One example doctors and a few others have referenced to is Lance Armstrong. He also had testicular cancer that spread. In October 1996, he was diagnosed with testicular cancer that had spread to his brain and lungs. His cancer treatments included brain and testicular surgery and extensive chemotherapy. In February 1997, he was declared cancer-free and the same year he founded theLance Armstrong Foundation for cancer support. 


 Here are a  few things that I have read on the internet and like.

Compared with other types of cancer, testicular cancer is rare. But testicular cancer is the most common cancer in American males between the ages of 15 and 34. Testicular cancer is highly treatable, even when cancer has spread beyond the testicle. Depending on the type and stage of testicular cancer, you may receive one of several treatments, or a combination.

Most men with testicular cancer can be successfully treated, especially when the cancer is detected early. Even testicular cancer that has spread may respond well to treatment.

This looks like excellent information as well:
