Testicular cancer occurs in the testicles (testes), which are located inside the scrotum, and is the most common cancer in American males between the ages of 15 and 34. The testicular glands produce male sex hormones as well as sperm for reproduction. The two main types of testicular cancer are seminomas (cancers that grow slowly and are sensitive to radiation therapy) and nonseminomas (different cell types that grow more quickly than seminomas).
Although compared with other types of cancer, testicular cancer is rare and highly treatable, regular testicular self-examinations can help identify growths early, when the chance for successful treatment of testicular cancer is highest.
