.
Arm and shoulder effects
Possible effects include numbness of the upper inner arm, fluid collection, tight cords under the skin, pain, and reduced shoulder movement. Lymphoedema may develop months or years later, and risk can increase when surgery and nodal radiotherapy are combined. Early movement guidance and referral for swelling or stiffness can help. Your rehabilitation plan should match your wound and reconstruction.
Living well after surgery
Use your arm gradually as advised, maintain skin care, and seek prompt advice for spreading redness, heat, or fever. New heaviness, tightness of jewellery, or persistent swelling should be assessed early. Discuss practical advice about blood-pressure checks and needle procedures with your team rather than avoiding necessary care. Do not start a compression sleeve without an appropriate assessment and fitting.
