Testicular Cancer: Overview

The testicles (testes) are located inside the scrotum, a loose bag of skin underneath the penis. They produce male sex hormones and sperm cells for reproduction.  Testicular cancer is the most common cancer in American males between the ages of 15 and 34. This cancer is even more common in males whose testicles have not both descended into the scrotum (undescended testicle).

Testicular cancer is highly treatable when diagnosed early. The most common initial finding is a lump or enlargement which can be felt in a testicle. Therefore, regular testicular self-examinations are essential in identifying dangerous growths early, when the chance for successful treatment of testicular cancer is highest.  Although most patients can be cured even when the cancer has spread to other areas, early detection makes treatment much less rigorous.
