Overview

The prevalence of melanoma is approximately 150-200 per 100,000 individuals. The majority of patients are diagnosed after the age of 65 years. Melanoma is more common among males and individuals of the Caucasian race.

Epidemiology and Demographics

Prevalence

  • In the United States, the age-adjusted prevalence of melanoma was 187 per 100,000 individuals in 2011.[1]

Incidence

  • The delay-adjusted incidence of melanoma in 2011 was estimated to be 23.21 per 100,000 persons in the United States.[1]
  • In 2011, the age-adjusted incidence of melanoma was 22.74 per 100,000 persons in the United States.[1]

Age

  • While the overall age-adjusted incidence of melanoma in the United States between 2007 and 2011 is 21.3 per 100,000, the age-adjusted incidence of melanoma by age category is:[1]
    • Under 65 years: 12.6 per 100,000
    • 65 and over: 81.1 per 100,000
  • Shown below is an image that demonstrates the delay-adjusted incidence and observed incidence of melanoma by age and gender in the United States between 1975 and 2011. These graphs are adapted from SEER: The Surveillance, Epidemiology, and End Results Program of the National Cancer Institute.[1]

Delay-adjusted incidence and observed incidence of melanoma by age and gender in the United States between 1975 and 2011

Gender

  • There is a slight male preponderance to the development of melanoma.
  • The male to female ratio is approximately 1.2-1.6 to 1.

Race

  • There is a racial preponderance to the development of melanoma, where Caucasian individuals are at a significantly increased risk compared to dark-skinned individuals.
  • Shown below is a table that demonstrates the age-adjusted prevalence of melanoma by race in 2011 in the United States.[1]
All Races White Black Asian/Pacific Islander Hispanic
Age-adjusted prevalence 187 per 100,000 234.5 per 100,000 7.5 per 100,000 11.1 per 100,000 37.9 per 100,000
  • Shown below is an image depicting the incidence of melanoma by race in the United States between 1975 and 2011.[1]
