Peritoneal mesothelioma is a rare and aggressive cancer that forms in the lining of the abdomen, called the peritoneum.

It is caused by exposure to asbestos, a harmful mineral once widely used in construction and manufacturing..

Peritoneal mesothelioma often develops decades after asbestos exposure, and while it can feel overwhelming, advancements in treatment offer hope for many patients and their families.

Mesothelioma is categorized as different types based on where it develops in the body.

The other types of mesothelioma are:

• Pleural mesothelioma (lungs): The most common type of mesothelioma affecting the chest and lungs

• Pericardial mesothelioma (heart): A very rare type which develops around the heart

• Testicular mesothelioma (testes): The rarest type, affecting the lining of the testes.

Knowing the type of mesothelioma is important as it can help you determine the best treatment options available and which specialists to see.

To confirm peritoneal mesothelioma, a biopsy is most often performed, where a tissue sample from the affected area is examined under a microscope for cancer cells.

Before a biopsy, doctors often use imaging tests like X-rays, CT scans, or MRIs to detect abnormalities and determine the best area for tissue sampling.

The most common biopsy method for peritoneal mesothelioma is a laparoscopy, where a thin flexible instrument with a light and camera (a laparoscope) is inserted into the abdomen to collect tissue samples for an accurate diagnosis.

If you or a loved one has been diagnosed with mesothelioma, it’s important to seek expert guidance as soon as possible. Early diagnosis offers a wider range of treatment options and can improve outcomes.

Many veterans were exposed to asbestos during their military service, particularly between the 1930s and 1970s, when asbestos was heavily used in Navy ships, military buildings, aircrafts, and vehicles.

This exposure puts veterans at a higher risk of developing mesothelioma, a disease that can take decades to appear after initial exposure.

Veterans account for about 30% of all mesothelioma patients. Fortunately, there are additional veterans benefits and specialized care programs designed to support veterans and their families through this difficult journey.
