The key idea is that testicular cancer is staged using the TNM system to describe the extent of the primary tumor, nodal involvement, and distant metastasis, with serum tumor markers (AFP, hCG, LDH) guiding risk classification and monitoring. For imaging, a scrotal ultrasound is the first step to evaluate the testicular lesion and distinguish intratesticular from extratesticular masses. To determine the stage, CT or MRI of the abdomen and pelvis is obtained to assess retroperitoneal lymph nodes, where spread often occurs first, and chest imaging (chest X-ray or CT) screens for lung metastases. These imaging studies, together with tumor marker levels, help classify risk and guide treatment decisions. The other options don’t fit because staging isn’t determined by age or histology alone, imaging isn’t limited to just the scrotum, and PET-CT isn’t routinely essential for initial staging.
