Testicular Mesothelioma

Mesothelioma occurs when cancer attacks the mesothelium, which consists of mesothelial cells forming a protective layer over the body's cavities and organs. The mesothelium produces fluids which protect the organs and allow for their movement. The lining located in the chest is called the pleura and the lining of the abdomen is referred to as the peritoneum.
Types of Mesothelioma

Of malignant mesotheliomas, the most common is pleural mesothelioma, which occurs in the chest and is responsible for approximately 90% of mesothelioma cancers in men. One of the rarest forms of mesothelioma is testicular, accounting for only 0.7% of all cases between 1973 and 1999. Testicular mesothelioma has been known to occur over a wide age range although most patients are adults over the age of 50. Caucasians are the most subject to the cancer, particularly those who work industrial or construction labor.
Causes of Mesothelioma

The primary factor known to cause malignant mesothelioma is previous asbestos exposure. Asbestos is a type of mineral composed of magnesium-silicate fibers. A popular form of insulation, asbestos was preferred due to its fire resistance and strength. When research showed that asbestos posed health concerns, the popularity of the mineral began to decrease. However, although it is not considered a popular constructive material today, it is still present in many buildings and homes that were constructed during the 20th century.

Asbestos occurs naturally and is present not only in old buildings but also in mines, shipyards, brake pads, insulation in ducts, as well as in various manufacturing facilities. The most common victims of asbestos exposure are veterans of the U.S. Navy and blue-collar workers. Secondhand exposure is also common among family members who come into contact with the employees and their clothing.
Symptoms of Testicular Mesothelioma

The primary symptom of testicular mesothelioma is often a simple lump leading to delayed diagnosis. Therefore, the disease is often advanced before a successful diagnosis is made. Because the cancer is very aggressive, patients typically do not survive more than one year following diagnosis.

Fortunately, testicular mesothelioma is extremely uncommon. However, due to its aggressive nature and the fact that the cancer often reoccurs, metastasis or spreading to areas such as the lungs, chest, brain, and lymph nodes is likely. Because of this, the life expectancy of a patient with testicular mesothelioma is typically less than 2 years.
Treating the Disease

Early cases of the cancer can occasionally be treated with surgical removal with chemotherapy and radiation treatment being used as well. Unfortunately, in later stages, the cancer is completely incurable and the most that can be done is to relieve the discomfort of the patient.
