The basic surgical procedures are orchiectomy and retroperitoneal lymphatic dissection. Radiation therapy is extremely sensitive to seminoma, embryonal carcinoma and malignant teratoma are less sensitive to radiation, and chorioepithelial carcinoma is extremely insensitive to radiation. Testicular tumors are effective for chemotherapy, which is generally considered to be more effective for seminoma and also effective for embryonal and chorioepithelial carcinoma, especially when several drugs are combined, and less effective for teratoma, and for advanced or recurrent cases. The side effects of treatment depend on the type of treatment and vary from person to person. Most testicular cancer patients can be cured. If testicular cancer is detected early, the treatment does not need to be very aggressive. As a result, treatment does not cause many side effects and the chance of cure is very high.
