What is the term for advanced cancer that has spread from the testes to other organs?

The term "Metastatic Testicular Cancer" specifically refers to advanced testicular cancer that has spread beyond the testes to other organs. In the context of cancer, "metastasis" describes the process whereby cancer cells break away from the original tumor and travel through the bloodstream or lymphatic system to form new tumors in other parts of the body.

When testicular cancer progresses to this stage, it presents unique challenges in terms of treatment and prognosis. The ability to identify metastatic disease is crucial for determining the appropriate therapeutic approach and for understanding the extent of the disease. In contrast, terms like "Testicular Carcinoma" and "Germ Cell Tumor" refer to types of testicular cancer but do not specifically indicate whether the cancer has spread. "Semen Analysis" pertains to evaluating male fertility and does not have a direct connection to cancer staging or the spread of cancer. Therefore, "Metastatic Testicular Cancer" is the most accurate term to describe the condition in the question.
