What Is Testicular Cancer and Who Is Most Commonly Affected?

Testicular cancer is a type of cancer that develops as a result of uncontrolled growth of cells within the testicular tissue. It is most commonly seen in young and middle-aged men. Although it is rarer than many other cancer types, treatment success rates are very high when diagnosed at an early stage. A family history of testicular cancer and certain congenital testicular conditions may be considered risk factors.
