Testicular cancer refers to cancer that develops within one or both of the testicles. Testicular cancer most commonly forms in germ cells, which are cells that produce sperm.
The two main types of testicular cancer include:
- Seminoma testicular cancer – the tumour does not include any subtypes. This typically grows more slowly compared to non-seminoma testicular cancer
- Non-seminoma testicular cancer – a rarer cancer where the tumour contains at least one of the following subtypes: teratoma, choriocarcinoma, yolk sac tumour and embryonal carcinoma, and develops more quickly than seminoma cancers
Testicular cancer is an uncommon cancer which affects 59 Singaporean men each year. However, it is most prevalent in men aged between 20 and 40 years.
