Testicular Cancer

What are the different types of testicular cancer?

There are two main types of testicular cancer:

1. Germ cell tumours: These account for about 95% of testicular cancers. They develop from the cells that produce sperm. Germ cell tumours are divided into two subtypes:
• Seminomas: These are slower-growing cancers and usually occur in men aged 25 to 45.
• Non-seminomas: These tend to grow and spread more quickly and are more common in younger men in their late teens to early 30s.
  
  
2. Stromal tumours: These develop in the supportive and hormone-producing tissues of the testicles. Stromal tumours are less common and are usually benign (non-cancerous).
