General Information

 Male genital glands (gonads) that produce the male reproductive cells, or spermatozoa,    and the male hormone testosterone


 Each testis is surrounded by a thick fibrous capsule and is composed of many small,    thin, coiled tubes called seminiferous tubules


 Testicular cancers usually grow from cells in the gonads that actually create the sperm


 Tumors of both testicles are uncommon

 Tend to occur in younger men

 Testicular cancers are uncommon but can be very malignant

 Death is unusual now but may be caused by bulky, wide-spread disease


 Early detection can result in a complete cure and less treatment

 Very few benign tumors are found in the testes so all lumps should be checked    immediately


 Often lumps are confused with inflammatory conditions of the adjacent epididymis
