Testicular cancer is a malignancy that originates in a man’s testicles. If detected early, this cancer is highly curable. The disease is rare but found most often in younger men. Typically, testicular cancer is limited to one testicle.
Most men diagnosed with testicular cancer are between ages 15 and 35. In the United States, 7,000 men per year find out they have testicular cancer; 300 men die annually from the disease. However, the five-year survival rate for testicular cancer is more than 95 percent for all stages, which means that early detection is important so that treatment can begin as quickly as possible.
The cause of testicular cancer is unknown. However, men with an undescended testicle, surgically corrected or not, are at an increased risk of developing the disease. (An undescended testicle is one that does not naturally pass from the abdomen to the scrotum before birth.)
