Overview

Testicular cancer is a rare type cancer accounting about 0.5% of all new cancer cases in U.S. In 2018, the estimate prevalence of testicular cancer is approximately 9,310 new cases of testicular cancers in the United States. The incidence of testicular cancer is approximately 5.7 per 100,000 men per year based on 2011-2015 report in the United States. The majority of cases are reported in New Zealand. Testicular cancer commonly affects more white males than any other races and black males are less affected by it. Testicular cancer is commonly affects men aged 20-44 years old and median age is 33 years old.

Epidemiology and Demographics

Incidence

  • The incidence of testicular cancer is approximately 5.7 per 100,000 men per year based on 2011-2015 report in the United States.[4]

Age

Mortality rate

  • The 5 years of survival rate for patients with testicular cancer are 95.3% in 2008-2014.[4]

Race

  • Testicular cancer is more common in white males compared to other races.[4]
  • The incidence of testicular cancer in African American is lower than that among white people;[5] however, African American subjects tend to present at later stages of the disease due to a delayed presentation.[5]
  • Shown below is a table depicting the age-adjusted incidence of testicular cancer by race in 2011-2015 in the United States.[4]
All Races White Black Asian/Pacific Islander Hispanic
Age-adjusted incidence 5.7 per 100,000 6.8 per 100,000 1.5 per 100,000 2.3 per 100,000 5.3 per 100,000

Developed Countries

  • The highest rates of incidence in New Zealand, followed by United Kingdom, Australia, Sweden, United States, Poland, and Spain.[1]

Developing Countries

  • Testicular cancer is uncommon in Asia and Africa.[3]
  • The lowest incidence of testicular cancer is in India.[1]
