Malignant mesothelioma is a form of cancer caused by asbestos exposure that most commonly develops in the lining of the lungs, known as the pleura. Mesothelioma cancer can also affect the lining of the abdomen. In rare instances, tumors may develop in the lining of the heart or testes. It’s an aggressive disease, but treatments like surgery, chemotherapy, and immunotherapy have helped patients live longer, fuller lives after a diagnosis.
Manufacturers of asbestos-containing products hid the link between asbestos and mesothelioma for decades to keep making profits. As a result, millions of civilian workers, military personnel, and their families were exposed to asbestos without knowing the risks.
It takes 10 to 50 years after asbestos exposure for mesothelioma to develop.
The process includes four key stages:
Anyone exposed to asbestos — directly or secondhand — is at risk of developing mesothelioma and other diseases like lung cancer or asbestosis later in life.

The symptoms of mesothelioma can vary based on where the cancer forms in the body. However, there are some general mesothelioma symptoms that are common among patients.
These include:
If the cancer is caught in the early stages, most patients experience mild and vague symptoms. Once the cancer starts to spread, more severe systemic symptoms (symptoms affecting the entire body) may appear.

Illustration of peritoneal mesothelioma
Peritoneal mesothelioma is the second most common type of this cancer, making up 10% to 15% of all cases, according to MD Anderson Cancer Center. This type of mesothelioma develops in the abdominal lining, also known as the peritoneum.
Because peritoneal mesothelioma doesn’t directly affect the heart or lungs unless it spreads, patients diagnosed with this type often have higher survival rates than those with pleural mesothelioma.
More than half of patients live at least 5 years after diagnosis if they undergo cytoreductive surgery with HIPEC (hyperthermic intraperitoneal chemotherapy), according to a 2022 article in the Journal of Clinical Haematology.
Pericardial mesothelioma forms in the pericardium, which is the tissue surrounding the heart. This type of cancer makes up less than 1% of all mesothelioma cases and has a poor prognosis.
A 2021 study found that pericardial mesothelioma patients have an average life expectancy of 2 months.
Testicular mesothelioma develops in the lining of the testes, also called the tunica vaginalis. Only 151 cases of testicular mesothelioma have been reported over the past 11 years. Despite it being a rare diagnosis, it is highly treatable.
According to a report published in the journal Environmental Health, the average life expectancy with testicular mesothelioma is 46.7 months.
Illustration of pleural mesothelioma
Malignant pleural mesothelioma forms in the lining of the lungs and chest wall. This type makes up over 75% of reported mesothelioma cases, according to the American Cancer Society (ACS).
Pleural mesothelioma is characterized by four stages. Early stages of mesothelioma typically mean the cancer is limited to the chest area and hasn’t spread to nearby lymph nodes. Later stages of pleural mesothelioma can spread to distant organs.
The staging of pleural mesothelioma helps doctors determine the type of treatment a patient will receive. Early stages are easier to treat with pleural mesothelioma surgery.

All patients can benefit from mesothelioma treatment in some way, whether to potentially increase their life expectancy or reduce symptoms. Which treatments will work best depends on many patient health factors, such as the type and stage of their cancer.

Got a question? We’re here to help.
Yes, mesothelioma is a type of cancer caused by breathing in or swallowing asbestos fibers. Over decades, asbestos can cause healthy cells in the body to mutate and become cancerous.
Roughly 3,000 people are diagnosed with mesothelioma in the U.S. each year, according to the American Cancer Society.
Mesothelioma is a type of cancer that affects different parts of the mesothelium, which is the thin layer of tissue that lines most of the body’s internal organs.
It can occur in various parts of the body, but the most common form is pleural mesothelioma, which affects the lining of the lungs (pleura).
Other less common types include peritoneal mesothelioma (affects the abdominal lining), pericardial mesothelioma (affects the heart lining), and testicular mesothelioma (affects the lining of the testicles).
Mesothelioma is primarily triggered by exposure to asbestos, a naturally occurring mineral that was widely used in various industries for its heat resistance and insulating properties.
When asbestos fibers are released into the air and breathed in or swallowed, they can become trapped in the lining of the lungs, abdomen, or other organs, leading to inflammation, scarring, and eventually the development of mesothelioma cancer.
If you or a loved one has mesothelioma, our team can help determine when, where, and how your asbestos exposure happened and see if you qualify for compensation. Call (855) 299-2694 to get started.
Mesothelioma can cause painful symptoms, but the level of discomfort is unique to each patient and can fluctuate based on the stage of the disease.
In advanced stages, patients can have more severe chest pain from tumors pressing against nearby tissues or organs.
