Diagnosis is by biopsy of the scrotal lesion. There are several different tests involved in staging, including MRI of the scrotum and abdominopelviscrotal ultrasound. Ray and Whitmore proposed a staging system based on the level of metastasis. It is the most commonly used system. There are four stages of the cancer, listed as Stage A through to Stage D. Under Stage A there are two substages, Stage A1 and Stage A2. Stage A1 is when the disease is localized in the scrotum. Stage A2 is when the disease moves to surrounding areas, including the penis, testis, pubic bone, and perineum. During Stage B, the disease metastasizes regionally. At this point in the disease, the cancer and/or tumor is resectable. At Stage C, the disease further metastasizes, however, at this point is it no longer resectable. Distant metastasis occurs during Stage D of the disease. At this point, it moves past the regional nodes, which is rare.
