Testicular Cancer Awareness Month

Testicular Cancer Awareness Month

Testicular cancer forms in the testicles. Almost all testicular cancers start in the germ cells. The two main types of testicular germ cell tumors are seminomas and nonseminomas. 

Nonseminomas tend to grow and spread more quickly than seminomas, which are more sensitive to radiation. Health history, including having had an undescended testicle, can affect a man’s risk of testicular cancer.

Other risk factors include:    

  • Having had abnormal development of the testicles.
  • Having a family history of testicular cancer (especially in a father or brother).
  • Being white.

Testicular cancer most often develops in young and middle-aged men and is the most common form of cancer in 20- to 35-year-old men. It is a highly treatable and often curable form of cancer, according to the National Cancer Institute (NCI). 

The NCI’s Surveillance, Epidemiology, and End Results (SEER) Program estimates that in 2021, 9,470 men in the United States were diagnosed with testicular cancer and some 440 died of the disease. 

Testicular cancer remains one of the most treatable cancer types, with over 95 percent of those diagnosed surviving five years.

April is Testicular Cancer Awareness Month. 

The AACR’s mission is to prevent and cure all forms of cancer.
