Testicular cancer

Testicular cancer

What is testicular cancer?

Cancer that develops in a testicle is called testicular cancer or cancer of the testis. Usually only one testicle is affected, but in some cases both testicles are affected. Most testicular cancers start in the cells that develop into sperm, which are called germ cells.

Sometimes testicular cancer can spread to lymph nodes in and around the testicles and abdomen, or to other parts of the body.
