If your melanoma has spread to nearby lymph nodes you will have further surgery to remove them. This is called lymph node dissection.
You will need to be in hospital to have your lymph nodes removed. You’ll usually need to stay in hospital for 3–5 days. The surgery is carried out under a general anaesthetic.
The operation you have and its side effects will depend on the lymph nodes being removed. For example, if the melanoma was in your leg, a cut (incision) is made in the groin on the affected side to remove the lymph nodes. If the melanoma was in your arm, the lymph nodes in your armpit on the affected side will be removed. The nodes in your neck will be removed if you had a melanoma anywhere on your face or head or in the neck area. Your specialist doctor or nurse will tell you more about what to expect.
