What Are the Stages of Testicular Cancer?
Staging is the term oncologists use to define where testicular cancer is located and how much it has spread. Once the stage of testicular cancer is determined, your physician can recommend a particular course of treatment.
Most cancer teams use the system developed by the American Joint Committee on Cancer, known as the TNM staging system.
T = Tumor: Where is the primary tumor and how large is it?
N = Nodes: Has the tumor spread to nearby lymph nodes?
M = Metastasis: Has cancer spread to other parts of the body?
For each letter, there are five numbered stages, from 0 to 4, depending on how much the cancer has spread. The lower the number, the more the cancer cells look like normal cells and the easier they are to treat and cure. A higher number means it has spread more deeply.
The place where cancer originates is called the primary site. Cancer can spread from the primary site to other parts of the body. It’s important to understand that even if testicular cancer is found in other parts of your body, it’s still considered testicular cancer. For instance, if colon cancer has spread to the liver, it’s called metastatic colon cancer, not liver cancer.
For testicular cancers that have spread outside the testicles, physicians also use risk groups, which are based on how easy or hard it is likely to be to treat these cancers successfully. These risk groups depend on whether the cancer is a seminoma or nonseminoma, the extent and location of the cancer and serum tumor marker levels.
Be sure to talk to your physician about your particular stage of the cancer and how that will impact your treatment.
