Surgery is mainly used to help control the growth of advanced melanoma and relieve symptoms, but usually only when it has not spread very much. It can be used to treat melanoma that has spread to:
- areas of skin distant from the original melanoma
- lymph nodes distant from the original melanoma
- the brain
- the liver (but only if the cancer has spread to a single place in the liver)
- the lungs (but only if the cancer has spread to a single place in the lungs).
Surgery can sometimes be used to remove a secondary tumour. This is called a metastasectomy.
