How do doctors confirm a suspected testicular cancer diagnosis?

In short: A firm mass in the scrotum is the most common sign, but a visual exam is only the beginning. To distinguish between benign conditions and malignancy, specialists rely on a combination of blood markers, advanced imaging, and a definitive surgical tissue analysis.

The diagnostic journey often begins when a primary care physician or urologist detects a firm mass during an examination. While many lumps are benign, doctors must rule out various etiologies. If the diagnosis remains uncertain, a scrotal ultrasound may be used to determine if a mass is located inside or outside the testicle; masses found inside are more likely to be cancerous.

Beyond imaging, clinicians utilize blood tests to detect specific tumor markers—proteins produced by cancer cells. These include lactate dehydrogenase (LDH), beta human chorionic gonadotropin (beta hCG), and alpha-fetoprotein (AFP). While elevated levels of these substances do not definitively mean a patient has cancer, they provide vital clues that help specialists identify the specific type of cancer present.

The distinction between the two primary types of germ cell tumors is critical for determining treatment. Seminomas tend to occur at an older age and generally grow and spread more slowly. In contrast, nonseminomas—which include subtypes like choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumor—often appear earlier in life and tend to grow and spread more quickly.

Ultimately, a definitive diagnosis requires a tissue sample. This is typically achieved through a radical inguinal orchiectomy, a procedure where the testis is removed and sent to a pathologist. The pathologist examines the tissue to confirm the presence of cancer, identify the specific cell type, and determine the cancer's stage to see how extensively it has spread, such as to the retroperitoneal lymph nodes in the abdomen.
