Mesothelioma is a rare and aggressive form of cancer that develops in the protective lining, known as the mesothelium, that covers various organs in the body. This article aims to provide a comprehensive guide to understanding mesothelioma, including its causes, symptoms, types, stages, diagnosis, prognosis, treatment options, and financial support available for patients.
Understanding Mesothelioma
What is Mesothelioma?
Mesothelioma is a malignant cancer that primarily affects the mesothelium, a thin layer of tissue that lines the lungs, abdomen, heart, and testicles. It is mainly caused by exposure to asbestos, a naturally occurring mineral widely used in various industries for its heat resistance and insulation properties.
Quick Facts About Mesothelioma
-
Approximately 3,000 Americans are diagnosed with mesothelioma each year.
-
Symptoms of mesothelioma include cough, shortness of breath, fluid buildup, abdominal or chest pain, weight loss, and loss of appetite.
-
Veterans make up around 30% of all mesothelioma cases.
-
Patients diagnosed with mesothelioma may qualify for financial compensation, with average settlements ranging from $1 million to $1.4 million.
How Does Asbestos Exposure Cause Mesothelioma?
The Link Between Asbestos and Mesothelioma
Asbestos is the primary cause of mesothelioma, and exposure to asbestos fibers is the only known cause of this aggressive cancer. When asbestos-containing materials are disturbed, such as during construction or demolition work, microscopic asbestos fibers can be released into the air. These fibers can then be inhaled or ingested, leading to their accumulation in the protective linings of organs.
The Mechanism of Asbestos-Induced Mesothelioma
Once asbestos fibers are lodged in the mesothelium, they can cause inflammation and irritation over time. This chronic irritation can eventually lead to the development of cancerous tumors. Unfortunately, the link between asbestos and mesothelioma was hidden by companies manufacturing asbestos-containing products for many years, resulting in countless individuals being exposed to asbestos without knowledge of the associated risks.
“I was exposed to asbestos through Sheetrock® products, the mud, through gaskets in piping, through respirators. The cartridges and the filters had asbestos in them. All through my career.” – John Stahl, stage 4 mesothelioma survivor
Anyone who has been directly or indirectly exposed to asbestos is at risk of developing mesothelioma or other asbestos-related diseases, such as lung cancer or asbestosis, later in life.
Malignant Mesothelioma Symptoms
Symptoms of mesothelioma can vary depending on the location of the cancer within the body. However, some general symptoms are common among many patients. These symptoms may include:
-
Abdominal or chest pain
-
Persistent cough
-
Shortness of breath
-
Fluid buildup in the chest or abdomen
-
Loss of appetite
-
Nausea and vomiting
-
Night sweats
-
Weight loss
It is important to note that early-stage mesothelioma often presents with mild and vague symptoms. As the disease progresses, more severe systemic symptoms may arise. If individuals experience persistent symptoms that do not improve, it is essential to seek medical attention and encourage further testing.
“If you feel like you’re not getting better and that this is something new for you, it’s best to encourage your doctor to proceed with more testing.” – Amy Fair, RN, Mesothelioma Hope Patient Advocate
Mesothelioma Types
Mesothelioma can occur in different locations within the body, resulting in distinct types of the disease. The four primary types of mesothelioma are pleural mesothelioma, peritoneal mesothelioma, pericardial mesothelioma, and testicular mesothelioma. Understanding these types can help with accurate diagnosis and appropriate treatment planning.
Pleural Mesothelioma
Pleural mesothelioma is the most common type of mesothelioma, accounting for over 75% of reported cases. It develops in the pleura, the lining of the lungs and chest wall. The American Cancer Society (ACS) categorizes pleural mesothelioma into four stages, ranging from limited chest area involvement in early stages to spread to distant organs in later stages. Treatment options for pleural mesothelioma include surgery, chemotherapy, radiation therapy, and immunotherapy.
