Testicular mesothelioma is the rarest form of mesothelioma. It occurs in less than one percent of all mesothelioma diagnoses.

The Rarest Form of Mesothelioma

Mesothelioma typically presents itself in the chest or abdomen, but in rare circumstances, it can develop in the testicles. Testicular mesothelioma occurs when mutated cells in the lining surrounding the testicle begin replicating uncontrollably.

Understanding Testicular Mesothelioma

  • Development

    Little is known about how this cancer develops. Unlike other forms of mesothelioma, there isn’t any conclusive evidence linking asbestos exposure to testicular mesothelioma.

  • Symptoms

    Common symptoms, such as pain and swelling, are similar to several other illnesses. This is why a tissue biopsy is recommended to get an accurate diagnosis.

  • Treatment

    Surgery is the foundation for treating testicular mesothelioma. Chemotherapy and radiation are also used.

  • Prognosis

    Patients with testicular mesothelioma generally live 20 months or longer after their diagnosis. Testicular mesothelioma has a slightly better prognosis than mesothelioma in the chest or abdomen.

How Does Mesothelioma Develop in the Testicles?

Mesothelioma is caused by a mutation of mesothelial cells that make up the lining of certain organs, most commonly the lungs. Mesothelial linings help provide movement for organs like the lungs to expand and contract. These linings are also integral in allowing free movement for the testicles.

The lining of the testicles is known as the tunica vaginalis. When mesothelioma develops in the tunica vaginalis, the lining starts to thicken and produce fluid buildup.

There is a significant lack of research on testicular mesothelioma at this time. Although, asbestos exposure has been associated with some cases of testicular mesothelioma, there isn’t any concrete evidence to support asbestos exposure as a definitive cause of this disease.

Approximately 35 percent of all testicular mesothelioma patients have had a history of asbestos exposure.

Although asbestos hasn’t been definitively linked to testicular mesothelioma, asbestos is known to lodge into the lining of organs. It is also capable of traveling through the body. Several workers with histories of occupational asbestos exposure diagnosed with testicular mesothelioma have even won legal claims because of the known dangers of asbestos.
