Testicular cancer is the most common cancer in American males between the ages of 15 and 34, occurring most frequently in men between the ages of 20 and 39. Compared to other types of cancer, however, testicular cancer is rare and accounts for only 1 percent of all cancers in men in the United States.
Testicular cancer is also one of the most treatable and curable forms of cancer, making the risk of dying from this cancer very low. Regular testicular self-examinations can help identify growths early when the chance for successful treatment of testicular cancer is highest.