Peritoneal Mesothelioma
Peritoneal mesothelioma is the second most common type, comprising 10% to 16% of mesothelioma cases. It develops in the peritoneum, the lining of the abdominal cavity. Innovative treatments, such as cytoreductive surgery with HIPEC (hyperthermic intraperitoneal chemotherapy), have significantly improved survival rates for patients with peritoneal mesothelioma.
Pericardial Mesothelioma
Pericardial mesothelioma is a rare form of mesothelioma that affects the tissue surrounding the heart, known as the pericardium. It accounts for less than 1% of all mesothelioma cases and has a poor prognosis. Research and treatment options for pericardial mesothelioma are limited due to its rarity.
Testicular Mesothelioma
Testicular mesothelioma is an extremely rare form of the disease, with only 151 cases reported over the past 11 years. It develops in the lining of the testes, called the tunica vaginalis. Despite its rarity, testicular mesothelioma is highly treatable, with patients often experiencing a relatively long average life expectancy.
“The average life expectancy was 72.5 months, with many patients living past that number.” – A 2022 review of the National Cancer Database
The Four Stages of Mesothelioma Cancer
Staging mesothelioma is crucial for determining the extent of the disease and guiding treatment decisions. The four stages of mesothelioma provide doctors and patients with valuable information about the spread of cancer throughout the body.
Stage 1
Stage 1 mesothelioma indicates that the cancer is localized and has not spread beyond its point of origin. The average life expectancy for patients at this stage is about 21 months. Surgery is often recommended as a treatment option, which may increase survival time by several months or even years.

Stage 2
In stage 2, mesothelioma has spread beyond the lining of the lungs or abdomen into nearby lymph nodes or tissues. The average life expectancy for patients at this stage is around 19 months. Treatment options may include surgery and other multimodal approaches to slow disease progression and extend survival.
“Surgery is often explored as a treatment option to help patients live longer.” – Learn More About Stage 2
Stage 3
Stage 3 mesothelioma indicates that the cancer has further spread into nearby tissues, organs, or lymph nodes. The average life expectancy for patients at this stage is approximately 16 months. Treatment focuses on managing symptoms, slowing disease spread, and providing palliative care to improve quality of life.
“Treatments focus on slowing disease spread and managing pain.” – Learn More About Stage 3
Stage 4
Stage 4 mesothelioma represents the most advanced stage of the disease, with cancer cells having invaded distant parts of the body. The average life expectancy for patients at this stage is about 12 months. Treatment options primarily focus on palliative care to relieve pain and improve quality of life.

Diagnosing Mesothelioma
Accurate and timely diagnosis is critical for mesothelioma patients to receive appropriate treatment. The diagnostic process typically involves a series of steps, including a physical examination, imaging tests, and a biopsy.
Physical Examination
When individuals present with symptoms suggestive of mesothelioma, doctors will conduct a thorough physical examination. Patients are encouraged to inform their doctors about any prior exposure to asbestos.
Imaging Tests
Imaging tests, such as chest X-rays, CT scans, and MRIs, are commonly used to visualize the affected areas of the body. These scans help doctors identify possible signs of mesothelioma, such as pleural thickening and fluid buildup.
Biopsy
A biopsy is the only definitive way to confirm a diagnosis of mesothelioma. During a biopsy, doctors collect a sample of fluid or tissue from the affected area and examine it under a microscope for the presence of malignant mesothelial cells. There are three main cell types associated with mesothelioma: epithelioid, sarcomatoid, and biphasic.
Second Opinion
It is always recommended to seek a second opinion, regardless of the initial diagnosis. Obtaining another expert’s perspective can help ensure an accurate diagnosis and appropriate treatment plan. A mesothelioma specialist can review the original results and provide further guidance if a patient is misdiagnosed.
“Patients should get a second opinion, no matter the diagnosis. With a second opinion, another mesothelioma specialist will review the original results and recommend the following steps if a patient is misdiagnosed.”
