People diagnosed with Stage IB melanoma have a 5-year survival rate of 92 percent and a 10-year survival rate of 86 percent, according to the ACS. The survival rates for Stage IIA are 81 percent at 5 years and 67 percent at 10 years. At Stage IIB, the 5-year survival rate decreases to 70 percent, and the 10-year survival rate decreases to 57 percent. Stage IIC has a 5-year survival rate of 53 percent and a 10-year rate of 40 percent.

At Stage IIIA, the survival rates slightly increase to 78 percent for 5 years and 68 percent at 10 years, notes the ACA. For Stage IIIB, the 5-year survival rates decrease to 59 percent, and the 10-year survival rate is 43 percent. Stage IIIC has a 5-year survival rate of 40 percent and a 10-year survival rate of 24 percent.

All survival rates are approximate. The ACS also notes that survival rates include people who died of other causes, so the actual melanoma survival rates are possibly higher.
