When is neck dissection recommended for head and neck cancer?

A neck dissection removes selected lymph nodes and nearby tissue from one side or both sides of the neck, depending on the cancer and its spread. It may be performed with removal of the primary tumour or after other treatment. The extent is chosen to balance cancer control with preservation of nerves, muscles and blood vessels whenever possible.

The team reviews scans, examination findings, tumour location, lymph-node features and previous treatment before advising surgery. Discuss swallowing, shoulder movement, neck sensation, scars, drains and recovery. Ask whether radiotherapy, chemotherapy or observation is an alternative or may be needed after surgery.

After surgery, seek urgent help for breathing difficulty, rapidly increasing neck swelling, uncontrolled bleeding, fever with worsening redness, or new severe weakness. Before treatment, report a rapidly enlarging neck lump, new swallowing difficulty or noisy breathing without delay.

Ask which lymph-node areas would be removed, why this extent is advised, how shoulder and neck function may be affected, what support is available, and how pathology results will guide the next treatment.
