Types of testicular cancer

There are two main types of testicular cancer – seminomas and teratomas. They may be called germ cell tumours. Occasionally testicular tumours can be a mix of both types.

  • Seminomas most commonly occur in men between 25 and 55 years of age.
  • Teratomas usually affect younger men – from 15 to about 35 years.

Sometimes a type of cancer called non-Hodgkin lymphoma can occur in the testicle. This would be treated as a non-Hodgkin lymphoma.

Other rare types of testicular tumour are Leydig and Sertoli cell tumours.
