What does metastatic testicular cancer refer to?

Metastatic testicular cancer specifically refers to advanced cancer that originates in the testes and then spreads to other parts of the body, such as lymph nodes, lungs, liver, or even the brain. This characteristic distinguishes it from localized testicular cancer, which has not yet spread beyond the testicles. Understanding this aspect is crucial, as the management and treatment strategies differ significantly depending on whether the cancer is localized or metastatic.

The other options, while discussing cancer in different anatomical contexts, do not apply to testicular cancer. They refer to other cancers or stages of cancer that do not involve the progression from testicular tissue to systemic involvement. Recognizing that metastasis indicates advanced disease is important for both treatment and prognosis considerations.
