Testicular Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Testicular Cancer
There are three ways that cancer spreads in the body.
Cancer can spread through tissue, the lymph system, and the blood:
- Tissue. The cancer spreads from where it began by growing into nearby areas.
- Lymph system. The cancer spreads from where it began by getting into the lymph system. The cancer travels through the lymph vessels to other parts of the body.
- Blood. The cancer spreads from where it began by getting into the blood. The cancer travels through the blood vessels to other parts of the body.
Cancer may spread from where it began to other parts of the body.
When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor) and travel through the lymph system or blood.
- Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor (metastatic tumor) in another part of the body.
- Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body.
The metastatic tumor is the same type of cancer as the primary tumor. For example, if testicular cancer spreads to the lung, the cancer cells in the lung are actually testicular cancer cells. The disease is metastatic testicular cancer, not lung cancer.
The following stages are used for testicular cancer:
Stage 0 (Carcinoma in Situ)
In stage 0, abnormal cells are found in the tiny tubules where the sperm cells begin to develop. These abnormal cells may become cancer and spread into nearby normal tissue. All tumor marker levels are normal. Stage 0 is also called carcinoma in situ.
In stage I, cancer has formed. Stage I is divided into stage IA, stage IB, and stage IS and is determined after an inguinal orchiectomy is done.
- In stage IA, cancer is in the testicle and epididymis and may have spread to the inner layer of the membrane surrounding the testicle. All tumor marker levels are normal.
- In stage IB, cancer:
All tumor marker levels are normal.
- is in the testicle and the epididymis and has spread to the blood vessels or lymph vessels in the testicle; or
- has spread to the outer layer of the membrane surrounding the testicle; or
- is in the spermatic cord or the scrotum and may be in the blood vessels or lymph vessels of the testicle.
- In stage IS, cancer is found anywhere within the testicle, spermatic cord, or the scrotum and either:
- all tumor marker levels are slightly above normal; or
- one or more tumor marker levels are moderately above normal or high.
