Testicular cancer occurs when malignant cells form in the tissues of one or, less commonly, both testicles. It affects approximately one in 250 males at some point in their lifetimes.
In the United States, the American Cancer Society estimates approximately 9,760 new cases of testicular cancer and around 500 deaths from the disease in 2024. Since testicular cancer is typically treatable, the lifetime risk of a man dying from it is very low, roughly one in 5,000.
