Introduction
Greetings, readers! In this article, we will delve into the topic of pleural and peritoneal mesothelioma. As you may know, mesothelioma is a rare and aggressive type of cancer that affects the lining of the lungs, heart, and abdomen. This disease is primarily caused by exposure to asbestos, a fibrous mineral that was commonly used in construction, shipbuilding, and other industries until the 1970s.
Despite the declining use of asbestos in recent decades, mesothelioma remains a significant public health concern, with thousands of new cases diagnosed each year. If you or someone you know has been exposed to asbestos or has been diagnosed with mesothelioma, it’s crucial to understand the disease’s nature, symptoms, treatment options, and prognosis.
Let’s get started by examining the difference between pleural and peritoneal mesothelioma.
Pleural Mesothelioma
What is Pleural Mesothelioma?
Pleural mesothelioma is the most common form of mesothelioma, accounting for 75% of all cases. It affects the membrane (pleura) that lines the lungs’ outer surface and the chest wall’s inner surface. The disease typically develops years or even decades after exposure to asbestos fibers, which can become lodged in the lung tissue and cause inflammation, scarring, and tumor growth.
Symptoms and Diagnosis of Pleural Mesothelioma
The symptoms of pleural mesothelioma can vary widely, with some patients experiencing no symptoms initially. However, as the disease progresses, common symptoms may include:
– Chest pain or discomfort- Persistent coughing- Shortness of breath- Fatigue or weakness- Unintentional weight loss- Difficulty swallowing
If you are experiencing any of these symptoms and have a history of asbestos exposure, you should see a doctor right away. To diagnose pleural mesothelioma, your doctor may perform a physical exam, imaging tests, such as X-rays, CT scans, and MRIs, and biopsy tests, in which a small sample of tissue is taken from the pleural lining for examination under a microscope.
Treatment Options for Pleural Mesothelioma
Treatment options for pleural mesothelioma depend on several factors, including the tumor size and location, the disease stage, and the patient’s overall health. Treatment may include:
– Surgery: In some cases, surgeons may remove the affected lung or part of it to remove as much of the tumor as possible. Other surgical procedures may aim to relieve symptoms, such as draining fluid from the chest cavity or removing part of the pleura lining.- Radiation therapy: High-energy radiation beams may be used to shrink the tumor or reduce pain and discomfort in the chest area.- Chemotherapy: Powerful drugs may be used either before or after surgery to kill cancer cells or slow their growth.- Immunotherapy: This emerging form of treatment uses drugs that help the immune system recognize and attack cancer cells.
Prognosis for Pleural Mesothelioma
The prognosis for pleural mesothelioma is generally poor, with an average life expectancy of 12-21 months after diagnosis. However, early detection, a favorable disease stage, and aggressive treatment may improve survival rates. Clinical trials of new treatments and therapies also provide hope for future mesothelioma patients.
Peritoneal Mesothelioma
What is Peritoneal Mesothelioma?
Peritoneal mesothelioma is a rare type of mesothelioma that affects the lining (peritoneum) of the abdomen. It accounts for about 20% of all mesothelioma cases and is also caused by exposure to asbestos fibers, which can migrate to the peritoneum and cause inflammation and tumor growth.
Symptoms and Diagnosis of Peritoneal Mesothelioma
The symptoms of peritoneal mesothelioma include:
– Abdominal pain or swelling- Nausea or vomiting- Loss of appetite- Unintentional weight loss- Bowel or urinary problems- Fatigue or weakness
Diagnosis of peritoneal mesothelioma may involve imaging tests, such as CT scans or MRIs, and biopsy tests, in which a small sample of tissue is taken from the peritoneum for examination under a microscope.
Treatment Options for Peritoneal Mesothelioma
Treatment options for peritoneal mesothelioma may include:
– Surgery: Surgeons may remove parts of the affected organs or the entire peritoneum lining to remove as much of the tumor as possible. They may also perform heated intraperitoneal chemotherapy (HIPEC), a procedure in which heated chemotherapy drugs are circulated in the abdomen to kill cancer cells.- Radiation therapy: Radiation beams may be used to target the tumor or relieve abdominal pain and discomfort.- Chemotherapy: Chemotherapy drugs may be used to kill cancer cells or slow their growth.
Prognosis for Peritoneal Mesothelioma
The prognosis for peritoneal mesothelioma is generally better than for pleural mesothelioma, with a median survival rate of 53 months after diagnosis. However, the disease is still considered incurable, and treatment may focus on relieving symptoms and improving quality of life.

FAQs
What Causes Mesothelioma?
Mesothelioma is primarily caused by exposure to asbestos, a mineral that was widely used in construction and other industries until the 1970s. When asbestos fibers are inhaled or ingested, they can become lodged in the lining of the lungs, heart, or abdomen and cause inflammation, scarring, and tumor growth over time.
Can You Get Mesothelioma Without Asbestos Exposure?
Although asbestos exposure is the leading cause of mesothelioma, there have been rare cases of the disease occurring in people with no known exposure to asbestos. Other possible risk factors for mesothelioma include exposure to radiation, zeolite fibers, and certain viruses or genetic mutations.
What are the Stages of Mesothelioma?
Mesothelioma is typically staged from 1 to 4, with higher stages indicating more advanced disease. Staging is based on several factors, including tumor size and location, lymph node involvement, and the extent of metastasis (spread) to other parts of the body.
How is Mesothelioma Treated?
Treatment for mesothelioma may include surgery, radiation therapy, chemotherapy, immunotherapy, or a combination of these approaches. Treatment options depend on several factors, including the type and stage of the disease, the patient’s overall health, and the potential risks and benefits of each option.
What is the Prognosis for Mesothelioma?
The prognosis for mesothelioma varies depending on several factors, including the disease stage, location, and type, as well as the patient’s age, sex, and overall health. Generally, mesothelioma has a poor prognosis, with a median survival time of 12-21 months for pleural mesothelioma and 53 months for peritoneal mesothelioma.
