How is Testicular cancer diagnosed?

Testicular cancer is primarily diagnosed through a combination of a physical examination, scrotal ultrasound, and blood tests for tumor markers (AFP, beta-hCG, and LDH). While testicular cancer is highly treatable when caught early, the diagnostic process involves confirming the malignancy through surgical removal of the affected testicle, known as an orchiectomy, followed by pathological analysis.

What is the diagnostic process for testicular cancer?

The diagnostic journey for testicular cancer typically begins with the discovery of a painless lump or swelling in the scrotum. Because this can mimic other conditions, doctors use a structured approach to rule out benign issues. If an abnormality is detected, the diagnostic steps include:

• Physical Exam: A urologist examines the scrotum to assess the size, consistency, and location of the mass.


• Scrotal Ultrasound: This is the gold-standard imaging tool to determine if a mass is solid (suggestive of testicular cancer) or fluid-filled (like a hydrocele).


• Serum Tumor Markers: Blood tests measure levels of alpha-fetoprotein (AFP), human chorionic gonadotropin (beta-hCG), and lactate dehydrogenase (LDH), which are often elevated in testicular cancer.


• Radical Inguinal Orchiectomy: Unlike many other cancers, a biopsy is rarely performed due to the risk of spreading cells. Instead, the testicle is surgically removed and analyzed by a pathologist to confirm the diagnosis and type of testicular cancer.

Which specialists are involved in diagnosing testicular cancer?

A urologist is the primary specialist who manages the diagnostic phase of testicular cancer. If the pathology report confirms malignancy, a medical oncologist or radiation oncologist will join the care team to determine the stage and treatment plan. We recognize that waiting for these appointments can be incredibly stressful; our DiseaseMaps.org community of 4 members understands the anxiety of this "diagnostic window."

What conditions can be confused with testicular cancer?

It is common for patients to feel frustrated if initial symptoms are misdiagnosed. Testicular cancer can often be confused with benign conditions such as epididymitis (inflammation of the epididymis), orchitis (testicular inflammation), hydroceles (fluid buildup), or spermatoceles. If you are experiencing persistent scrotal pain or swelling that does not resolve, it is vital to consult a urologist who specializes in urologic oncology to ensure an accurate and timely diagnosis.

Next steps

• Consult a urologist immediately if you notice a firm, painless lump on a testicle.


• Request a referral to a high-volume cancer center if your local provider is unfamiliar with testicular oncology.
