What are the prognosis and survival rates for melanoma by stage?
Survival rate. A person’s response to treatment will affect their chance of survival. According to the American Cancer Society, the 5-year survival rate for stage 4 melanoma is 15–20 percent. This means that an estimated 15–20 percent of people with stage 4 melanoma will be alive 5 years after diagnosis.
