Testicular Cancer forms in tissues of the testis (one of two egg-shaped glands inside the scrotum that make sperm and male hormones). Testicular cancer usually occurs in young or middle-aged men. Two main types of testicular cancer are seminomas (cancers that grow slowly and are sensitive to radiation therapy) and nonseminomas (different cell types that grow more quickly than seminomas).

Estimated new cases and deaths from testicular cancer in the United States in 2009:

New cases:  8,400
Deaths:  380
