Everything You Need to Know About Peritoneal Mesothelioma


Welcome, readers. In this article, we will discuss a rare yet serious form of mesothelioma, known as peritoneal mesothelioma. This type of cancer affects the lining of the abdomen and is caused by exposure to asbestos. At present, there is no cure for peritoneal mesothelioma, but early detection and treatment can help manage symptoms and improve the quality of life for patients.

This article will provide in-depth information about the causes, symptoms, diagnosis, and treatment of peritoneal mesothelioma. We will also answer some commonly asked questions about this condition to help you understand it better.

What is Peritoneal Mesothelioma?

Peritoneal mesothelioma is a type of cancer that affects the mesothelial cells lining the abdominal cavity. This cancer is caused by exposure to asbestos fibers, which can be inhaled or ingested and become lodged in the lining of the lungs, abdomen, or other organs.

The mesothelial cells in the lining of the abdomen are responsible for producing a lubricating fluid that allows the organs to move smoothly against each other. When these cells become cancerous, they produce excess fluid, causing swelling and inflammation in the abdomen.

What Causes Peritoneal Mesothelioma?

The primary cause of peritoneal mesothelioma is exposure to asbestos. Asbestos is a fibrous mineral that was commonly used in construction, shipbuilding, and other industries until the 1970s. When asbestos fibers are inhaled or ingested, they become lodged in the body’s tissues and can cause cancerous changes over time.

People who have worked in industries like construction, shipbuilding, automotive, and mining, or who have been exposed to asbestos in their homes or environments, are at the highest risk of developing peritoneal mesothelioma.

What are the Symptoms of Peritoneal Mesothelioma?

Peritoneal mesothelioma symptoms can take years or even decades to develop after exposure to asbestos. The symptoms of peritoneal mesothelioma may include:

Symptom Description
Abdominal Pain and Swelling Excess fluid buildup in the abdomen can cause pain and swelling
Nausea and Vomiting The presence of cancer cells and fluid buildup can cause gastrointestinal issues.
Bowel Obstruction As the tumor grows, it can obstruct the bowels and cause difficulty in passing stool.
Unexplained Weight Loss Cancer-related weight loss can affect the appetite and overall health of the patient.
Fever A fever can develop due to the body’s immune response to cancer cells.
Fatigue and Weakness The cancer cells and the body’s immune response can both cause fatigue and weakness.

How is Peritoneal Mesothelioma Diagnosed?

Diagnosing peritoneal mesothelioma is challenging, as the symptoms are similar to those of other abdominal diseases. To diagnose peritoneal mesothelioma, a doctor may perform a physical exam, medical history, imaging tests (X-ray, CT scan, or MRI), and biopsy of the affected tissues.

The diagnosis of peritoneal mesothelioma usually requires obtaining a biopsy of the affected area. A biopsy involves taking a small tissue sample and examining it under a microscope to look for cancer cells.

What are the Treatment Options for Peritoneal Mesothelioma?

Treatment options for peritoneal mesothelioma depend on the stage and location of the cancer, as well as the overall health of the patient. Common treatment options for peritoneal mesothelioma include:

  • Surgery: Removal of the affected tissues or organs that have cancerous cells to prevent further growth
  • Chemotherapy: Use of medicines that kill or slow the growth of cancer cells
  • Radiation Therapy: Use of high-energy rays to kill cancer cells and prevent their growth
  • Immunotherapy: Use of drugs that help the body’s immune system fight against cancer cells


1. Can peritoneal mesothelioma be cured?

Currently, there is no cure for peritoneal mesothelioma, but effective treatments can help manage symptoms and improve the quality of life for patients.

2. Is peritoneal mesothelioma hereditary?

No, peritoneal mesothelioma is not hereditary; it is caused by exposure to asbestos fibers.

3. How long does it take for symptoms of peritoneal mesothelioma to manifest?

Symptoms of peritoneal mesothelioma can take years or even decades to manifest after exposure to asbestos.

4. Can peritoneal mesothelioma spread to other parts of the body?

Yes, peritoneal mesothelioma can spread to other parts of the body, including the lungs and other organs.

5. What is the prognosis for peritoneal mesothelioma?

The prognosis for peritoneal mesothelioma depends on the stage and location of the cancer. Early detection and treatment can improve the outcome of the disease.

6. How is peritoneal mesothelioma different from other types of mesothelioma?

Peritoneal mesothelioma affects the lining of the abdomen, while other types of mesothelioma affect the lining of the lungs or other organs.

7. Is asbestos exposure the only cause of peritoneal mesothelioma?

Yes, exposure to asbestos is the primary cause of peritoneal mesothelioma.

8. Can peritoneal mesothelioma be detected through blood tests?

No, blood tests cannot confirm the presence of peritoneal mesothelioma. A biopsy of the affected tissues is required for a definitive diagnosis.

9. Does peritoneal mesothelioma have any non-cancerous treatment options?

Currently, there are no non-cancerous treatment options available for peritoneal mesothelioma.

10. Can diet and exercise help manage peritoneal mesothelioma?

Diet and exercise can help manage the symptoms of peritoneal mesothelioma and improve the overall health of the patient. However, they cannot cure the disease.

11. Is peritoneal mesothelioma fatal?

Peritoneal mesothelioma can be fatal if it is not detected and treated in the early stages.

12. Can peritoneal mesothelioma recur after treatment?

Yes, peritoneal mesothelioma can recur after treatment. Regular follow-ups with the doctor are necessary to monitor the patient’s condition.

13. Can peritoneal mesothelioma affect children?

No, peritoneal mesothelioma is extremely rare in children and is typically only seen in adults with asbestos exposure.


In conclusion, peritoneal mesothelioma is a rare and serious type of cancer caused by exposure to asbestos fibers. Early detection and treatment can help manage symptoms and improve the quality of life for patients. If you suspect that you or someone you know may have been exposed to asbestos or are experiencing symptoms of peritoneal mesothelioma, consult a healthcare professional immediately.

It is also important to become aware of the dangers of asbestos exposure and take steps to minimize exposure to this harmful substance, including the use of protective clothing and masks in industries where asbestos exposure is common. Together, we can work towards preventing the spread of peritoneal mesothelioma and other asbestos-related illnesses.
