Peritoneal Mesothelioma


Peritoneal Mesothelioma is much more rare than Pleural Mesothelioma, but is the second most common type of mesothelioma. Tumors form in the abdominal lining. The peritoneum is a protective membrane that surrounds the abdomen. Peritoneal mesothelioma can develop on both layers, the parietal layer and the visceral layer.

Peritoneal mesothelioma is caused from asbestos exposure, when asbestos dust in ingested, rather than inhaled. Swallowed fibres travel through the digestive system to the peritoneum.

The survival rate depends on the stage of cancer and types of cancer treatment available. Surgery normally plays a major role in survival. Patients that qualify for surgery can live five years or more.

Misdiagnosis is common, because this type of cancer is so rare. Some of our clients have had to fight for their life and healthcare when it came to properly diagnosing this disease.

Stages of Peritoneal Mesothelioma

Stage 1: Cancerous tissue is minimal and tumors are contained within the abdominal lining, and lymph nodes are free of cancer.

Stage 2: Cancerous tissue is moderate and tumors have not spread outside the lining or to lymph nodes

Stage 3: Cancerous tissue is more extensive and tumors may have spread outside the peritoneal lining, to lymph nodes or both.


Treatment includes surgery, chemotherapy and immunotherapy. Doctors often believe that combining treatment often works best, rather than one treatment. Surgery is the most promising treatment option, but only effective for early-stage cancer. Chemotherapy can shrink the tumors and slow the growth of the spread of cancer.
