germ cell cancergerm cell cancer


  • A germ cell tumour is a tumour that develops from reproductive cells. They are sperm cells in men and egg cells in women. They usually develop in the testicles or ovaries but can grow in other areas of the body – however, cancers that develop from germ cells in other parts of the body are very rare.
  • The medical name for germ cell tumours that develop outside of the ovaries or testicles (the gonads) is extragonadal germ cell tumour (EGGCT). For example, germ cell tumours can start in the brain, at the back of the abdomen (retroperitoneum) or the chest (mediastinum).
  • The mediastinum is the area in the centre of the chest, between the lungs. It contains the heart, windpipe (trachea), food pipe (oesophagus), large main blood vessels and the lymph nodes that surround the heart. The mediastinum is the most common place for extragonadal germ cell tumours to develop.


  • Doctors aren’t certain how these germ cell tumours develop in the mediastinum. There are some theories about how the cells get outside the testicle and ovary – these include:
  • The cancer develops from very early cells that became misplaced during our development in the womb
  • The cancer started in the testicle or ovary and spread at a very early stage, but the original cancer has either disappeared or is too small to find


  • Many people with a tumour in the mediastinum don’t have any symptoms. The doctor might spot the tumour on a chest X-ray you had for another reason. If symptoms are present they might include:
  • Shortness of breath
  • Pain in the chest
  • A persistent cough
  • Raised temperature
  • Unexplained weight loss
  • Night sweats
