These symptoms do not necessarily mean that a patient has testicular cancer. Other harmless conditions that mimic the symptoms of testicular cancer include hydrocele, a collection of fluid in the scrotum; epididymitis, a swelling of the epididymis (the structure behind the testis where sperm mature) which may also cause fever and discharge from the penis; and varicocele, varicose veins in the scrotum. Inflammation of the testis can also be related to bacterial and viral infections.
