Axillary lymph node dissection is mostly seen in patients with malignant tumors, especially breast cancer patients who need radical resection, but they are also prone to common complications after surgery. First, lymphoma in the upper limbs will manifest as swelling of the limbs and also numbness, even with obvious congestion and redness changes. Second, local scar tissue hyperplasia can also lead to pain and the patient will experience itching. Third, there are some patients who have axillary vascular and nerve invasion and need local skeletonization during surgery, which can also lead to collateral damage and also symptoms of nerve damage, so the patient will also show numbness of the limb as well as limited activity and abnormal sensation. Fourth, after surgery, recurrence is also likely to occur, especially at the site of lymph node dissection, which should be followed up and observed regularly, and if necessary, local radiation therapy and systemic intravenous chemotherapy are also required after surgery.
