Germ Cell Cancer

Rare but treatable. Know the signs.

Germ cell tumours can occur in the testicles, ovaries, or other parts of the body. They develop from the cells that make eggs or sperm. While rare, they primarily affect adolescents and young adults.

Symptoms to Look Out For

Lump or swelling

A painless lump, usually in the testicle or ovary

Abdominal pain

Pain in the lower abdomen or back

Breathlessness

Shortness of breath or persistent cough if cancer has spread to the chest

Fatigue and weight loss

Unusual tiredness and unexplained weight loss

Symptoms vary depending on where the germ cell tumor is located. Always see your GP if you notice unusual changes.

Risk Factors

Undescended testicle

Boys born with an undescended testicle (cryptorchidism) have a higher risk of testicular germ cell tumours, even if surgically corrected

Previous germ cell tumour

If you've had a germ cell tumour in one testicle or ovary, there's an increased risk of developing one in the other

Family history

Having a close relative (father or brother) with a germ cell tumour slightly increases risk

Klinefelter syndrome

This genetic condition affecting males is associated with a higher risk of mediastinal (chest) germ cell tumours

Having one or more risk factors doesn't mean you will develop germ cell cancer. Many people with risk factors never develop the disease.
