The prognosis is determined by histologic analysis the tumor. Tumor thickness, presence of ulceration, number of lymph nodes involved and anatomic location determine survival rates. Detailed tables are published with these data.

Patient’s was localized lesions that have been completely excised and a 5 year survival rate of over 90%.

  • Melanoma in situ: 100% survival at 5 years and 10 years
  • Lesions ≤1 mm: 91%–95% at 5 years; 83%–88% at 10 years
  • Lesions 1.01–2 mm: 77%–89% at 5 years; 64%–79% at 10 years
  • Lesions 2.01–4 mm: 63%–79% at 5 years; 51%–64% at 10 years
  • Lesions >4 mm: 45%–67% at 5 years; 32%–54% at 10 years
