Testicular Cancer and Fertility Preservation Options

Testicular cancer is one of the most common cancers among young men aged 15 to 35 years. To raise awareness, April is recognized as Testicular Cancer Awareness Month by the Testicular Cancer Society. However, awareness should continue year-round to support patients, survivors, and their loved ones.

What is Testicular Cancer?

Testicular cancer occurs in the testes, which are located inside the scrotum—a loose bag of skin beneath the penis. The testes are crucial for producing male hormones and sperm. Though rare, testicular cancer is the most common cancer in young males. Fortunately, it is highly treatable, even if it has spread beyond the testicles. Treatment varies depending on the cancer's nature and stage.

Testicular Cancer Symptoms

Testicular cancer symptoms typically affect only one testicle and may include:

A lump in the testicle
A dull ache in the abdomen or groin
A feeling of heaviness in the scrotum
Sudden fluid collection in the scrotum
Pain or discomfort in the testicle or scrotum
Breast enlargement or tenderness
Back pain

If you notice any of these symptoms lasting more than two weeks, consult a doctor.

Testicular Cancer Causes

The exact cause of testicular cancer is often unknown. It is believed that DNA changes in testicular cells can lead to cancer. Normally, cells grow and divide in an orderly manner.

However, abnormalities can cause uncontrolled growth, forming a mass in the testicle.

Most testicular cancers start in germ cells, which produce immature sperm. The reasons why germ cells become abnormal are still unclear.

Testicular Cancer Risk Factors

Testicular cancer risk factors include:

Age: Most commonly affects men aged 15-35, but can occur at any age.
Ethnicity: More common in white men than black men.
Family History: Increased risk if a family member had testicular cancer.
Cryptorchidism: Undescended testicle increases risk.
Abnormal Testicle Development: Conditions like Klinefelter syndrome can raise risk.

Testicular Cancer Diagnosis

Men often discover testicular cancer themselves during self-examinations or routine check-ups. To diagnose testicular cancer, doctors may use:

Ultrasound: To determine if lumps are solid or fluid-filled.
Blood Tests: To check for elevated tumor markers, indicating potential cancer.
Surgery: To remove a testicle for analysis if cancer is suspected.

Types of Testicular Cancer

There are two main types of testicular cancer:

Seminoma: Can occur at any age, less aggressive, treated with radiation therapy.
Non-seminoma: Typically occurs earlier in life and spreads rapidly. Types include choriocarcinoma, embryonal carcinoma, teratoma, and yolk sac tumor. Chemotherapy is often used as these cancers are less responsive to radiation.

Testicular Cancer Treatment

Testicular cancer treatment depends on the cancer stage and its spread. Treatment options include:

Surgery: Radical inguinal orchiectomy to remove the affected testicle.
Radiation: Effective for seminoma type but may affect sperm count. Discuss fertility preservation with your doctor.
Chemotherapy: Uses drugs to kill cancer cells. Side effects can include fatigue, nausea, and potential infertility. Discuss fertility preservation before starting treatment.

Fertility Preservation Options

Fertility preservation is crucial for men undergoing cancer treatments that may impact sperm production. Options include:

Sperm Freezing: Freeze sperm before treatment for future use in IVF.
Testicular Tissue Cryopreservation (TESE): Extract and freeze testicular tissue for potential future use.
Radiation Shielding: Special shields during radiation to protect testicular cells.

Conclusion

While testicular cancer is treatable with high survival rates, discussing fertility preservation options before starting treatment is vital for future planning. Awareness and timely intervention can make a significant difference in managing testicular cancer effectively.
