How is malignant melanoma treated, and are there any new treatments that are in trials?

Surgery is the most common treatment for early stages of melanoma.
If the melanoma has spread to the lymph nodes or beyond to other internal organs, additional treatments including chemotherapy, and radiation therapy are available.

On March 25, 2011, the Food and Drug Administration (FDA) approved a breakthrough melanoma treatment called Yervoy (ipilimumab). It’s the first therapy proven to extend overall survival for advanced stage melanoma patients. This is this the first melanoma drug to receive FDA approval in 13 years.
