What are the short term and long term side effects of lymph node dissection?
Short term side effects include soreness, stiffness and seroma. A seroma is a mass caused by the localized accumulation of serum, or clear fluid, within a tissue or organ. Long term side effects include lymphedema and numbness under the arm. Lymphedema is an accumulation of fluid that may collect in the arm when lymph vessels are removed. This can cause the arm to swell and become disfigured and painful.
