NCI source

Last reviewed: 2026-07-07

The short answer

Testicular cancer is staged from I to III based on whether it is confined to the testicle, has reached lymph nodes, or has spread to distant sites. Tumor marker blood levels are also part of staging. Cure rates are high at every stage.

  • Testicular cancer is staged from I to III.

  • Stage I is confined to the testicle; stage III has spread to distant sites.

  • Blood levels of tumor markers are part of staging.

  • Cure rates are very high at every stage.

The full explanation.

The simple version

Testicular cancer is staged from I to III based on how far it has spread. A distinctive feature is that blood levels of tumor markers are part of staging. Cure rates are very high at every stage.

What the stages mean

In simple terms:

  • Stage I — confined to the testicle
  • Stage II — spread to nearby lymph nodes in the abdomen
  • Stage III — spread to distant lymph nodes or organs

Tumor markers

Certain proteins in the blood can rise with testicular cancer. Their levels are considered in staging and are also used to track how well treatment is working over time.

Blood tumor marker levels are part of testicular cancer staging.

High cure rates

Testicular cancer has very high cure rates at every stage, including when it has spread, thanks to effective surgery and chemotherapy. The stage guides what treatment is recommended after surgery and reflects the outlook.

Common questions

How is testicular cancer staged?

It uses stages I to III, based on whether the cancer is confined to the testicle (I), has spread to nearby lymph nodes (II), or has spread to distant lymph nodes or organs (III). Tumor marker blood levels are also considered.

What are tumor markers in staging?

Certain proteins in the blood can rise with testicular cancer. Their levels help with staging and with tracking how treatment is working.

Are cure rates high even if it has spread?

Yes. Testicular cancer has very high cure rates at every stage, including when it has spread, thanks to effective surgery and chemotherapy.

Why does the stage matter?

The stage guides what treatment is recommended after surgery — such as surveillance, chemotherapy, or radiation — and reflects the outlook.
