Does neck dissection treat head and neck cancer?

A neck dissection is an operation to remove lymph nodes and nearby tissue from one side or both sides of the neck. It may remove known cancer, reduce the chance that hidden cancer remains in the nodes, or provide tissue for diagnosis and staging. The exact operation depends on the primary cancer's location, scans, examination findings, and which neck structures need protection. It does not remove a tumour in the mouth, throat, nose, or voice box by itself.

The head and neck cancer team may combine neck dissection with removal of the primary tumour, radiotherapy, chemotherapy, or other medicines. Ask which lymph-node levels are involved, what the operation is intended to achieve, and how it fits with other treatment. Before surgery, discuss shoulder movement, neck sensation, swallowing, wound care, drains, and the expected recovery plan. Rehabilitation may include physiotherapy or specialist support.

Follow the surgical team's instructions and seek urgent help for breathing difficulty, sudden neck swelling, uncontrolled bleeding, or severe chest pain. Contact the team about fever, increasing redness, pus, worsening pain, a leaking wound, or new difficulty swallowing. Report shoulder weakness or reduced arm movement so rehabilitation can be arranged.

Is the goal to remove known lymph-node cancer, assess the nodes, or both? Which structures may be affected? Will I need treatment before or after surgery, and what support will help with shoulder and neck recovery?
