How is testicular cancer detected? What are symptoms of testicular cancer?

Comment on this Read 1 Comment

Most testicular cancers are found by men themselves. Also, doctors generally examine the testicles during routine physical exams. Between regular checkups, if a man notices anything unusual about his testicles, he should talk with his doctor. Men should see a doctor if they notice any of the following symptoms:

  • a painless lump or swelling in a testicle


  • pain or discomfort in a testicle or in the scrotum


  • any enlargement of a testicle or change in the way it feels


  • a feeling of heaviness in the scrotum


  • a dull ache in the lower abdomen, back, or groin


  • a sudden collection of fluid in the scrotum

These symptoms can be caused by cancer or by other conditions. It is important to see a doctor to determine the cause of any of these symptoms.

How is testicular cancer diagnosed?

To help find the cause of symptoms, the doctor evaluates a man's general health. The doctor also performs a physical exam and may order laboratory and diagnostic tests. These tests include:

  • Blood tests that measure the levels of tumor markers. Tumor markers are substances often found in higher-than-normal amounts when cancer is present. Tumor markers such as alpha-fetoprotein (AFP), Beta-human chorionic gonadotropin (ßHCG), and lactate dehydrogenase (LDH) may suggest the presence of a testicular tumor, even if it is too small to be detected by physical exams or imaging tests.


  • Ultrasound, a test in which high-frequency sound waves are bounced off internal organs and tissues. Their echoes produce a picture called a sonogram. Ultrasound of the scrotum can show the presence and size of a mass in the testicle. It is also helpful in ruling out other conditions, such as swelling due to infection or a collection of fluid unrelated to cancer.


  • Biopsy (microscopic examination of testicular tissue by a pathologist) to determine whether cancer is present. In nearly all cases of suspected cancer, the entire affected testicle is removed through an incision in the groin. This procedure is called radical inguinal orchiectomy. In rare cases (for example, when a man has only one testicle), the surgeon performs an inguinal biopsy, removing a sample of tissue from the testicle through an incision in the groin and proceeding with orchiectomy only if the pathologist finds cancer cells. (The surgeon does not cut through the scrotum to remove tissue. If the problem is cancer, this procedure could cause the disease to spread.)

If testicular cancer is found, more tests are needed to find out if the cancer has spread from the testicle to other parts of the body. Determining the stage (extent) of the disease helps the doctor to plan appropriate treatment.
