Prognosis

• The prognosis and treatment options depend on the following:

• The stage of the cancer (the size of the tumor and whether it has spread to the lymph nodes or other parts of the body).
• Where the cancer is in the body.
• Whether the cancer has just been diagnosed or has recurred.
• The patient's age and general health.
• Prognosis also depends on how deeply the tumor has grown into the skin.

• Patients who present with no metastases and a negative sentinel lymph node biopsy have a good prognosis when treated with surgery and radiotherapy (approximately 90% survival at five years).
