Final answer:
The preferred treatment for testicular cancer is surgery to remove the affected testis, often followed by radiation therapy and/or chemotherapy, depending on whether the cancer has spread.
Step-by-step explanation:
The treatment of choice for a patient diagnosed with testicular cancer is generally surgery to remove the affected testis. Testicular cancer has a very high cure rate, and when diagnosed at an early stage and treated with surgery, it has nearly a 100 percent five-year survival rate. The surgery is often adequate to cure the cancer if it has not spread, and the remaining healthy testis can continue to maintain fertility and hormone production. Following surgery, radiation therapy and/or chemotherapy may be employed to eradicate any residual tumor cells. The decision to use additional treatments like radiation or chemotherapy depends on the stage of cancer and whether cancer cells have spread beyond the testis.
