Testicular Cancer


Almost all testicular cancers start in the germ cells. The two main types of testicular germ cell tumors are seminomas and nonseminomas. These forms of the disease grow and spread differently and are treated differently. 

Nonseminomas tend to grow and spread more quickly than seminomas. Seminomas are more sensitive to radiation. A testicular tumor that contains both seminoma and nonseminoma cells is treated as a nonseminoma. Testicular cancer is the most common cancer in men 20- to 35-years-old.

Health history can affect the risk of testicular cancer. According to the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program es​timate, 9,310 men will be diagnosed with testicular cancer in the United States and some 400 will die of the disease in 2018.
