Cancer Home > Testicular Cancer Staging
The following stages are used to describe the extent of testicular cancer:
- Stage 0
- Stage I
- Stage II
- Stage III
In stage 0, abnormal cells are only found in the tiny tubules where the sperm cells begin to develop. The abnormal cells do not invade normal tissues and all tumor markers are normal. Stage 0 testicular cancer is also called a precancerous condition or carcinoma in situ.
Stage I is divided into stage IA, stage IB, and stage IS. The testicular cancer stage is determined after a radical inguinal orchiectomy is performed.
In stage IA, the cancer is in the testicle, the epididymis, and the cancer may have spread to the inner layer of the membrane surrounding the testicle. All tumor marker levels are normal in stage IA.
In stage IB:
- The cancer is in the testicle, the epididymis, and has spread to the blood or lymph vessels in the testicle
- The cancer has spread to the outer layer of the membrane surrounding the testicle
The cancer is in the spermatic cord or the scrotum and may be in the blood or lymph vessels of the testicle.
All tumor marker levels are normal in stage IB.
In stage IS, the cancer is found anywhere within the testicle, spermatic cord, or the scrotum, and:
- All tumor marker levels are slightly above normal
- One or more tumor marker levels are moderately above normal or high.
