Testicular Cancer: About Testicular Cancer
Testicular cancer results when malignant cells develop in the testes, the male reproductive glands located in the scrotum, a sac behind the penis. In adults, the testis (or testicle) is roughly the size of a golf ball. The testis produces sperm and also provides the male sex hormone testosterone. A structure called the spermatic cord (the vas deferens) suspends the testicles within the scrotum and carries sperm into the ejaculate to fertilize an egg.
Testicular cancer is relatively rare. There are 8800 new cases a year in the United States. It is highly treatable and usually curable. Studies show the cure rate in all stages combined to be approximately 95 percent.
