Should I talk to my doctor about my germ cell tumor (childhood) symptoms?

Talk to your doctor if you experience persistent symptoms, even if they could be caused by something else. Any symptoms that last for a long time or recur frequently could be signs of a serious disease, not only germ cell tumors. If you feel or see unusual lumps anywhere on your body, especially on your abdomen, tailbone, or testicles, let your doctor know immediately.
