Testicular Cancer

Testicular cancer nearly always starts in the germ cells of the testicles, which produce immature sperm. The two main types of testicular germ cell tumors are seminomas and nonseminomas. These two types of cancer are treated differently as seminomas are more sensitive to radiation and chemotherapy while nonseminomas are more often treated with surgery. Additionally, nonseminomas tend to grow and spread more quickly than seminomas.

Cancer of the testes is the most common cancer in men 20 to 34 years old. Risk factors of testicular cancer include a family or personal history of testis cancer as well as an undescended testis.

According to the National Cancer Institute’s Surveillance, Epidemiology, and End Results (SEER) Program, it was estimated that 9,810 men would be diagnosed with testicular cancer in the United States in 2026 and about 630 would die of the disease. The five-year relative survival rate is 94.6%.
