What are the types of testicular cancer?

Knowing what type of testicular cancer you have can help your doctors plan your treatment and aftercare.

Germ cell tumours

Most testicular cancers are germ cell tumours. Germ cells are cells that make sperm. There are two types of germ cell tumours, known as seminomas or non-seminomas.

Seminomas

These usually develop between the ages of 30 and 50. They tend to grow slowly and respond very well to treatment. With a seminoma there is a lower risk of cancer having spread at the time of diagnosis.

Non-seminomas

These tend to develop earlier in life than seminomas. They peak in those aged 20-35. Non-seminomas can include cells called teratoma, embryonal, yolk sac and choriocarcinoma.  Non-seminoma tumours are more likely to need additional treatment after surgery. These cancers are still highly curable in most cases, even if they have spread.
