Testicular Cancer

This illustration drawn from an electron micrograph image shows testicular cancer. The testes are positioned in the scrotum beneath the penis and are the site of sperm production. Testicular cancer occurs as a result of abnormal growth of germ cells (the cells that mature to become sperm). Age, Race and testicular development can all contribute to testicular cancer but it is still not clear what causes this abnormal growth of cells. Testicular cancer can be recognised by an unusual lump or enlargement of the testicle or pain or discomfort in the groin area. Testicular cancer is quite rare but most common in men between 15-34 years of age, depending on the stage of progression it is highly treatable.
