Symptoms of germ cell tumours outside the brain may include:

  • a lump in the belly, lower back or testicle
  • pain in the belly
  • fever
  • constipation
  • in girls, not having periods or having unusual bleeding from the vagina.

Germ cell tumours in the brain may cause symptoms such as:

  • extreme thirst
  • urinating often
  • headaches
  • nausea or vomiting
  • changes in vision
  • loss of appetite
  • weight loss
  • tiredness
  • early or late puberty.

Symptoms of germ cell tumours depend on:

  • where the tumour is
  • how big it is
  • whether it produces hormones.

Many conditions can cause the symptoms above, not just cancer. If your child has any of these symptoms and you are worried, talk to your child’s doctor. The earlier cancer is found, the better.
