Testicular cancer usually can be cured if it is detected and treated early. However, this cancer can spread silently and quickly. This means that some men will not be diagnosed until the disease is in an advanced stage.
At one time, testicular cancer could not be cured if it had spread beyond the testicles. Now, testicular cancer is one of the most curable cancers.
Most men with testicular cancer have an excellent prognosis. Men with Stage I disease are very likely to be cured with surgery and radiation therapy. Men with Stage II disease have a very good prognosis following surgery and radiation or chemotherapy. Even men with the most advanced cases have a fair prognosis: More than half of them will be alive five years later.
People who have been cured of testicular cancer involving one testicle have a small risk of developing cancer in the other testicle at some point in their lives.
