Stage 4 melanoma has a 15% survival rate over 5 years. Much less if near the lymph nodes.
Stage 4 cancer would mean that the cancer has invaded the lymph nodes already. Cancer invades locally and then goes to lymph nodes and then to other organs in the body. If the cancer is in the lymph node, it'll mean the cancer is either stage 2 or 3. Stage 4 of any cancer is cancer that has metastasized or gone to other organs.
I'm not sure about the actual survival rate numbers for melanoma but those look about right for stage 4 melanoma. It is a bad ass disease. :(
