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.

The full explanation.
The simple version
Testicular cancer is staged from I to III. The stage shows how far the cancer has spread. A distinctive feature of testicular cancer staging is that blood levels of tumor markers are built directly into the stage. Cure rates are very high at every stage.
What the stages mean
- Stage I — cancer is found only in the testicle. It has not reached lymph nodes or other organs. This stage has substages based on whether the cancer has grown into blood vessels and whether tumor marker levels are normal or slightly raised.
- Stage II — cancer has spread to lymph nodes in the abdomen, called retroperitoneal lymph nodes. Substages depend on how large those lymph nodes are.
- Stage III — cancer has spread to distant lymph nodes or organs, such as the lungs, liver, or bone. Substages depend partly on how high tumor marker levels are.
Blood tumor marker levels are built directly into testicular cancer staging.
Tumor markers and the S category
Three blood tests matter for staging: AFP, beta-hCG, and LDH. Together they form what doctors call the S category. Normal or only slightly raised levels suggest a lower burden of disease. Sharply raised levels point to more advanced disease, even at the same anatomical stage. These same tests are repeated during and after treatment. Falling levels are a reassuring sign that treatment is working.
How the stage is determined
Staging starts with removal of the affected testicle, since that tissue confirms the type and how far the cancer has grown locally. CT scans of the abdomen and chest look for lymph node or organ involvement. Blood tests for tumor markers are drawn both before and after surgery, since some markers should fall after the testicle is removed if there is no cancer left elsewhere.
Why stage still allows for very high cure rates
Testicular cancer has some of the highest cure rates of any cancer, including when it has spread to distant sites. Even stage III testicular cancer, treated with chemotherapy and sometimes further surgery, is often curable. This is unusual among cancers and is one reason doctors emphasize that a testicular cancer diagnosis, even an advanced one, is not the same as facing a poor outlook.
Why the stage still matters
Even with high cure rates across the board, stage shapes exactly what treatment looks like. Lower stages may call for surveillance or a shorter course of chemotherapy. Higher stages usually call for more intensive chemotherapy, sometimes combined with surgery to remove any remaining lymph node masses after chemotherapy is complete.
What to ask your team
Ask what stage your testicular cancer is. Ask what your tumor marker levels show, and how they are trending. Ask what treatment your stage calls for after surgery. Ask what your expected outlook is, understanding that testicular cancer is treatable at every stage.

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.

How this page was created
Cancer Explained does not originate medical claims. Every page restates guidance already published by the National Cancer Institute, the CDC, the USPSTF and the FDA, in plain language, with the source cited so you can check the original yourself. AI does the translating and organizing; automated checks test claims, citations, clarity and safety before anything publishes. We do not employ clinicians and do not intend to — our work is translation and navigation, not clinical judgment. Nothing here is personal medical advice, and no page can account for your particular situation.
Editorial status — Source checked. This page was written with AI assistance and checked line by line against the sources listed on it. That confirms the sources support what the page says. It is not a medical review, and it does not confirm the page is complete or right for your situation.
General education — varies by person. Answers genuinely differ between people. This page explains what commonly varies and points you to your care team for your situation.
Human medical review: not completed. Pages here are not signed off by a clinician before they publish. That is not an oversight we are quietly working around: we restate published guidance and cite it, so the authority belongs to the source rather than to us, and every page names where its claims come from — you can verify us instead of trusting us. Where a volunteer clinician has reviewed a page, their name and credentials appear on it; where no name appears, no clinician has checked it. We are glad to have reviewers and are recruiting them, and we do not hold pages back waiting for one. Use this site to understand your situation and to ask better questions of the people treating you.
