Life expectancy for cancers is often expressed as a 5-year survival rate (the percent of patients who will be alive 5 years after diagnosis). The overall average 5-year survival rate for all patients with melanoma is 92%. This means 92 of every 100 people diagnosed with melanoma will be alive in 5 years.
